<u>Answer</u>:
Vestigial organs are those organs that were present in the past ancestors but absent in their present generations. Vestigial organs are not leftover of evolution because they are evolved to perform a different function.
<u>Explanation</u>:
For example, an appendix is considered as a vestigial organ but it helps in storing good bacteria and plays a vital role in the immune system. These vestigial organs are the product of changing the environment and adaptation to the changing environment. Due to natural selection some specific traits have been passed down to generations which helped the animals to survive in those conditions. The other examples of vestigial organs are wisdom teeth coccyx, tonsils, several genes in the chromosomes and our hair.
Answer:
If the average temperatures of temperate forests fell by about 25ºC during the period of 1500 years, the natural modification of the animals that would be favored would be that which allows an adaptation to the new climatic circumstances by the fauna of said forests, that is , to the notable drop in temperature. Thus, for example, animals would develop more voluminous furs, which would allow them to heat their bodies in a better way.
Behavioural adaptations are learned or inherited behaviours that help organisms to survive, for example, the sounds made by whales allow them to communicate, navigate and hunt prey. Crab larvae use sounds to help them find suitable habitats so they can settle and metamorphose (change into an adult form).
