Evolution & Ecology TNReady Review

This is how your teacher feels if you got this question wrong.

Natural selection happens on a smaller scale, but over time it can cause evolution to occur.

Wallace & Darwin are best known for their work on evolution.

Rosalind Franklin took Photo 51, which led to the discovery of the double-helix shape of DNA.

Marie Curie was a physicist and chemist best known for studying radioactivity.

Gregor Mendel is known as the "Father of Genetics" for his work studying traits and heredity.

In evolutionary terms, "fitness" refers to an organism's ability to survive and reproduce. Since the predators prefer to eat the green beetles, they are less likely to survive (and therefore have a lower fitness). Since the brown beetles are surviving, they also have a greater chance of reproducing, so they would have a higher level of fitness in this scenario.
