Even though rodents known as sugar gliders and flying squirrels are members of distinctly different groups of organisms and live
EleoNora [17]

Answer:

convergent evolution.

Explanation:

When organisms of distantly related species or groups are found in similar environmental conditions, they develop some similar features which are otherwise not present in their ancestral species. This is called convergent evolution. Convergent evolution also results in the development of similar traits in the distantly related organisms that are found in distantly located geographical regions having similar environmental conditions. Therefore, the presence of the same features in rodents and flying squirrels represent convergent evolution.

Complete the sentences to describe natural selection
Vikentia [17]
  1. The environment needs to change in order to natural selection to occur.

Reason:

Because, Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

2. Population has some genetic variations.

Reason:

Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by:

mutation and random mating between organisms

3. Nature select organism with specific traits to survive and reproduce.

Reason:

According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
