Team members led by paleontologist Mary Leakey stumbled upon animal tracks cemented in the volcanic ash in 1976, but it wasn’t until 1978 that Paul Abell joined Leakey’s team and found the 88ft (27m) long footprint trail referred to now as “The Laetoli Footprints,” which includes about 70 early human footprints.
It preserves previously unknown morphology, including moderately sized, mesiodistally long postcanine teeth.
The nearly complete mandible KNM-ER 60000 and mandibular fragment KNM-ER 62003 have a dental arcade that is short anteroposteriorly and flat across the front, with small incisors; these features are consistent with the arcade morphology of KNM-ER 1470 and KNM-ER 62000.
Writing for Scientific American, Kate Wong has a nice commentary on the story that includes several quotes from me, which I thought I could clarify and expand on a bit.
So, Leakey, Spoor and colleagues (as well as just about all of the other commentators I have seen) feel these new fossils provide additional evidence for multiple, concurrent species of Homo at the Pliocene-Pleistocene boundary (~1.6-2.0 million years ago). To explain, it helps to have a little historical perspective on the problem of early Homo.
The research adds to a growing body of evidence that runs counter to the popular perception that there was a linear evolution from early primates to modern humans. The skull was markedly different to any others from that time.
It had a relatively large brain and long flat face.
Here we report on three newly discovered fossils, aged between 1.78 and 1.95 million years (Myr) old, that clarify the anatomy and taxonomic status of KNM-ER 1470.
KNM-ER 62000, a well-preserved face of a late juvenile hominin, closely resembles KNM-ER 1470 but is notably smaller.
africanus, in particular) and already known Asian (and to a less extent, African) Homo erectus such as those from China and Java.
Philip Tobias, controversially, gave them the designation Homo habilis and placed them as a transitional species.
Researchers studying fossils from northern Kenya have identified a new species of human that lived two million years ago.Tags: Adult Dating, affair dating, sex dating
