Question

The scientist who first gave the dynamic concept of species
A. Julian Huxley
B. Linnaeus
C. Lamarck
D, John Ray

Answer 1

The species is a central unit of classification and taxonomy of the organism, as well as of the biodiversity unit. A species is also defined as the largest group of organisms in which any two individuals of the appropriate sex or mating type can produce fertile offspring, typically by sexual reproduction.

Complete answer:
a) The democratic biologist and author Julian Huxley (1887-1975) helped to develop a new synthetic theory of evolution by natural selection and served as the first director of the United Nations Educational and Research Organisation (UNESCO).
b) Carl Linnaeus is renowned for his work on taxonomy, i.e, the study of the description, naming and classification of species (plants, animals, bacteria, fungi, etc.).
c) The complex definition of the species was introduced by Lamarck. According to this definition, 'Species are still changeable.' There are still shifts in the characters of the genus from one generation to the next. These shifts are referred to as evolution.
d) John Ray was a highly prominent English naturalist and botanist whose taxonomy contributions are considered to be groundbreaking and historic. In the field of botany, it is also well known for the development of species as the supreme taxonomy unit.
So, the correct answer is option C.

Note: The total number of species is estimated to be between 8 to 8.7 million. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs.
