In his book "The Origins of Species", Charles Darwin explored the relationship and progress of flora and fauna evolution in the Galapagos Islands and applied his theory to many fields. Darwin's book explains the theory that it evolved beyond generations through the process of natural selection, that is, the process by which the more desirable features of an organism are handed down to future generations. He wrote evidence in the HMS Beagle voyage of the 1830s and wrote his conclusion, including his travel, data collection and results analysis.
According to Darwin, the origin of the species has evolved into two different subspecies. Darwin has a different interpretation of the meaning of "origin of species". The way I understand is that the two groups of the same species are separated from each other in different environments. After several generations of development, these two groups developed different characteristics. Over time, more variants and new species have evolved. Assuming Darwin is correct, can humans evolve into two different species? For example, in the future, let's say a group colonizes Mars. For many generations, Martian humans will be different from humans on the planet. The difference between Earth humans and Martian humans is initially small, but in the future there may be two types of humans, the Earth's human beings and the Mars human beings.
