Most animal and plant species we see in the fossil record are extinct, or no longer living. In fact, of all the species that ever lived, 98% are extinct. Animals and plants become extinct over time as a result of natural processes. Their habitat might change or a disease might wipe out a species.
The trend of extinction and difference in body parts in the complexity of life
over time is seen through the fossil record
Fossils refers to remains of living organisms which have been replaced in the form of rock particles due to its presence in the soil for a long period of time.
The fossils contain an understanding of the structures and characteristics
the animals had which is then compared to its present structures. This helps
to explain how the animals adapted to climate change through changes in
the structure, shape of parts of the body.
It also tells the location of animals and their different movements in response to challenges faced in the ecosystem.

What benefit does an organism gain by only using this method of reproduction?
Explanation:
In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. On the other hand, the rapid rates of asexual reproduction may allow for a speedy response to environmental changes if individuals have mutations. An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce.
