> This does not necessarily mean any new genetic material or "nature responding". But this is exactly how evolution works. There are always mutations in every generation, and sometimes those mutations are beneficial. These genes are being selected by the organism's environment, and if the environment changes, then the genes that are selected will be different. That is "nature responding". Elephants without tusks (or very small ones) are more likely to survive and produce offspring. |
