A giraffe has a long neck and tongue to be able to reach the Acacia leaves in the tall trees. Lamarck believed this was caused by them stretching their necks to reach the leaves, over time causing them to have longer necks. What is actually the cause?
Natural selection, evolution
Over time, a random mutation caused giraffes to have a longer neck. This allowed them to reach more food and be more successful at reproduction. The trait for a longer neck was passed down until all of the individuals had a longer neck.

Explain what happened with the rock pocket mice.
Where could you find dark mice? Light mice? What caused the differences?
Dark mice on lava flows, light mice on sand. A random mutation caused a darker fur color.

What would happen if there was no variation in a species?
They would go extinct if their environment changed or if they came in contact with a disease they weren't protected from.

As we learned in the video, tigers are orange with black stripes because the species of deer they primarily eat do not have the color receptors to be able to distinguish orange and green-causing the cats to appear gray like the surrounding foliage. However, if this same tiger was placed in an environment in the desert it would not be fit enough to survive the intense heat.
What is this known as?
A. Survival of the fittest

C. Natural Variation
D. Artificial Selection

"While there are many edible plants that can be foraged in the wild (i.e. asparagus, berries, onions, etc.), broccoli is not one of them. Broccoli is in fact a human invention. It is not known exactly how many years ago broccoli was created, but it is believed that early varieties of this plant were cultivated in the Mediterranean region during the Roman Empire in the 6th century BCE."
The excerpt above is showing an example of how humans choose the desirable traits instead of nature. What is this known as?

Explain how the fossil record shows evidence of evolution.
Fossils show modern species resemble ancient species.
They also reveal that some species have changed very little.
The fossil record is an important source of information for determining the ancestry of organisms and the patterns of evolution.

Explain why you need to finish all of the antibiotics if you have a bacterial infection.
Natural variation causes some of the bacteria to be more resistant to the antibiotic. If you do not finish the prescription, you are only leaving the stronger bacteria to survive and reproduce. This eventually causes certain antibiotics to not be an effective treatment.
