About this deal

A member of the Australopithecus afarensis left human-like footprints on volcanic ash in Laetoli, northern Tanzania, providing strong evidence of full-time bipedalism. Australopithecus afarensis lived between 3.9 and 2.9 million years ago, and is considered one of the earliest hominins—those species that developed and comprised the lineage of Homo and Homo 's closest relatives after the split from the line of the chimpanzees. The theory that there was a near-extinction event for early humans about 70,000 years ago. savannah hypothesis

The remains of the transitional man were discovered in the Pleistocene bed of East Africa. They were the makers of crudely chipped stone tools. This species of the human race represents an intermediate stage between the Australopithecus and Pithecanthropus erectus. The mean capacity of the brain was 680 c.c. Callaway, Ewen (2016). "Oldest ancient-human DNA details dawn of Neanderthals". Nature. 531 (7594): 296–86. Bibcode: 2016Natur.531..296C. doi: 10.1038/531286a. PMID 26983523. S2CID 4459329. Panderichthys is a 90–130cm (35–50in) long fish from the Late Devonian period (380 Mya). It has a large tetrapod-like head. Panderichthys exhibits features transitional between lobe-finned fishes and early tetrapods.Darwin grew up and lived in an age when slavery was still practised in many countries. Even where slavery had been abolished, many still regarded the different ‘races’ of humans as separate creations; white Europeans were considered the most advanced (by white Europeans). Many people though rejected these views, and Darwin was one of them. His family had a history of liberal thinking, and the young Darwin’s views were, at an early age, quite in line with these. Our evolutionary history is written into our genome. The human genome looks the way it does due to all genetic changes that affected our ancestors. The exact origin of modern humans has always been a topic of debate.

Catarrhini splits into 2 superfamilies, Old World monkeys (Cercopithecoidea) and apes ( Hominoidea). Human trichromatic color vision had its genetic origins in this period. Catarrhines lost the vomeronasal organ (or possibly reduced it to vestigial status). The therapsids had temporal fenestrae larger and more mammal-like than pelycosaurs, their teeth showed more serial differentiation, their gait was semi-erect and later forms had evolved a secondary palate. A secondary palate enables the animal to eat and breathe at the same time and is a sign of a more active, perhaps warm-blooded, way of life. [21] They had lost gastralia and, possibly, scales.Nicholas Wade (October 19, 2007). "Neanderthals Had Important Speech Gene, DNA Evidence Shows". The New York Times.
