The individuals whose descendants would become Platyrrhini are conjectured to have migrated to South America either on a raft of vegetation or via a land bridge (the hypothesis now favored[25]). [48] Some fresh water lobe-finned fish (Sarcopterygii) develop legs and give rise to the Tetrapoda. Proconsul africanus is a possible ancestor of both great and lesser apes, including humans.

Analyses of Australopithecus africanus lower vertebrae suggests that these bones changed in females to support bipedalism even during pregnancy. The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4.2 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period. [44][45], Solidified footprints dated to about 350 ka and associated with H. heidelbergensis were found in southern Italy in 2003. However, the fossil record indicates that they left no descendants after the end of the Devonian and are less closely related to living bony fishes than sharks are. They cooked their prey, including woolly mammoths, deer and bison, using controlled fire. "Reassessing hominoid phylogeny: Evaluating congruence in the morphological and temporal data". Jul 4, 2012.

One subgroup of therapsids, the cynodonts, evolved more mammal-like characteristics. H. habilis is intermediate between Australopithecus afarensis and H. erectus, and there have been suggestions to re-classify it within genus Australopithecus, as Australopithecus habilis. Australopithecines appear. Bilateria/Triploblasts, Nephrozoa (555 Ma), last common ancestor of protostomes (including the arthropod [insect, crustacean] and platyzoan [flatworms] lineages) and the deuterostomes (including the vertebrate [human] lineage). Modern human presence in Southern Africa and West Africa. Prisma/Universal Images Group/Getty Images. It is thought that A. afarensis was ancestral to both the genus Australopithecus and the genus Homo. From Eucynodontia (cynodonts) came the first mammals. Tiktaalik is a genus of sarcopterygian (lobe-finned) fishes from the late Devonian with many tetrapod-like features. Acorn worms have a gill-like structure used for breathing, a structure similar to that of primitive fish. 401 Thucydides, Greek historian, leaves account of "Golden Age of Pericles" and Peloponnesian War at his death (History of the Peloponnesian War). Universal History Archive/Universal Images Group/Getty Images. New Kingdom (Egypt) 1550 BC - 1070 BC. 2. However, genetic evidence from the Sima de los Huesos fossils published in 2016 seems to suggest that H. heidelbergensis in its entirety should be included in the Neanderthal lineage, as "pre-Neanderthal" or "early Neanderthal", while the divergence time between the Neanderthal and modern lineages has been pushed back to before the emergence of H. heidelbergensis, to about 600,000 to 800,000 years ago, the approximate age of Homo antecessor. 30 (4): 614. The earliest mammal-like reptiles are the pelycosaurs.

Australopithecines have been found in savannah environments; they probably developed their diet to include scavenged meat. 'In an experiment, one needs to hold all else constant, apart from the aspect of interest. The first vertebrates appear: the ostracoderms, jawless fish related to present-day lampreys and hagfishes. Viewed zoologically, we humans are Homo sapiens, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
