Evolution 3
Evolution 4
100
A change in an organisms DNA sequence
What is a mutation
100
He is known as the Father of Evolution
Who is Charles Darwin?
100
He believed that acquired traits could be passed to offspring
Lamarck
100
The process in which a species has changed over time is known as this.
What is evolution?
200
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
What are Homologous Structures?
200
The evolution of new species even though the population stay within the same geographic regions
what is sympatric speciation
200
In Hardy Weinberg equilibrium, q2 represents:
what is the frequency of the homozygous recessive genotype
200
Farmers breed chickens that lay larger eggs
What is Artificial Selection
300
Preserved remains of ancient organisms
What are fossils?
300
A trait that improves an organisms ability to survive and reproduce in it's environment
Adaptation
300
When males appear fancy and females appear drab even though they are members of the same species.
What is sexual dimorphism
300
Both bats and whales have evolved to perform Echolocation independently of one another
what is convergent evolution?
400
Embryology
400
The process by which female long-tailed widow birds only breed with males who have the longest tails
Sexual Selection
400
The middle variation of a trait is selected
What is stabilizing selection?
400
The smallest unit that can evolve
What is a population
500
The process by which individuals that are better suited to the environment survive and reproduce passing their genes to the next generation.
What is Natural Selection?
500
Organs/ structures that no longer serve a purpose and have disappeared or reduced in size
Vestigial Organs/Structures
500
This type of vestigial structure is found in our digestive system. This organ used to be used to digest cellulose for our ancient ancestors.
What is the appendix?
500
Medium-sized seeds are a favourite snack of finches. Suppose all the medium-sized seeds get eaten, leaving behind only small and large seeds
what is disruptive selection?
600
Human hemoglobin differs from Chicken hemoglobin by 27 amino acids
Biochemical/molecular evidence of evolution
600
Natural selection favours an extreme phenotype
what is directional selection
600
A shift in allele frequencies over multiple generations
What is microevolution
600
Moth species mate at different times of the day preventing breeding between different species
Prezygotic barrier - temporal
700
A mountain range separates a population of anole lizards leading to speciation
Allopatric speciation
700
Bird wings and insect wings perform the same function, but have different anatomy making them this type of structure
What are Analogous Structures?
700
Dark colour allele in moths is dominant and has a frequency of 0.7. What is the frequency of the heterozygous phenotype?
What is 0.42
700
When a few individuals start a new population. Allele frequencies differ from the original population.
What is the Founder Effect?
