A change in allele frequencies over successive generations in a population signifies that some level of evolution is occurring.

apes_cladogram.jpg  Humans, chimpanzees, gorillas, and orangutans are members of a clade called the great apes, which shared a common ancestor about fifteen million years ago. Gibbons and siamangs comprise a clade called the lesser apes. Tree-branch lengths indicate elapsed time. Chimps and gorillas are humans’ closest relatives. If humans were removed from the great ape clade and placed in a different clade of their own, this would have the effect of making the phylogenetic tree of the great apes _____.
