Answer:
<u>Natural selection leads to evolutionary change </u>
Explanation:
- Natural selection is a process by which the species adapt to their environment. Thus individuals have a better chance of survival and evolution and transfer their traits to offsprings.
- As the process of evolution cannot take place without genetic mutation or diversification of genetic buildup. The occurrence of repeatedly branching events take place in which new species splits from a common ancestor producing a multi-level tree.
- For example, in the event of climate change, those species capable of tolerating the temperature will not die as compared to those which are not capable of tolerating and thus will not reproduce.
- If the same process is repeated over millions of years of the time the population will get adapted to their new climate and develop genes that combat these drastic changes.
Answer:
d. They provide complete records of every fossil lineage.
Explanation:
- The transitional fossil record shows the ancestral forms and the descendants thus referred to as the transitional form and thus provides evidence over the changes in the fossil lineages.
- The transitional forms are seen as falling between the various groups in the term of the anatomy and have a mixture of the characters in terms of outside and the inside of the fossil records.
- <u>In 1859 Charles darwin published the book on the Origin Of the species and he perceived the lack of the transitional fossils and gave the example of this transnational fossil as the tetrapods, fish birds ad the dinosaurs.
