The Origin of Humans Is Surprisingly Complicated



Some explanation is forthcoming in a new book to be out soon.  But anthropologists and Darwinists, will not like it and might leave bad reviews on my book. So, all five star reviews are welcomed and appreciated! lol

The latest molecular analyses and fossil finds suggest that the story of human evolution is far more complex—and more interesting—than anyone imagined

Many kinds of archaic humans walked the planet at the same time. How did Homo sapiens come to be the last species standing?
HUMAN FAMILY TREE used to be a scraggly thing. With relatively few fossils to work from, scientists' best guess was that they could all be assigned to just two lineages, one of which went extinct and the other of which ultimately gave rise to us. Discoveries made over the past few decades have revealed a far more luxuriant tree, however—one abounding with branches and twigs that eventually petered out. This newfound diversity paints a much more interesting picture of our origins but makes sorting our ancestors from the evolutionary dead ends all the more challenging, as paleoanthropologist Bernard Wood explains in the pages that follow.

So what do you think?” said Lee Berger. He had just opened the lids of two big wooden boxes, each containing the carefully laid out fossilized bones of a humanlike skeleton from Malapa, South Africa. These two individuals, who had drawn their last breath two million years ago, had created quite a stir. Most fossils are “isolated” finds—a jawbone here, a foot bone there. Scientists then have to figure out whether the pieces belong to the same individual. Think of walking down the highway and finding parts of cars—a broken fender here, part of a transmission there. Do they belong to the same model, or even make, of car? Or might they not have come from a car at all but from a pickup?


In contrast, the skeletons from Malapa, though not complete, are intact enough to reduce the possibility of random commingling. Like “Lucy” (unearthed in Ethiopia in 1974) and the “Turkana Boy” (found in Kenya in 1984), they have so much more to say than individual fossils. But they had made the headlines not because they are complete and so well preserved but because Berger, a paleoanthropologist at the University of the Witwatersrand, Johannesburg, had suggested that the individuals were part of a population that was directly ancestral to our own genus, Homo.http://www.scientificamerican.com/article/the-latest-fossil-finds-make-the-puzzle-of-human-evolution-harder-than-ever-to-solve/
