evidence

Question 1

What are the five main points used as evidence for proving the occurrence of evolution through natural selection?

Answer 1

#1 Bio Geography
#2 Dating of Fossils
#3 Embryology
#4 comparative Anatomy
#5 Genetic /Molecular biology

Question 2

What is bio geology and how is it used as evidence to prove Darwin’s theory of evolution?

Answer 2

Where when and why animals are. it is used as evidence by comparing close animals in different places and their differences (commonly shown on maps)

Question 3

What is the dating of fossils and how is it used as evidence for Darwin’s theory of evolution?

Answer 3

Using carbon and radioactive dating to find the age of fossils. used by showing changes in species over time

Question 4

What is comparative anatomy and how is it used as evidence for Darwin’s theory of evolution?

Answer 4

Comparing the anatomy of animals to find similarities and differences used by comparing the structures of species to find common ancestors.

Question 5

What did the theory of the tree of life imply?

Answer 5

A common ancestor and that variation was descent with modification.

Question 6

What is carbon dating and how is it used to prove Darwin’s theory of evolution?

Answer 6

dating fossils by comparing the ratios of c12 and c14, has a half life of 5730 years.

Question 7

What is radioactive dating?

Answer 7

Comparing the amount of uranium in rocks to find their age, has a half life of 704 million years.

Question 8

What is a half life and what is it used for?

Answer 8

The amount of time it takes for half a concentration to disappear or change in a substance used in carbon and radioactive dating.

Question 9

What might cause a specie to evolve and adapt a population?

Answer 9

A change in resources land or weather. (anything that might give the species an advantage to adapt to)

Question 10

Why might species who were given the same resource in different places evolve to look and act similar? (armadillo pangolin anteater)

Answer 10

They all gained an advantage from the same traits which caused them to all keep them.

Question 11

Why were similar fossils found on different continents?

Answer 11

We believe the continents were once connected. (Pangea)

Question 12

When compared to a year how long have modern man been on earth if midnight is now?

Answer 12

5 minutes. (till midnight)

Question 13

What is relative dating?

Answer 13

Comparing things around an object to find its date. (or a range for its date)

Question 14

Why do some species have bones, joints, or organs they do not use?

Answer 14

They kept them from an ancestor and never had advantage for losing them.

Question 15

What is a homologous structure?

Answer 15

Similar structures with different functions. (hands)

Question 16

What is an analogous structure?

Answer 16

Different structures with the same functions. (wings)

Question 17

What is a vestigial structure?

Answer 17

Structure that is not used. (whale pelvis)

Question 18

What is molecular biology?

Answer 18

comparing the differences in DNA in attempt to find common ancestors.

Question 19

If two species had less differences in DNA than in their relation with another species what conclusion could you make about those two species?

Answer 19

That they may be more related.

Question 20

What is embryology and how is it used as evidence for Darwin’s theory of evolution?

Answer 20

Examining embryos and how the grow used to show similarities in species and to find common ancestors
