Question

Why is variation beneficial for species but not for individual​

Answer 1

Explanation:

The variation is important and beneficial for species as it allows a species to adapt to a changing environment. Only those who adopt the changes can survive in harsher conditions by adapting to the changes. For an individual, the variation doesn't matter in most of the conditions.

Answer 2

Variation is not essential for an individual because it doesn't help in the evolution. If an individual incorporates changes through gene mutation it result in health issues over a time period.
