sostengono che questo nuovo ritrovamento costituirà una notevole banca dati

è stata scoperta casualmente il 24 febbraio 1939. Sepolta da un crollo avvenuto
circa 60 anni fa, è stata poi studiata dal paleontologo francese <span style="mso-bidi-font-weight: bold;">Alberto Carlo Blanc.</span> Oggi gli
archeologi, richiamati allo studio di questo sito, preziosamente conservato nel
tempo, sono intervenuti con </span><span style="font-family: arial; font-size: large;">l’aiuto delle nuove tecnologie e la scorta delle
conoscenze derivate da 80 anni di lavori di scavo, allargando una zona inedita
della grotta, fino ad ora mai esplorata. Come ha raccontato </span><span style="font-family: arial; font-size: large;">Francesco Di Mario</span><span style="font-family: arial; font-size: large;">, il funzionario che
ha condotto la campagna, tra i 9 scheletri rinvenuti ci sono un giovane e
una femmina, appartenenti tuttavia a diverse epoche. “</span><i style="font-family: arial; font-size: large;">È una rappresentazione
soddisfacente di una popolazione che doveva essere abbastanza numerosa in zona.
Stiamo portando avanti gli studi e le analisi, non solo genetiche, con tecniche
molto più avanzate rispetto ai tempi di Blanc, capaci di rivelare molte
informazioni”. </i><span style="font-family: arial; font-size: large;">Ed è subito mistero.</span></span></p><p class="MsoNormal" style="background: white; line-height: 19.5pt; margin-bottom: 19.5pt; text-align: justify;"><a href="https://1.bp.blogspot.com/-qRwRDobFrmk/YJlSwNRwaBI/AAAAAAAAQg4/DnHrIQsl3gEDoQ0WT7FvjVaBqwlVvClGACLcBGAsYHQ/s630/13_Immagini_HD_Neanderthal_crediti_%25C2%25A9%25EF%25B8%258F_UfficioStampaEComunicazione_MiC_Foto_di_Emanuele_Antonio_Minerva-630x420.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img border="0" data-original-height="420" data-original-width="630" src="https://1.bp.blogspot.com/-qRwRDobFrmk/YJlSwNRwaBI/AAAAAAAAQg4/DnHrIQsl3gEDoQ0WT7FvjVaBqwlVvClGACLcBGAsYHQ/s320/13_Immagini_HD_Neanderthal_crediti_%25C2%25A9%25EF%25B8%258F_UfficioStampaEComunicazione_MiC_Foto_di_Emanuele_Antonio_Minerva-630x420.jpg" width="320" /></a></p>

chiarire gli enigmi della Grotta Guattari, ma già ci sono i primi dettagli dati
dall’analisi delle ossa, e che portano alla luce frammenti di vita, a partire
dalla dieta degli ominidi, prettamente vegetariana. Insieme ai corpi sono stati
trovati frammenti di rinoceronti, iene, elefanti, orsi delle caverne e uro, un
grande bovino ormai estinto. Qui il video che racconta la scoperta. “<i>Con
questa campagna di scavo”, </i>ha detto Mario Rubini, direttore del
servizio di antropologia della SABAP per le province di Frosinone e Latina “<i>abbiamo
trovato numerosi individui, una scoperta che permetterà di gettare una luce
importante sulla storia del popolamento dell’Italia. L’uomo di Neanderthal è
una tappa fondamentale dell’evoluzione umana, rappresenta il vertice di una
specie ed è la prima società umana di cui possiamo parlare”. “Una scoperta
straordinaria di cui parlerà tutto il mondo, </i>ha dichiarato il
Ministro della Cultura, Dario
Franceschini, “<i>perché arricchisce le ricerche sull’uomo di
Neanderthal. È il frutto del lavoro della nostra Soprintendenza insieme alle
Università e agli enti di ricerca, davvero una cosa eccezionale”.<o:p></o:p></i></span></p><p></p><p class="MsoNormal" style="background: white; line-height: 31.5pt; margin-bottom: 5.25pt; mso-outline-level: 1; text-align: justify;"><a href="https://1.bp.blogspot.com/-JClqjjNk5Qw/YJlSwziKTmI/AAAAAAAAQg8/o1lA7gUob9oj7PI5Nu7EHtlY4DzLV2JYwCLcBGAsYHQ/s747/19_Immagini_HD_Neanderthal_crediti_%25C2%25A9%25EF%25B8%258F_UfficioStampaEComunicazione_MiC_Foto_di_Emanuele_Antonio_Minerva-747x420.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img border="0" data-original-height="420" data-original-width="747" src="https://1.bp.blogspot.com/-JClqjjNk5Qw/YJlSwziKTmI/AAAAAAAAQg8/o1lA7gUob9oj7PI5Nu7EHtlY4DzLV2JYwCLcBGAsYHQ/s320/19_Immagini_HD_Neanderthal_crediti_%25C2%25A9%25EF%25B8%258F_UfficioStampaEComunicazione_MiC_Foto_di_Emanuele_Antonio_Minerva-747x420.jpg" width="320" /></a></p><p class="MsoNormal" style="background: white; line-height: 31.5pt; margin-bottom: 5.25pt; mso-outline-level: 1; text-align: justify;"><br /></p>CLAUDIO NUCCIhttp://www.blogger.com/profile/10110185451230747837noreply@blogger.com0tag:blogger.com,1999:blog-8925103224850467155.post-79648471591754911082021-03-16T07:28:00.001-07:002021-03-16T07:28:39.929-07:00Homo gautengensis<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-WXLTZSXQPNc/YFC_w4fubnI/AAAAAAAAQd0/pq8uiDdO45MzUaoI4HPiyM7GeOf6XQLewCLcBGAsYHQ/s251/download.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="251" data-original-width="201" src="https://1.bp.blogspot.com/-WXLTZSXQPNc/YFC_w4fubnI/AAAAAAAAQd0/pq8uiDdO45MzUaoI4HPiyM7GeOf6XQLewCLcBGAsYHQ/s0/download.jpg" /></a></div><div class="separator" style="clear: both; text-align: center;"><span style="color: #ff6633; text-align: left;"><span style="font-family: Arial Black, sans-serif;"><span style="font-size: small;"><br /></span></span></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="color: #ff6633; text-align: left;"><span style="font-family: Arial Black, sans-serif;"><span style="font-size: small;">Homo

<span style="color: #ff6633;"><span style="font-family: Arial Black, sans-serif;"><span style="font-size: small;">Curnoe
crede che l'Homo gautengensis fosse alto poco più di un metro, e che

quando si trovava a terra, "ma probabilmente passava molto tempo

Secondo Curnoe l'Australopithecus sediba sembra "molto più
primitivo dell'Homo gautengensis, e visse nello stesso periodo e
nello stesso luogo", per cui "l'Homo gautengensis rende
ancora più improbabile il fatto che l'Australopithecus sediba fosse

esperti internazionali ha suggerito che l'ascesa degli esseri umani
moderni, sia stata una faccenda molto più caotica. Il continente
africano era popolato da tribù separate, sparse attraverso il
continente preistorico e separate da confini naturali, allora
invalicabili come deserti, foreste e fiumi. Con lo scorrere dei

“L’evoluzione delle popolazioni umane in Africa è stata

Il fossile è stato scoperto nella regione di Afar in Etiopia, a 55 chilometri di distanza dal luogo in cui era stata scoperta Lucy. Pubblicato su Nature, il risultato si deve a due studi guidati da Yohannes Haile-Selassie del Cleveland Museum of Natural History.<br />
I lobi mascellare, frontale e parietale, la fossa nasale, le orbite, tutto è incredibilmente ben conservato, nonostante 3,8 milioni di anni trascorsi sottoterra. Questo fossile è quello di un Australopithecus Anamensis, la specie più antica del suo genere. Prima di questa scoperta si era stimato che fossero vissuti tra 4,2 e 3,9 milioni di anni fa. Questa scoperta ringiovanisce questa specie di <a href="tel:100000">100.000</a> anni. È poco su questa scala temporale, ma non è banale. Nel frattempo era stata scoperta un’altra specie di Australopithecus: Afarensis, di cui Lucy è la rappresentante più famosa.<br />
Questo nuovo esemplare implica quindi che entrambe le specie sono state contemporanee per almeno alcune decine di migliaia di anni, mentre gli scienziati hanno pensato fino ad allora che l’una avesse fosse succesiva all’altra.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-q_ESmi2fzQk/X4iB8G8Ze9I/AAAAAAAAQVM/DE6M_F8LJnEdxPt_FoYc9qfOfLtKeFosACLcBGAsYHQ/s1024/Australopithecus-Anamensis-1024x682.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="682" data-original-width="1024" src="https://1.bp.blogspot.com/-q_ESmi2fzQk/X4iB8G8Ze9I/AAAAAAAAQVM/DE6M_F8LJnEdxPt_FoYc9qfOfLtKeFosACLcBGAsYHQ/s320/Australopithecus-Anamensis-1024x682.jpg" width="320" /></a></div><p dir="ltr">
È ancor più interessante che l’ottimo stato di conservazione del cranio abbia permesso di ricostruire il volto di questo individuo nell’immagine sintetica.<br />
Questa datazione di 3,8 milioni di anni è stata resa possibile dall’analisi dei minerali presenti negli strati di roccia vulcanica presenti nell’area di scavo. Combinando le osservazioni fatte sul campo con lo studio di microscopici resti biologici trovati nella regione, i ricercatori sono stati anche in grado di ricostruire il paesaggio e la vegetazione dell’epoca.<br />
Il teschio fossile è stato trovato tra i depositi sabbiosi di una regione in cui un vecchio fiume è entrato in un lago che è scomparso. I movimenti tettonici della Rift Valley etiope hanno poi portato nel corso dei millenni alla nascita delle pianure che caratterizzano la regione di Afar. Gli scienziati hanno anche scoperto chicchi di polline fossili e resti di piante e alghe. Hanno concluso che il lago era circondato da aree boschive, un bacino che era essenzialmente secco e probabilmente salato in determinati periodi.<br />
Tutti questi elementi aiutano a comprendere meglio le evoluzioni delle specie che si sono susseguite nell’Australopithecus e da quando queste specie si sono separate per formare il genere Homo, il nostro.</p>CLAUDIO NUCCIhttp://www.blogger.com/profile/10110185451230747837noreply@blogger.com0tag:blogger.com,1999:blog-8925103224850467155.post-1654693134805435652019-03-19T02:27:00.002-07:002019-03-19T02:27:41.924-07:00ULTIME CREAZIONI<div class="separator" style="clear: both; text-align: center;">

luce gli utensili di pietra più vecchi del mondo: risalgono a 3,3
milioni di anni fa, circa 500.000 anni prima della stima che facciamo
sulla comparsa del genere Homo. Il ritrovamento dimostra che qualche
precedente specie di ominidi aveva sviluppato l'abilità di costruire
rudimentali strumenti litici (armi e arnesi di pietra), rivelando

<b><span style="color: orange;">DAL LEGNO ALLA PIETRA. In natura
diversi primati, come gli scimpanzé o i gorilla, sono in grado di
modellare grossolani arnesi di legno che vengono poi utilizzati per
la caccia e il trattamento del cibo. Finora, però, si riteneva che
l'uomo fosse l'unica specie della famiglia Hominidae capace di
lavorare materiali litici.</span></b></div>
<div style="margin-bottom: 0cm; text-align: justify;">
<b><span style="color: orange;">Secondo le teorie più accreditate, il
primo "uomo" a padroneggiare dei ciottoli scheggiati
(chopper) fu l'Homo abilis, che diede vita alla cosiddetta produzione
"olduvaiana" (dal giacimento di Olduvai Gorge, in
Tanzania), le cui testimonianze più antiche risalgono a 2,6 milioni
di anni fa e segnano l'inizio del Paleolitico Inferiore.</span></b></div>

<b><span style="color: orange;">QUANDO L'UOMO NON C'ERA. Lo studio di
Nature sposta indietro l'origine dei primi utensili di pietra, in un
periodo in cui il genere Homo non era ancora apparso. Al momento non
è possibile stabilire chi sia l'artefice di questi oggetti, tuttavia
i ricercatori hanno già individuato due canditati verosimili.</span></b></div>
<div style="margin-bottom: 0cm; text-align: justify;">
<b><span style="color: orange;">Da un lato abbiamo il Kenyanthropus
platyops, un ominide di classificazione incerta (per alcuni si tratta
di una varietà di Australopithecus afarensis) i cui resti sono stati
rinvenuti nel 1999 a un chilometro di distanza dal sito Lomekwi 3.
Una secondo identikit porta invece direttamente all'Australopithecus
afarensis (quello del fossile Lucy), vissuto in Africa tra 4 e 3
milioni di anni fa. In entrambi i casi si tratta di specie di
proto-uomini ritenute fino a oggi non particolarmente abili,
soprattutto a causa della ridotta capacità cranica.</span></b></div>

<div style="margin-bottom: 0cm; text-align: justify;">
<br /></div>
<div style="margin-bottom: 0cm; text-align: justify;">
<b><span style="color: orange;">EVOLUZIONE UMANA. Gli archeologi
ritengono che gli strumenti non consentissero azioni complesse, ma
servissero per rompere i gusci dei frutti o per scavare nel legno in
cerca di insetti, in modo analogo a ciò che fanno alcune scimmie
antropomorfe. Ma come sottolinea Sonia Harmand, coautrice dello
studio, prima di questa scoperta si pensava che «il salto cognitivo
per ottenere scaglie affilate dalle pietre» riguardasse
esclusivamente il genere Homo, «e fosse la base del nostro successo
evolutivo».</span></b></div>
<div style="margin-bottom: 0cm; text-align: justify;">
<b><span style="color: orange;">Dato che l'abilità di costruire
oggetti richiede un certo livello di destrezza e manualità, i
ritrovamenti di Lomekwi 3 suggeriscono che i necessari cambiamenti
nel sistema nervoso centrale si siano manifestati nei nostri
progenitori prima di 3,3 milioni di anni fa.</span></b></div>
<div style="margin-bottom: 0cm; text-align: justify;">
<b><span style="color: orange;">INDIZI PRECEDENTI. A Dikika, in
Etiopia, nel 2009 un gruppo di ricercatori riportò alla luce i resti
di animali risalenti a 3,4 milioni di anni fa. Le ossa portavano
evidenti segni di tagli, indicando che degli ominidi avevano
padroneggiato delle pietre per tagliare la carne. Sul posto non fu
però trovata alcuna traccia di utensili, quindi fu impossibile
dimostrare se si trattasse di strumenti artigianali o semplici pietre
con spigoli vivi. Lo studio di Nature toglie ora qualunque dubbio.</span></b><br />

<b style="color: orange;">Questo è il procedimento per creare un manufatto preistorico ,dalla scheggiatura all'invecchiamento.</b></div>
<span style="color: orange;"><div style="text-align: justify;">
<b>Prima si scheggia la selce per conferirgli la forma voluta in questo caso un bifacciale musteriano del pontiniano ricavato da un ciottolo siliceo, dopo la scheggiatura viene la fase di levigatura su di una roccia di arenaria , prima dura poi un po piu morbida in maniera da togliere il tagliente e levigare tutte le asperità del manufatto,una volta addolcite le fratture ,viene <span class="text_exposed_hide">...</span><span class="text_exposed_show">passato sulla sabbia per dargli una sorta di semi lucidatura e poi dopo aver lavato il pezzo, lo si passa energicamente su una sabbia compatta di arenaria molto ossidata fino a che il manufatto stesso si impregni delle varie ossidazioni presenti nell'arenaria. A questo punto si prende la selce ancora sporca abbondantemente di arenaria e la si lascia ad asciugare al sole senza pulirla per almeno tre giorni in maniera da fargli assorbire tutte le colorazioni degli ossidi. Una volta asciugata si spazzola energicamente con uno spazzolino a setole dure rendendo il manufatto pulito e lucido come se ci fosse una patina naturale e antica di migliaia di anni fà.</span></b></div>

da quello degli esseri umani moderni per 385 basi (nucleotidi), nel
filamento del DNA mitocondriale è di circa 16.500 basi, mentre la
differenza tra gli esseri umani moderni ed i Neanderthal è di circa
202 basi. Considerando che la differenza tra scimpanzé e gli esseri
umani moderni è di circa 1462 paia di basi del DNA mitocondriale,
ciò suggerisce un tempo di divergenza di circa un milione di anni.
L'mtDNA di un dente portava una somiglianza elevata a quella
dell'osso del dito indicando che entrambi appartenevano alla stessa
popolazione. È stata recuperata una sequenza di mtDNA su un secondo
dente che ha mostrato un numero inaspettatamente elevato di
differenze genetiche rispetto a quella riscontrata nell'altro dente e
nel dito, suggerendo un elevato grado di diversità mtDNA. Questi due
individui rinvenuti nella stessa grotta hanno mostrato una diversità
tra loro maggiore di quella rilevata campionando gli uomini di

essi e le sequenze degli africani moderni è di 804.000 anni fa. Ciò
suggerisce che la divergenza dei risultati mitocondriali del Denisova
derivi o dalla persistenza di un lignaggio epurato dagli altri rami
attraverso deriva genetica oppure da un'introgressione di un
lignaggio di un ominide più arcaico. Nel 2013, la sequenza di mtDNA
prelevata dal femore di un </span><span lang="it-IT"><i>Homo

proveniente dalla Grota Sima in Spagna è risultata essere simile a
quella di Denisova. </span></span></span>

<span style="color: orange;"><span style="font-family: "arial black" , sans-serif;"><span style="font-size: medium;">Per
decenni Lucy è stato il più famoso australopiteco mai scoperto nel
continente africano. Da oggi però ha un contendente: Little Foot, un
autentico fossile dei record appena svelato al mondo dai ricercatori
dell'Università di Witwatersrand, in Sudafrica. La scoperta è di
quelle capaci di cambiare le carte in tavola: non solo si tratta del
più antico progenitore dell’uomo mai portato alla luce nel Sud del
continente africano, ma anche dello scheletro di australopiteco più
completo mai scoperto.</span></span></span></div>

<span style="color: orange; font-family: "arial black" , sans-serif;"><span style="font-size: medium;">La
storia di Little Foot ha inizio nel 1994 nelle grotte di
Sterkfontein, circa 40 chilometri a Nord Ovest di Johannesburg, in
Sudafrica. È qui che il paleoantropologo </span></span><strong style="color: orange;"><span style="font-family: "arial black" , sans-serif;"><span style="font-size: medium;"><b><span style="background: #ffffff;">Ron
Clarke </span></b></span></span></strong><span style="color: orange; font-family: "arial black" , sans-serif;"><span style="font-size: medium;">rinvenne
i primi resti di questo scheletro di ominide: una manciata di
frammenti provenienti da una gamba, che fruttarono all’esemplare il
nomignolo di Little Foot, o piccolo piede.</span></span><br />
<span style="color: orange; font-family: "arial black" , sans-serif;"><span style="font-size: medium;">Avendo compreso di
trovarsi di fronte a una scoperta potenzialmente importante, Clark e
i suoi due assistenti,</span></span><strong style="color: orange;"><span style="font-family: "arial black" , sans-serif;"><span style="font-size: medium;"><b><span style="background: #ffffff;">Stephen

iniziarono una titanica operazione di scavo e catalogazione,
conclusasi solamente nel 2012, quando i ricercatori si resero conto
di aver portato alla luce lo scheletro praticamente completo di un
antico australopiteco.</span></span><span style="color: orange; font-family: "arial black" , sans-serif;"><span style="font-size: medium;">

<div align="LEFT" style="border: none; margin-bottom: 0cm; padding: 0cm;">
<span style="color: orange;"><span style="font-family: "arial black" , sans-serif;"><span style="font-size: medium;">Le
ossa appartengono a un lontano antenato dell'Homo Sapiens, vissuto
nell’area del suo ritrovamento circa 3,67 milioni di anni fa. Il
genere a cui appartiene è lo stesso di Lucy, ma i due fossili
rappresentano specie lievemente differenti, e Little Foot è più
antico di circa 500mila anni. Particolari che, a detta degli esperti,
lasciano ipotizzare che questi ominidi abitassero un’area del
continente africano ben più ampia di quanto si pensasse fino ad
oggi, vista la distanza tra l’attuale Etiopia – dove è stato
portato alla luce lo scheletro di Lucy – e il luogo del
ritrovamento di Little Foot.</span></span></span></div>

<br />
<span style="color: orange; font-family: "arial black" , sans-serif; font-size: medium;">Attualmente
i ricercatori sanno che si trattava di un ominide di sesso femminile,
probabilmente deceduto in seguito alla caduta che l'ha portata
all’interno delle grotte. La forma degli arti fa immaginare un
aspetto più simile a quello di un Homo Sapiens che a quello di una
scimmia, anche se Little Foot trascorreva ancora le sue notti al
riparo tra le chiome degli alberi.</span></div>

che Clark sta svolgendo proprio in queste settimane con l'assistenza
di un team di scienziati internazionale. Ma già oggi gli esperti
assicurano che i risultati, attesi già per il prossimo anno,
aiuteranno a gettare luce sull’evoluzione e l'origine della nostra

<b style="color: orange; font-family: Arial, Helvetica, sans-serif;">Su un versante
del Monte Cagno, che assieme al Monte Ocre forma una piccola dorsale
dell'Appennino abruzzese, è stata scoperta l'orma del più grande
dinosauro bipede vissuto in Italia, accompagnata da tracce di
dimensioni più contenute. Il gruppo di orme fu individuato una
decina di anni fa, nel 2006, ma soltanto grazie all'utilizzo delle
nuove tecnologie e il supporto di un drone i ricercatori del
Dipartimento di Scienze della Terra dell'Università Sapienza di Roma
e dell'Istituto Nazionale di Geofisica e Vulcanologia (INGV) sono
riusciti a studiarle nel dettaglio. Equipaggiando il drone con una
fotocamera ad alta risoluzione e utilizzando software di
fotogrammetria sono riusciti a ricostruirle in ambiente virtuale,
determinando diverse caratteristiche peculiari degli animali, che
tuttavia non è ancora possibile classificare con certezza.</b></div>

bipedi che nella maggior parte dei casi erano carnivori; a questo
gruppo appartengono specie note a chiunque come il tirannosauro e il
velociraptor, divenute celebri anche grazie alla serie di successo
Jurassic Park, firmata da Steven Spielberg e tratta dal romanzo del
compianto Michael Chricton. Il gruppo di impronte, site a circa 2mila
metri di quota e raggiungibili dopo un paio di ore di escursione
soltanto in estate e autunno, ovvero quando non vi è presenza di
neve, probabilmente è stato lasciato in tempi differenti e non con
un unico passaggio. Del resto ben poche specie avrebbero potuto
accompagnare il proprietario dell'orma più grande, lunga ben 135
centimetri.</b></span></div>

<span style="color: orange; font-family: Arial, Helvetica, sans-serif;"><b><br />Secondo il
paleontologo e geologo Paolo Citton della Sapienza, sarebbe stata
lasciata da un teropode gigantesco mentre si riposava in loco; la
posizione dell'orma e di una simile e parallela suggeriscono infatti
che l'animale fosse accovacciato. Tra i vari dettagli, oltre alle
tracce lasciate dalle dita, si notano quelle dei metatarsi e anche
quella dell'articolazione della caviglia. Le altre orme hanno invece
una forma molto più allungata e contenuta in dimensioni. Furono
lasciate tra i 125 e i 113 milioni di anni fa, nel Cretaceo
inferiore, ben prima del Tardo Cretaceo, che, com'è noto, fu teatro
dell'estinzione dei dinosauri. I dettagli della ricerca italiana sono
stati pubblicati sulla rivista specializzata Cretaceous Research
(Elsevier).<br /><br /><br />
