Evolution/ Natural Selection
background
Evolution Change(genetic) in a population or species of living organisms over time.
How do populations evolve? The INDIVIDUALS within a population cannot evolve (they will someday die with the same genes with which they were born). Individuals can only accumulate adaptationsthat help them survive in the environment. Evolution takes a long time, spanning several generations, to happen.

Charles DarwinWho is he?
Charles Darwin is best known for his work as a naturalist, developing a theory of evolution to explain biological change. He described evolution as “descent with modification.” Proposed natural selection as the natural force that drives evolution Organisms with more favorable traits have an advantage within a local environment (white snow hare). They produce more offspring and pass down their favorable genes to their descendants. Example: Overtime gazelles may become more aware and alert. Not all of the gazelles have the same genes so not all have the chance to be passed down. This is because the slower, non-eyesight genes are unable to produce because they are more likely to die before they get the chance to. The population will evolve, even though the individual gazelles don’t “Differential Reproductive Success.” The majority will be stronger and have better eyesight than those before. |
