Genetic Drift
Mechanism of evolution
Natural Selection
Fitness
Theory & the evidence of evolution
100

The term refers to random changes in allele frequencies in a populations gene pool overtime?

Genetic drift

100

This process, first described by Charles Darwin, involves the survival and reproduction of individuals best Suited to their environment

Natural selection 

100

Natural selection slowly causes this overtime 

Evolution

100

Fitness is very important in this type of evolution 

Natural selection 

100

Old bones from long ago animals are called?

Fossils 

200

This type of genetic drift occurs when a small group of individuals establishes a new population with a fraction of the original populations genetic diversity

Founder effect

200

This type of evolution occurs when different species evolve similar traits independently due to similar environmental preserves?

Convergent evolution 

200

Natural selection helps animals to _____ better.

Survive

200

If an animal has a lot of babies it’s fitness is?

High

200

Evolution means that living things change over….

Time 

300

Genetic drift can lead to a outcome, where certain alleles become fixed or lost in a population, reducing genetic variation 

Genetic differentiation 

300

When animals moves & share genes 

gene flow 

300

Traits passed from parents to babies are called?

Inherited traits

300

If an animal has no babies, it’s fitness is?

Low


300

This word mean how new types of plants or animals form 

Speciation 

400

Genetic drift has a more noticeable effect in populations of small size, True or false?

True

400

This random process can change traits in small groups?

Genetic drift 

400

Natural selections help animals…

Survive 

400

Fitness means?

How well an animal can survive & have babies 

400

Mutations help add _____ to a population 

variation 

500

Genetic drift can lead to a loss of genetic variation. true or false?

True 


500

Small change in DNA

Mutation

500

This word means that babies can grow up & have babies of their own

Reproduce 

500

Animals with good traits and many babies have 

High fitness

500

When few animals start a new group this is called…?

Founder effect
