eaten?

4) What does the word “evolution” mean?

Things in nature look the way they do for a reason. Organisms that have an advantage will survive. Other organisms will go extinct.

In nature there are 2 keys to survival: gaining energy and reproducing.

Warm Up 30 (5 questions)1) Explain how this diagram illustrates evolution?

2) A reintroduced population of wolves in a national park is 90% grey and 10% black, consistent with the wolf population in other regions. After several generations in isolation, the national park’s wolf population is 60% grey and 40% black. The wolf population has likely experiencedA. natural selection.B. genetic drift.C. mutations.D. migration.

3) How is the fish on the bottom an example of evolution by mutation?

4) Explain resistance.

2) Why does biodiversity increase as latitude decreases (closer to equator)?

Yesterday You Learned… 1) There is a huge diversity of life on Earth that

is critical to all species.2) We call that variety of life BIODIVERSITY.3) There are 3 types: ecosystem, genetic and

species diversity.4) Biodiversity is important for: food webs to

function, medical reasons, ethical reasons and more
