Man’s Place In The Universe
Wallace was a pioneer in the world of Biogeography and was even far ahead of his time in terms of speaking to life on other planets. In his book “Man’s Place in the Universe,” he became the first biologist to make a serious attempt to claim or hypothesize the possibility that life could be on other planets. In particular, he wrote about Mars.
Today, we know Mars once had water, though we still don’t know if any life ever did. Other planets, however, have proof of plants, trees, etc. Some still living to this day! Their form of evolution and especially natural selection could differ. However, it is clear that both terms are universal, quite literally. In that no matter what, life will have to abide by these principles. In fact, humans have even shown that we evolve even as we enter space.
