Believed to be 4.5 billion years old. Thought to have had a very anaerobic atmosphere. Earliest organisms were able to survive primitive environments. Prokaryotes that resemble today’s bacteria. G7- I can list examples of changes in genetic traits due to natural and manmade influences. What is Natural Selection?. Write it on your white board. Which of the following is an example of Natural Selection?. What is “Natural Selection”?. No cheating!!. You must get 20 beans to survive.

Within an individual’s lifetime, it cannot evolve a new phenotype by natural selection in response to its environment.. Natural selection acts on the range of phenotypes in a population.. Just like all individuals make up a population, all of the genes of the population’s individuals make up the population’s genes. 3 Mechanisms for selection and an introduction to . Hardy-Weinberg.
