Common ancestry of all species from "summary" of On the Origin of Species By Means of Natural Selection by Charles Darwin
The idea that all living beings have descended from a common ancestor holds immense implications for the study of biology. It is a concept that unites all species under a single tree of life, branching out into the diverse forms we see today. Through the process of natural selection, variations in individuals that are beneficial for survival and reproduction are passed down through generations, leading to the gradual change and adaptation of species over time. This theory of common ancestry provides a framework for understanding the interconnectedness of all living organisms. It explains the similarities and differences between species, highlighting the underlying genetic and evolutionary relationships that bind them together. By recognizing our shared history with other species, we can gain a deeper appreciation for the complex...
