Question

Why is variation beneficial to the species but not necessarily for the individual?

Answer 1

Heya mate
The answer of ur question is

♢ 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.

hope it helps

Answer 2

Dear Student,

● Variation is beneficial to the species but not necessarily for the individual because -

• Genetic variations help the organisms to adapt to changes taking place in the environment.
• This variations take place slowly over time and not singnificant between two consequtive generations.
• Also usually enevironmental changes dont occur suddenly, individuals dont need variations.
• But over a period of time conditions change in the surroundings (for example, global warming), only the fittest species adapting to these changes survive.
• Hence, variations are beneficial to species for the purpose of evolution.

Thanks dear. Hope this is helpful...
