Evolutions

Which of the following statements accurately describes the role of mutations in evolution

• Mutations are the raw material for evolution, but most mutations do not result in evolution.

• Most mutations result in a species becoming more dangerous or aggressive.

• An organisms can decide to mutate if the environment makes a mutation necessary for survival.

• Mutations are almost always beneficial for an individual.

The palmarus longus tendon, pictured here, no longer serves a purpose in humans, but provides evidence of our species descendance from tree-dwelling ancestors. The palmarus longus tendon is an example of:

• a vestigial structure

• a homologous structure

• bipedalism

• convergent evolution
