Methods dating human fossils
age: 11.9 mya fossils found: nearly complete cranium, much of torso, arms and legs, parts of hands adaptations: small monkey-like hands, wider pelvis than predecessors, expanded rib cage for climbing location found: Spain notes: may be common ancestor of chimpanzees and humans in the human evolution timeline; probably walked semi-upright using forelimbs age: 6 – 7 mya fossils found: nearly complete cranium, some fragments lower jaw & teeth brain size: 350 cc adaptations: ape-like, including small brain size, hominid features: brow ridges, small canine teeth location found: Chad, Central Africa notes: close to common ancestor of chimpanzees and humans in the human evolution timeline; unlikely to be bipedal age: c.6 mya brain size: no cranium found fossils found: 13 fossils; partial femur, bits of jaw and teeth adaptations: unknown location found: Kenya, Africa notes: some indications of bipedality, but evidence is scant age: 5.8 – 4.4 mya brain size: approx.Nor indeed why the marine creatures were somehow 'drowned' by the flood.The rejection of dating by religious fundamentalists is easier for them to make, but harder for them to demonstrate.Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.
Hominid Species : from Describes 18 hominid & earlier species.
- Human Evolution Timeline Hominid Clade Tree showing an example of uncertainty of arrangement. Unfortunately, it is scattered among many sources, some of the best of which -- science journals -- require costly subscriptions to read.
It is regrettable also that most of the photographic evidence that is web-available is limited to skulls.
Although some species of fossil hominids are today represented by up to 500 specimens, for many there are but a few -- not enough, and not complete enough in some cases, to be certain as to the position within our family tree.
So there is debate within paleoanthropology about the matter -- healthy debate that requires more evidence before consensus is reached on all points.
ASTEROIDS: Scientists have discovered a very large asteroid impact site in Antarctica.
