This time period also brought advances in architecture and art, including the invention of the potter’s wheel, and textiles—clothing consisted of mostly wool items such as skirts, kilts, tunics and cloaks. ), metalworking advances were made, as bronze, a copper and tin alloy, was discovered. Haikouichthys and Myllokunmingia are examples of these jawless fish, or Agnatha. Australopithecines appear. Australopithecines have been found in savannah environments; they probably developed their diet to include scavenged meat. In archaeology and anthropology, prehistory is subdivided around the three-age system, this list includes the use of the three-age system as well as a number of various designation used in reference to sub-ages within the traditional three.. Primatomorpha is a subdivision of Euarchonta including primates and their ancestral stem-primates Plesiadapiformes.

[72][73], Chronological outline of major events in the development of the human species. A member of the Australopithecus afarensis left human-like footprints on volcanic ash in Laetoli, northern Tanzania, providing strong evidence of full-time bipedalism. The timeline of human history begins between 160,000 and 195,000 years ago with early modern humans, beginning with early periods, such as the Mesolithic and Neolithic. Now used for weapons and tools, the harder metal replaced its stone predecessors, and helped spark innovations including the ox-drawn plow and the wheel. H. erectus is the first known species to develop control of fire, by about 1.5 Ma. All regions . They also fished and collected berries, fruit and nuts. Most known animal phyla appeared in the fossil record as marine species during the Cambrian explosion. [70], Extinction of late surviving archaic humans at the beginning of the Holocene (12 ka).

Ancient History – 3600 BCE – 500 CE. They used polished hand axes, adzes for ploughing and tilling the land and started to settle in the plains. "These possibly transitional fossils have been much studied, among them, "In many respects, the pelycosaurs are intermediate between the reptiles and mammals", "Thrinaxodon, like any fossil, should be thought of as a cousin of our ancestor, not the ancestor itself.

Accelerated divergence due to selection pressures in populations participating in the Neolithic Revolution after 12 ka, e.g. Advancements were made not only in tools but also in farming, home construction and art, including pottery, sewing and weaving. Homo habilis, although significantly different of anatomy and physiology, is thought to be the ancestor of Homo ergaster, or African Homo erectus; but it is also known to have coexisted with H. erectus for almost half a million years (until about 1.5 Ma). 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). Ancient Greece 3300 BC - 31 BC. Primitive tetrapods developed from a lobe-finned fish (an "osteolepid Sarcopterygian"), with a two-lobed brain in a flattened skull, a wide mouth and a short snout, whose upward-facing eyes show that it was a bottom-dweller, and which had already developed adaptations of fins with fleshy bases and bones.
