The process of how organisms acquire adaptations over time is called this.
What is evolution
100
This is an inherited trait that helps an organism survive.
What is an adaptation?

The driving force in evolution is.....
What is Natural selection?

Which species (H, I, or K) is the closest relative to Species J?
What is Species K

All living things have this in their cells, suggesting a common ancestor.
What is DNA?

As a populations’ habitat changes over time, a species with a high level of genetic variation would have this.
What is a better chance of survival?

Darwin concluded that finches with ____________ beaks are best adapted to eat seeds from very large shells. A. small B. sharp pointy C. large D. small skinny
What is large?

The body structures for a population of chimpanzees were stable for a long time. Then, their body structures changed, making the chimpanzees stronger. Why did this happen?
What is change in their environment

Models that look like tree branches that show evolutionary history and that all living things have a common ancestor.
What are cladograms?

Mata Mata turtles have adapted to their habitat to protect themselves from predators. Which BEST describes this adaptation? A. mimicry B. Camoflage C. parasitism D. mutualism
What is camoflage?

The climate of a certain area is cold, and snow is found on the ground most of the year. Equal numbers of two populations of rabbits are introduced into this climate by a group of scientists. One of the populations is brown and the other is white. Over several generations, this will happen.
There will be more white rabbits than brown rabbits

Two students were challenged with taking imaginary species and placing them on an evolutionary tree. Their models are shown below. Inspect the models and then answer the questions.
Which model do you think is correct?
What is the model on the left

Which is most likely to be related to a human based upon similar anatomical structures? A. flea B. fish C. coyote D. grasshopper
What is C, the coyote?

What best explains why the wing of a bat and a fin of a whale are similar? A. a mutation caused them to be similar B. they both share a common ancestor C. a simple coincidence between the two
What is they both share a common ancestor?

"Survival of the fittest".
What is the advantage/ability for an individual in a population to survive, and reproduce.
400
The process by which one population evolves into two or more different species
What is Speciation
500
Over 99% of the DNA in chimpanzees and humans are identical, suggesting this.
What is that the two species share a common ancestor?
500
Explain how the separation of the continents through plate tectonics result in new species.
What is once a population becomes separated they can no longer breed, so over time, the separated populations evolve differently and eventually become different species?

Explain how Darwin’s observations of finches in the Galapagos Islands led to his ideas about natural selection.
-Finches on the islands were slightly different from those found on the mainland.
--Slight differences in finches from island to island.
-Beak shape.
--Based on the type of food eaten; finches were adapted for the type of food they ate.
-Darwin hypothesized that an ancestral species of finch from the mainland ended up on the Galapagos, and the finches were scattered to different environments.
--Then, had to adapt to different conditions, and over many generations evolved into new species.

Why are advantageous traits more likely to be passed onto offspring?
What is they are more likely to survive and reproduce
