What was Darwin's occupation?

It explains how evolution works.
What does Charles Darwin's theory explain?

An adaptation is an inherited trait that increases and organism's change of surviving and reproducing in its environment.
What is an adaptation?
100
The two types of selection are artificial selection and natural selection.
What are the two types of selection?

m - i - m - i - c - r - y
Spell the word that means "the resemblance of one species go another species".

Plants and animals.
What do naturalists observe?
200
Darwin went to the Galápagos Islands to discover his theory.
Where did Darwin travel to help him discover his theory?

True Mimicry is an adaptation that helps an organism scare away predators.
True or False Mimicry is a type of adaptation.
200
Natural selection is controlled by nature, and artificial selection is forced by breeders. Both selections reproduce, but they are pruduced differently.
What is the difference between the two types of selections?
200
v - a - r - i - a - t - i - o - n
Spell the word that means "a slight difference in an inherited trait of individual members of a species"

A naturalist is a person who studies plants and animals by observing them.
What is a naturalist?

False Darwin was not the first to develope a theory, but his was the best supported.
True or False Darwin was the first to develope a theory of eveloution.

Structural adaptations involve an organism's color, shape, and physical characteristics. Behavioral adaptations involve they way that an organism acts. Functional adaptations involve an organism's internal body system.
Explain the three types of adaptations.

Selective breeding is the breeding of organisms for desired characteristics. It leads to variations because organisms are produced, and they become to look different from their ancestors.
What is selective breeding and how does it lead to variations?

Spell the word that means "an inherited trait that increases and organism's change of surviving and reproducing in its environment".

What era did Darwin develope his theory?

He thought that a storm had carried a small ancestral tortoise population to one of the islands form South America millions of years before.
What did Darwin think about tortoises and their common ansectors?

Camouflage is an adaption that enables a species to blend in with its environment. Mimicry is the resemblance of one species to another species. Both of these things help an organism disguise its self for protection, but they are very different methods.
Explain the difference between camouflage and mimicry.
400
Organisms survive through natural selection and variations because if a variation benefits an organism it is able to live longer and produce more.
How do organisms survive through natural selection and variations?
400
n - a - t - u - r - a - l s - e - l - e - c - t - i - o - n
Spell the word that means "the process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variations".

He took the HMS Beagle to the Galápagos Islands.
What ship did Darwin take to what island?

Mutations can lead to changes in phenotype.
What can mutations lead to?
500
Through natural selection, a helpful generation can be passed down to members of a population. More variations will rise and lead to adaptations.
How do variations lead to adaptations?
500
Natural selection explains how populations change as their environments change.
What does natural selection explain about populations?
