Due to huge effect use of Drought the population of animal get extinct.
Explanation:
Droughts can have a severe impact on the extinction of animal populations, specifically in Arid and Semi environments. Different type of climate changes can accelerate the dying of particular species or animal population.
For extinction of population and also species Droughts play vital role. Droughts are one of such severe climatic change that leads to the extinction of species. Some life traits of specific Species make it vulnerable to drought.
The RNA world hypothesis states that the earlier life-forms had relied only on RNA (Ribonucleic Acid) for the purpose of catalyzing the chemical reactions, and storing the genetic information. This hypothesis was proposed by Leslie Orgel, Carl Woese, and Francis Crick.
This hypothesis states that long before the living forms evolved to use DNA as the genetic storage material, the RNA molecules served the purpose of both storing the genetic information and carrying out catalysis, but because of its instability, DNA evolved.
Hence, the answer is RNA world hypothesis.
