Many species can reproduce either asexually or sexually. Explain what you think might be the evolutionary significance of the switch from asexual to sexual reproduction that occurs in some organisms when the environment becomes unfavorable.

Asexual reproduction sidesteps the need for fertilization and makes every individual--not just females--capable of reproduction. That allows for very rapid population growth. But the capability of very rapid population growth comes at the expense of genetic variation, and genetic variation greatly increases the chance that at least some offspring will be adapted to a changing environment.

Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only. Asexual reproduction is the primary form of reproduction for single-celled organisms such as bacteria. Many plants and fungi reproduce asexually as well. Sexual reproduction is a process that creates a new organism by combining the genetic material of two organisms. One of the most widely accepted explanations for the advantage of sex lies in the creation of genetic variation, which provides a
significant increase in the fitness of the offspring.

With asexual reproduction, mutations can only be passed on.
Sexual reproduction allows mutations that happened to different individuals to be combined in a new individual

Propagation of the species,,really that simple.
Nothing to show an evolutionary change. Adaptation would be more like it.

The answer is to introduce variety. Only a small amount of variance can occur when working with a single genome’s worth of DNA. This means evolution comes slow to larger asexual organisms that reproduce at a slower rate.

I think evolution still doesn't actually work even though they try to say, much like biblical literalism!
