According to Darwin, the organic evolution is due to :
Updated On: May 1, 2024
- Reduced feeding efficiency in one species due to the presence of interfering species
- Intraspecific competition
- Interspecific competition
- Competition within closely related species
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Darwin stated that, the organic evolution is due to interspecific competition. It is the competition between members of different species. Intraspecific competition occurs amongst members of the same species for obtaining optimum amounts of their food, shelter, mate, water, light, etc. Closely related species if compete cannot cause evolution. Reduced feeding efficiency in one species due to the presence of interfering species is due to strugle for existence.

According to evolutionary theory, every evolutionary change involves the substitution of a new gene for the old one and the new allele arises from the old one. Continuous accumulation of changes in the DNA coding for proteins leads to evolutionary differences. The chemical composition of DNA is basically the same in all living beings, except for differences in the sequence of nitrogenous bases. Given below are percentage relative similarities between human DNA and DNA of other vertebrates:

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
