In evolution, why is it important that individuals vary from each other?
a. variation allows some individuals to do better than others, so those variations are selected for.
b. if variations or mutations are extreme enough, new species can result.
c. variations are important because individuals have to change through time.
d. variations are important because they're inherited.
e. variation gives every individual an equal chance of surviving so they can be selected for.

D. Variations are important because they're inherited.

Explanation:

A. False

Not all variations are just beneficial, there are variations that can be harmful, leading natural selection to eliminate these individuals.

B. False

Without some environmental pressure, that is, any change that drives the selection of an individual, mutation alone cannot generate a new individual. If this mutation is not selected as "beneficial" and is not passed on to future generations, this mutation will disappear in that individual.

C. False

Not necessarily. Genetic variations occur at random, so those species that survive are selected and able to adapt.

E. False

It does not give an equal chance of surviving.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
