Theory Of Evolution By Natural Selection

Question 1

Evolution

Answer 1

Change to species over time

Question 2

Micro evolution

Answer 2

Change to trait frequency

Question 3

Macro evolution

Answer 3

Larger changes to organisms(speciation)

Question 4

Overproduction

Answer 4

The number of offspring produced by a species is greater than the number that can survive , reproduce and live

Question 5

Struggle for existence

Answer 5

Organisms compete for limited recourses such as food, water, and a place to live

Question 6

Variation

Answer 6

Differences in traits among species are passed on to the next generation

Question 7

Survival of the fittest

Answer 7

Species that have traits that give them an advantage are better to compete and survive

Question 8

Origin of new species

Answer 8

By the inheritance of successful variations: new species arise by the accumulation of inherited variations

Question 9

Evidence of evolution

Answer 9

Fossil records
Transitional fossils
Homologous structures
Analogous structures
Biogeography
Molecular biology

Question 10

Molecular biology

Answer 10

If two species have similar patterns in their DNA, it is indicated that these portions of their DNA were most likely inherited from a common ancestor
