    An early hominid, Homo erectus, depicted in this diorama from the American Museum of Natural History's Hall of Human Biology and Evolution, lived nearly 2 million years ago in the eastern Rift Valley of Africa.

Human Evolution Timeline - I see Homo Sapiens is not connected to or descended from any other human looking species on this timeline? Why is that? And how exactly did these species produce NEW genes to be able to grow the brain to a bigger size? Mutations and Duplications do NOT grow new genes with new functions.

Human Evolution (a likely model)

Humans are just the latest in a long line of hominid species that have emerged in the past six million years.

A New View of Evolution by sciencemag: This is a 1.77-million-year-old complete adult skull (braincase volume: 546 cubic centimeters) of early Homo from the site of Dmanisi, Georgia. Together with the fossilized bones of four additional individuals discovered in close proximity, the skull indicates that populations of early Homo comprised a wider range of morphological variation than traditionally assumed, which implies a single evolving lineage... #Science #Human_Evolution

Anthropologists say that a 1.8-million-year-old hominid skull unearthed in the Republic of Georgia shows that Homo habilis, Homo erectus, and Homo rudolfensis were all variations of a single species.

Homo neanderthalensis dates back only 28,000 to 200,000 years ago. It is not an ancestor of humans but a separate hominid species that lived simultaneously with humans for a while before extinction. Some scientists believe the 2 hominid species may have interbred. Evidence shows that Neanderthals may have dug graves for their dead, which marks the first of the hominids to do so.

What Makes Humans Special? by scientificamerican: HALLMARK TRAITS of the human body did not all arise anew in our species. Instead they emerged piecemeal in our forebears over millions of years. Many of these traits seem to have helped support two defining trends in our evolution: upright locomotion and tool use. #Infographic #Human_Body #Evolution
