Presentation transcript:

Do now activity Give an example of a variation in nature. Give an example of an animal adaptation. True/False: There are 3 factors that lead to evolution in a species. List all factors that lead to evolution in a species.

Section 5-4: artificial Selection Essential Question: How can a species be changed by its environment? Learning Target Explain the relationship between the factors of evolution and the adaptation of a species that results from competition for limited resources. Create a flow map that demonstrates the effect of an environmental change on a species. Section 5-4: artificial Selection

overview Artificial selection is when... Humans select which organisms get to reproduce.

Don’t forget to chunk your notes!

Artificial selection Nature Selection = All Variations Artificial Selection = Humans pick most useful variations.

Artificial selection Fat pigs. Dairy Cows. Fast Horses. For example, these are the animals that get to pass on their traits: Fat pigs. Dairy Cows. Fast Horses.

Artificial VS. natural Natural Selection: nature determines which organisms live on to reproduce.

Artificial VS. natural Artificial Selection: humans decide which organisms should reproduce the most.

Do Now Activity What is the difference between adaptation and variation? What is the definition of evolution? List all evidence that points towards evolution. How can competition help with carrying capacity? What is the difference between natural selection and artificial selection? How come variation among species is required for Survival of the Fittest?
