Question

C. Name at least two structural adaptations and two behavioral adaptations that humans have. How do these adaptation help human to survive?​

Answer 1

Explanation:

First, we will look at the structural, or physical adaptations, that help living organisms survive. Structural adaptations include such things as body color, body covering, beak type, and claw type.

Answer 2

Answer:

All organisms have adaptations that help them survive and thrive. Some adaptations are structural. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.

Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.

Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.

Bird For example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species. The longer beak helps the bird catch more food. Because the bird can catch more food, it is healthier than the other birds, lives longer and breeds more. The bird passes the gene for a longer beak on to its offspring. They also live longer and have more offspring and the gene continues to be inherited generation after generation.

Eventually the longer beak can be found in all of the species. This doesn't happen overnight. It takes thousands of years for a mutation to be found in an entire species.

Over time, animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.

The characteristics that help a species survive in an environment are passed on to future generations. Those characteristics that don't help the species survive slowly disappear.
