what`s the oldest DNA discovered
about 400,000 years old. this was DNA from a thigh-bone
found in the 'pit of bones' cave in the Atapuerca mountains
of northern Spain. the leg bone either belongs to an early
Neanderthal or possibly a member of the human Homoheidelbergsis.
these are both sister species to our own homosapiens but
H.heidelbergensis is the older species is the older species
probably the direct ancestor of both .
