Question

Being all mammals, whales, dolphins, bats, monkeys, and horses have some familiar critical characters, but they also show conspicuous differences. This is due to the phenomenon of:
a. Normalization
b. Genetic drift
c. Convergence
d. Divergence

Answer 1

The mammals are the animals that are typically characterized by the existence of mammary glands, which in females generate milk for feeding their younger ones. The neocortex (it is a region of the brain), fur or hair, and three middle ear bones are present in this group of animals. The characters which are mentioned above can help to differentiate the mammals from reptiles and birds. We can say that human beings also come under the category of mammals.

Complete answer:
- The procedure of tracing back two or more species to their common ancestor is called the evolution of divergence. Thus, we can say that these animals become a different species to their lineages and what was once one class has deviated into two.
- However, when the species have different ancestral origins but have similar features to develop, then evolution is called Convergent evolution.
- An organized method of disintegrating tablets to eliminate data severance (repetition) is called Normalization. It can also eliminate undesirable characteristics like Supplement, Apprise, and Deletion Anomalies.
- One can define the Genetic drift as a progression mechanism in which the allele rate of recurrence of an inhabitant changes over compeers due to accidents (sampling error).

Hence, the correct answer is option (D).

Note: One can say that the word mammal is obtained from the Latin word 'mamma,' which has the meaning of breast. We can define the group of mammals, the vertebrate animals constituting the class Mammalia. The organisms are said to diverge in the late Carboniferous; we say this was approximately 300 million years ago.
