New hypothesis for evolution of different species

Bengaluru: Factors such as new environments, climates, competition, and habitats are known to lead to the formation of different species. However, the changes that individuals undergo during evolution are still an area of study. A recent scientific paper published in the journal Royal Society Open Science puts forth a new hypothesis that the rate of development of the brain as well as chemical changes in the nervous system can lead to the evolution of a new species.
