Question

Variation is beneficial to the species but not necessarily for the individual', give 3 reasons 2 justify it.

Answer 1

• Variation is beneficial for the existence of the species because they play an important role in the adaption to survive in the changing conditions.

• Variation is not essential for an individual because it doesn’t help in the evolution of a human being or a person.

• If an individual incorporates changes through gene mutation, it may result in health issues over a period of time.

Answer 2

Variations are beneficial to the species than individual because sometimes for a species, the environmental conditions change so drastically that their survival becomes difficult. For example, if the temperature of water increases suddenly, then most of the bacteria living in that water would die. Only few variants that are resistant to heat would be able to survive. However, if these variants were not there, then the entire species of bacteria would have been destroyed. Thus, these variants help in the survival of the species. However, all variations are not necessarily beneficial for the individual organisms.
