100
He is known as the Father of Evolution
Darwin

The ability of an individual to survive and reproduce is known as this.
What is fitness?

Who is known as the Father of Evolution?
Charles Darwin
100
A mistake in the genetic code of a section of DNA is known as a ______________.
mutation
200
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
Homologous Structures
200
Scientist who added to Darwin's theory by clearing up how traits were passed down to offspring through his pea plant experiments.
Mendel
200
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
200
Darwin was from the 1800's. What part of modern science did he lack knowledge of in order to better explain how traits were passed down from parent to offspring?
genetics and DNA
200
This type of symbiotic relationship results when both species benefit
What is mutualism?
300
Preserved remains of ancient organisms
What are fossils?
300
This term refers to different traits and alleles within a population.
What is variation?
300
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
300
This is a type of structure that was once used in a species, but has since evolved to be of no real use.
vestigial structure
300
French naturalist Lamarck is credited with one of the early theories that organisms changed over time from simple to more complex by passing on acquired traits.
Has this theory been proven true or false?
400
common ancestors
400
The concept of humans selecting desired traits in species.
What is Articial Selection?
400
Structures with similar functions but are not similar in origin. These are not proof of a common ancestor but proof that evolution can occur
Analogous Structures
400
This type of isolation is when individuals of a closely related species have different mating seasons/timings
What is temporal isolation?
400
Directional Selection
500
What are the 5 evidences of evolution?
Structures, DNA, Fossils, Embryos, and geography
500
The concept that members of each species are seeking the same food, space, and other necessities is known as this.
What is competition?
500
What is stabilizing selection?
500
This type of isolation occurs when mismatches in mating traits (signals and/or preferences) prevent mating between two species/populations.
What is behavioral isolation?
500
This type of symbiotic relationship results when one species benefits and the other is neither helped not harmed
What is commensalism?
600
What do these homologous structures indicate about these organisms?:max_bytes(150000):strip_icc()/about-homologous-structures-1224763_sketch_FINAL2-4c326d5ec6a5440d9224580a5bbe36d7.png)
They have a common ancestor.
600
When two or more species evolve together, sometimes in response to one another either beneficially or competitively. What is this evolutionary concept called?
What is coevolution?
600
Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?
Natural Selection
600
Genetic drift is a reduction of alleles in a population. This type of genetic drift is when a small group moves away & start a new population
What is Founder's effect?
600
disruptive selection
700
Genetic drift is a reduction in alleles in a population. This type of genetic drift is a chance event that drastically decreases population size
What is bottleneck effect?
700
The bones of this ocean animal have been examined and proven that their ancestors at one time walked on land. They are distantly related to the hippopotamus.
What is a whale?
700
What are 2 of the 5 mechanisms of evolution
Gene flow, non-random mating, mutation, small population size, natural selection/adaptation
700
Convergent evolution describes evolution toward similar traits in unrelated species. What describes the opposite?
What is divergent evolution?
