how does the creation of variation in species promote surviaval
Answers
Explanation:
Variations occur due to sexual reproduction and also due to inaccurate copying of DNA. Depending on the nature of variations, different individuals would have different kinds of advantages. For example, bacteria variants which can withstand heat have better chances to survive in a heat wave non-variant bacteria having no capacity to tolerate heat wave. Thus, variations in a population of a species help in survival of a species.
Answer
Some of the variations may be helpful to the organisms in the prevailing natural conditions. Organisms with such positive variations would survive. Over the period variations keep appearing in a species. The favorable variations are chosen by natural selection and promotes survival of the species.
Depending on the nature of variations different individuals would have different kinds of advantage e.g., Bacteria variants which can tolerate heat have better survival chances in heat wave in comparison to non-variant bacteria having no capacity to tolerate heat wave.
However not all variations are useful or beneficial.
