Principles of Evolution – Selection and Time
Selection is where the big part comes up. A species might develop something very useful through inherited means. These genes allow them to survive a lot better, which means even more species can be produced by that individual. This will then create offspring that, like their parent, also inherited useful survival tools. They will then pass on their useful genes, which will eventually lead to a population of long-lasting and impressive members of a species.
Time is simply the period when a species will develop all of its key survival skills and/or abilities. Some changes that are easy to make could take days to adapt to, while others take millions of years. The most successful of the species will pass on their genes to create more successful members of their species, and so on. It is also key to mention that even if a species develops a lot of key evolutionary traits over a long period of time, it is possible that it too may one day be unable to adapt. This will, in turn, make a once very adaptable line into a useless member of a species that needed them to get where they are today. That’s the sad part about evolution, you either adapt or you die off.
