The history of hominin evolution demonstrates ________.
A) unrelated traits (that is, characters of skulls and hips/feet) evolve together
B) unrelated traits can evolve at different rates
C) the decrease in rainfall favoured maintaining the ability to climb trees
D) the increase in rainfall favoured the ability to walk upright

Question

Quizplus · Accepted Answer

The history of hominin evolution demonstrates that unrelated traits can evolve at different rates. For example, the evolution of bipedalism (walking upright on two legs) was not necessarily accompanied by changes in other traits, such as skull features. This means that some traits can evolve more quickly than others, leading to a mosaic pattern of evolution in which different traits may evolve independently of one another.
