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.
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
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
Fossils from Northern Kenya show that a new species of human lived two million years ago, researchers say. Anthropologists have discovered three human fossils that are between 1.78 and 1.95 million years old. The specimens are of a face and two jawbones with teeth.
