Document Summary

Natural selection and adaptation: specific definitions of that, particularly in the context of biodiversity. Biodiversity crisis losing it at an extremely rapid rate. Life on earth is very diverse and ubiquitous: it is everywhere. There was an ancestor at the base of the tree and life diverged from there. Natural selection: one of the main drivers of the diversification of life, idea that traits that enhance survival and reproduction persist in populations, populations evolve over time, populations may diverge and form new species. Evolution proposed as an idea by charles darwin. Not the only one: wallace, but darwin published first. These two simple statements dramatically changed science and our view of human beings in the natural world: still controversial (for some reason) Change in the genetic composition of a population over time. When darwin was writing, he did not know about genetics but he did understand that offspring tend to resemble their parents.
