Question 0

What are the species?

Answer 0

Is a group of organisms so similar to one another that they can reproduce and have offspring

Question 1

Define evolution:

Answer 1

Is the process of biological change in which descendants come to differ from their ancestors

Question 2

What is the theory of evolution that Buffon purposed?

Answer 2

He discussed important ideas of relationships among organisms, sources of biological variation, and the possibility of evolution.

Question 3

What did Erasmus Darwin Purposed?

Answer 3

All living things were descended from a common ancestor. He explained more complex forms of life in less complex forms

Question 4

What did Linnaeus proposed?

Answer 4

He proposed a new system of organization for classifying species.

Question 5

What did Lamarck proposed?

Answer 5

He explained that changes in the environment cause an organism to change it’s behavior

Question 6

What did Lamarck not proposed?

Answer 6

He did not proposed how traits were passed on to offspring and his explanation of how organisms evolve was flamed.

Question 7

Are traces of organisms that lived in the past

Answer 7

Fossils

Question 8

Explain what catastrophism is:

Answer 8

Earthquakes, floods, volcanic eruptions have often happened over Earth’s history. These events have changed and shaped landforms.

Question 9

What is gradualism?

Answer 9

Are low processes that happened in the past. Canyons by rivers cutting trough rock were not result of large scale.

Question 10

What is uniformitarianism?

Answer 10

This theory states that the geologic processes that shape earth are uniform over time.

Question 11

Is the geologic process that is “a key to the past”

Answer 11

Uniformitarianism

Question 12

What is variation?

Answer 12

Is the differences in the physical traits of an individual from those of other individuals

Question 13

What is intraspecific variation?

Answer 13

Is variation among individuals of the same species.

Question 14

Explain what Interspecific variation is

Answer 14

Are differences in variation among species.

Question 15

What is adaptation?

Answer 15

Is a feature that allows an organism to adapt to it’s environment.

Question 16

In what island did Darwin discover the importance of the adaptation in organisms?

Answer 16

In the Galàpagos islands

Question 17

What did Darwin discover, too?

Answer 17

That the Earth is much older than 6000 years

Question 18

Explain what artificial selection is

Answer 18

When humans make use of genetic variation in plants and animals. This is, humans determine which traits are favorable and breed the individuals that have those traits.

Question 19

Heritability is…

Answer 19

The ability to pass traits from one generation to the next.

Question 20

What is natural selection?

Answer 20

Is a mechanism by which individuals have inherited beneficial adaptations and produce more offspring on average to do other individuals

Question 21

What is population?

Answer 21

Is a group of individuals that live in the same area.

Question 22

Explain what overproduction is

Answer 22

Is to have many offspring and some individuals can die

Question 23

Descent with modification is…

Answer 23

Natural selection will result in species with adaptations that are well suited for survival and reproduction.

Question 24

Fitness is…

Answer 24

Is the measure of the ability to survive in a given environment.

Question 25

What is biogeography?

Answer 25

the study of distribution of organisms around the world

Question 26

What is an example of embryology?

Answer 26

The larva of the crabs and the barnacles are identical, but when they grow up they take different forms and anatomy.

Question 27

Explain what a homologous structure is

Answer 27

Is the anatomy that have many organisms (example: humans, bats and moles). They have a similar structure but have different uses. Also, they’re in different organisms.

Question 28

Analogous structures are:

Answer 28

Analogous structures refer to the structures that have a similar use but are present in different organisms

Question 29

Vestigial structures are:

Answer 29

Are structures that were present in the ancestors (for example, the ostrich) but have some modifications
