Question

Variations provide a range of
traits
within a population. When the environment changes, individuals with certain variations may possess traits that are
suited to the new conditions. These individuals have a
chance of surviving and
, and passing on their beneficial traits to future generations.

Answer 1

This process, known as natural selection, drives evolution by selecting for traits that increase the likelihood of survival and reproduction in a given environment. Over time, these beneficial traits become more common in the population, leading to adaptation and evolution.Variation also plays a key role in genetic diversity, which is essential for a population's ability to adapt to changing environments. Genetic diversity ensures that there is a pool of different traits within a population, increasing the likelihood that some individuals will have traits that are well-suited to the new conditions. By preserving genetic diversity, populations are better able to respond to environmental challenges and avoid the negative consequences of inbreeding or genetic bottlenecks.
