Question

According to the modern synthetic theory, the unit of evolution is a/an
A. Individual
B. Population
C. Species
D. Genus

Answer 1

Hint: The modern synthetic theory of evolution is a result of the works of several scientists on different kinds of communities.

Step by step answer:
The modern synthetic theory is a culmination of the works of many legendary evolutionary biologists like T. Dobzhansky, J. B. S. Haldane, Fisher, Wright, and Ernst Mayer. These scientists put forward their theories from 1930 to 1940. Their works were merged with that of Darwin and Mendel to create a unified theory. Thus, it is also known as the Unified theory of the Evolution of Neo-Darwinism.
The modern synthetic theory of evolution is used to describe evolution in terms of the genetic changes that occur in a population. These genetic changes cause the formation of any new species. It also explains the terms like genetic population or Mendelian population, gene pool, and the gene frequency, which are susceptible to Evolution.
The modern synthetic evolution theory emphasized on the genetics of evolution. Based on that it came up with a new definition of evolution as, ‘the changes occurring in the allele frequencies within the populations.
Thus, the modern synthetic theory of evolution is the population.

Hence, the correct answer is option (B)

Note: The factors of the modern synthetic theory of evolution are recombination or variation, mutation, heredity, natural selection, isolation. It is interesting to note that all these above factors are seen in the population.
