Detailed explanation-1: -asexual reproduction. Summary: Evolutionary biologists have found that environment plays a key role in determining whether a species opts for sexual over asexual reproduction.

Detailed explanation-2: -Asexually reproducing organisms spend fewer resources for the same reproductive output, meaning their populations grow and expand faster than sexually reproducing ones. On the other hand, asexual populations have reduced genetic diversity and, hence, lower adaptability to changing environments.

Detailed explanation-3: -Something that reproduces asexually will have a difficult time adapting.

Detailed explanation-4: -2) If the environment is stable (unchanging), and a particular organism is very well adapted to it, asexual reproduction has an advantage over sexual reproduction. If however, the environment changes (as we know it usually does), then sexual reproduction is favored since it allows for new combinations of genes.
