Question

what factors could lead to the rise of new species?Explain any one on detail

Answer 1

natural selection, genetic drift, geographical isolation, etc. Geographical isolation -- It is caused by barriers such as mountain ranges, rivers and seas. It leads to reproductive isolation due to which there is no flow of genes between separated groups of population which ultimately results in specification.
