According to static concept of species, species are unchangeable over the course of time and evolution. Given by Linnaeus on the basis of external morphology like Shape,size and color-All animals that are same in shape, size, colour belongs to same specles.

Static concept of species was put forward by Linnaeus.

Explanation:

Static concept of species is the idea that species are fixed and unchanging, and that they can be classified based on their physical characteristics. This concept was put forward by the Swedish botanist Carl Linnaeus in his work Systema Naturae, first published in 1735.

Linnaeus believed that each species was created by God with a fixed set of characteristics, and that these characteristics could be used to identify and classify different species. He developed a system of binomial nomenclature, which is still used today, to give each species a unique scientific name based on its physical characteristics.

Linnaeus' static concept of species was widely accepted for many years, but it was challenged by the theory of evolution put forward by Charles Darwin in the 19th century. Darwin's theory proposed that species evolved over time through natural selection, and that they were not fixed and unchanging.

Today, most scientists accept the theory of evolution and reject the static concept of species. They recognize that species are not fixed, but are constantly evolving and changing over time. However, Linnaeus' system of classification based on physical characteristics is still used as a basis for modern taxonomy, which is the science of classifying and naming living organisms.
