A population of green frogs lives in a shallow pond in Altman. A few of the frogs have a random mutation that causes their skin pigment to be brown rather than green. Explain a scenario where this mutation could be just one of the normal variations of the frog color along with green as well.

"Look at these giraffe fossils over time! The necks are so much shorter millions of years ago! I wonder if over time the giraffes reaching for the higher leaves on the Acacia Trees caused the species to grow longer necks!!!"

Which of the following best describes natural selection?

In a population of beetles, some are green and some are brown. If birds prefer eating green beetles, what is likely to happen over time?

• The population will have more green beetles

• The population will have more brown beetles

• The population will remain the same

• The beetles will change color to avoid predation
