Who is Charles Darwin?

True or False: Humans and chimpanzees have similar DNA. Therefore, chimps can evolve into humans.
FALSE!!!
The first part is true but humans and chimps have separated on the evolutionary tree thousands of years ago!

What two factors INCREASE the chance of a species survival?
(think about why humans are NOT likely to become extinct any time soon)
What are variation/diversity and population size?
200
What causes NEW adaptations and traits to arise?
What are mutations!

Darwin's main conclusion after finding birds with differently shaped beaks was:
1. Any bird can have any shape beak
2. The birds have the best beak for them to survive in their environment
3. Bird's beaks have nothing to do with how well eat
4. Bird's beaks can change every generation

In the early stages of development, the embryos of birds and reptiles resemble each other in many ways. This resemblance suggests that they have WHAT in common?
They have a common ancestor!

As species continue to evolve, those with some variation now will most likely
1. Have a decrease in variation among individuals
2. Have an increase in variation among individuals
3. There will be no variation
4. The species will become extinct

Describe an adaptation that you remember from class (either from a discussion or video).
How does that adaptation help the species survive?
LOTS OF OPTIONS!

Explain the phrase "survival of the fittest".
Those that are best adapted to their environment will survive and reproduce. The good traits will be passed down to offspring.

Scientists say that whales and bats are closely related. What evidence did they use to support this idea?
They used ANATOMY and bone structure to support this idea. Whales and bats have very similar "arm" structures.

What would be a GOOD variation for a species of bird to have?
1. Different diet options
2. Different colors
3. Both 1 and 2
