Comparing the fossil dragonfly to the modern one, what assumptions can be made about the dragonfly?
They used to be much larger and have evolved to become smaller.

Animals living in extremely cold environments usually have special characteristics like thick blubber, thick fur, or other methods of conserving heat. What do these characteristics represent?
Adaptations because they have gained those traits due to their environment

Even though the finch and sparrow are two different types of birds, they have similar beaks. Which statement best explains why their beaks are similar?
They eat the same type of food
200
All humans have different fingerprints even though they are the same species. What type of influence causes this diversity among the same species?
Genetic Variation

Predict what will likely happen to the number of species that go extinct if the trend of human population growth continues and reaches 8 billion by the year 2030.
The number of extinctions will reach up to 60,000

A scientist believes that American dogs evolved from Canadian wolves. To test this hypothesis, the scientist should —
* Study the fossil record to prove that they have HOMOLOGOUS structures

In a population of mice that live in the desert, some are light brown and others are dark brown. Predators can more easily see the dark brown mice. Over time, which is likely to happen to the ratio of mice?
There will be more light brown mice than dark brown mice.

What most likely caused the finches on the Galapagos Islands to have beaks that were different from the finches living on the South American mainland?
The types of food they were eating because if they did not have the proper beak shape they would die.

Natural selection does not give organisms new traits when they need them. Instead, it acts on __________ that already exist in a population.
Variation

When looking at two tree frogs of the same species, Thomas noticed one of the frogs was a little darker in color than the other frog. Olivia also noticed that one of the frogs had longer toes than the other frog. These slight differences observed within members of the same species are called —
Variation

When organisms must fight for limited resources like food, water, or space, this interaction occurs.

Explain why this is NOT an example of natural selection that could have occurred in the aftermath of the Permian-Triassic Extinction event?
-The immediate emergence of new amphibian species.
It does not describe how the animal survived based on the environmental conditions

Sometimes bones in the front limbs of animals are very similar in structure. What do we call similar bone structures that indicate a link to a common ancestor?
Homologous Structure
500
The term used to describe how animals become different species through means of separation (like a river or mountain).
Geological Isolation
