Question

Quizplus · Accepted Answer

The phylogeny depicted in the given figure is rooted. The gibbons and siamangs are considered an outgroup of the great apes. Chimps and humans are the closest extant sister taxa depicted here, indicating a close evolutionary relationship. However, phylogenies are not absolute and can be subject to error due to various factors. The last common ancestor of the great apes is estimated to have lived about 14 million years ago. Therefore, options 1, 2, 3, and 5 are correct. Option 4 is incorrect because no phylogeny is without error.
