In fact, the number of branches our evolutionary tree, and also the length of time, has nearly doubled since the famed ‘Lucy’ fossil skeleton was discovered in 1974!
There were periods in the past when three or four early human species lived at the same time, even in the same place.
The assays were run separately by several independent laboratories, thus supporting the validity of the results.
This video is part 4 of 13 in the Human Paleontology series.Initially, the researchers who discovered and analyzed the skeletal remains of at least 15 individuals of this previously unknown species, which were found deep in a cave located roughly 50 km (30 miles) northwest of Johannesburg, South Africa, thought that it was a very early member of the genus .Based on evolutionarily primitive characteristics, including a small brain, but also some more progressive features, such as long leg bones, the scientists thought that the fossils could date to as much as 2.5 million years ago. However, the lack of an independent dating method was problematic.The following tables give a brief overview of several notable hominin fossil finds relating to human evolution beginning with the formation of the Hominini tribe in the late Miocene (roughly 6 million years ago).As there are thousands of fossils, mostly fragmentary, often consisting of single bones or isolated teeth with complete skulls and skeletons rare, this overview is not complete, but does show some of the most important finds.
