A fossil record is evidence for evolution because you can compare the fossiles to see the difference. You can tell how "survival of the fittest" played a part, and what characteristics the species had to help them survive in their environment.

Answer:

Fossils are the dead remnants of ancients flora and fauna that are buried millions of years ago. These fossils are found to be present in the sedimentary rocks. These fossils are very important in order to understand the evolutionary pattern of the organisms, their food habitat and also the past climatic and environmental conditions.

These fossils play a key role in determining the way the organisms have undergone evolution. The earliest fossil found on earth belongs to the rocks of Western Australia that dates back to about 3.5 billion years. The fossils belonging to the pre-historical time were very simple, and the fossils that belong to the recent ages are very complex. This marks the pattern of how evolution has taken place. The earth has experienced episodic mass extinction events that wiped out more than 90% of the living species on earth, but only those organisms survived which were able to adapt to the changing environmental conditions.

These organisms have undergone evolution with the gradual increase in time, forming more, new and complex types of living species. Some of the fossils are also found that records the entire evolution pattern. For example, the evolutionary pattern of the horse has a complete record.

Explanation:

The huge diversity in Namibia’s eco system made it the richest place of South Africa in terms of species that this place have. This ecosystem has endemic species with a number of 14 in it.

To organise these species three biotic sectors in Namibia are utilized, they are- The Southern Savanna, the Southwest Arid and Dessert of Namib.

The wetland ecosystem of Arid is important for many species and the mammals also. The elephant of desert and the black rhinos belongs to the Namibia Dessert ecosystem.

A geneticist discovers that two different proteins are encoded by the same gene. One protein has 56 amino acids, and the other h
sergeinik [125]

Answer:

The same gene encodes both proteins by using different combinations of exons in the pre‑mRNA via alternative splicing.

Explanation:

According to the question, two different proteins (one with 56 amino acids and the other with 82 amino acids) are found to be encoded by the same gene. This is possible due to a process called ALTERNATIVE SPLICING.

Alternative splicing is a phenomenon whereby the protein-coding region of a gene called EXON is manipulated in such a way that variety of proteins emanate from a single gene. This manipulation includes the removal or inclusion of EXONS in the gene, so as to give rise to different combinations of mRNA, hence, different proteins will be translated from the different mRNA from the same gene.

In this case, exons were removed from one mRNA to have lesser amino acids (56) in the translated protein while exons were included in the other mRNA to have more amino acids (82).
