Like later hominins, it has teeth with thick molar enamel, but, unlike humans, it has distinctively apelike canine and premolar teeth.The case for its hominin status rests on the humanlike features of the femur.The foot is notably apelike with elongated toes and a fully divergent great toe for moving about in trees.Animal fossils, pollen, and other evidence associated with , which was discovered in northern Kenya near Lake Turkana at Kanapoi and Allia Bay.The curved finger and toe bones are likely evolutionary remnants left over from an apelike ancestor.While the upper limb is relatively long compared with the length of the lower limb, the spine exhibits humanlike curvatures, and the foot has a convergent great toe and strong arches as shown in modern humans.While the canine tooth is apelike in some respects, it does not exhibit the classic interlocking honing complex (where the inner side of the upper canine sharpens itself against the lower premolar [or bicuspid]).
Imagine what the world would be like today if they just figured out how to stick a wheel or four on it back then.
The first practical steam engine was patented in 1698 by Thomas Savery, but it wasn't until James Watt's patent in 1781 that it really became a useful product. We can thank Watt's engine for much of that, but we aren't concerned with something invented in the last few centuries …
not when the Greeks invented a working steam engine back in the 1st century CE.
Non-australopithecine members of the human lineage (hominins) include Identifying the earliest member of the human tribe (Hominini) is difficult because the predecessors of modern humans become increasingly apelike as the fossil record is followed back through time.
They resemble what would be expected in the common ancestor of humans and apes in that they possess a mix of human and ape traits.
The tibia (shinbone) exhibits anatomy at both the knee and ankle ends characteristic of later bipedal hominins.
