The early evolution of higher apes and early ancestors of modern humans most closely resembles
A)a straight-line vine with one main trunk and many unsuccessful short branches,with only one or two forms coexisting at any one time.
B)two main trunks leading to apes or humans,and where each newly advanced species of Homo immediately eliminated any coexisting hominids.
C)a many-branched tree with all modern forms extending back relatively unchanged until reaching the common "missing link" at an origin about 33 million years ago.
D)a complex bush with many branches and perhaps as many as ten species of hominins 2 million years ago.
E)two streams,Australopithecus and Homo,that merge into one lineage leading to humans.
