Evolution and Natural Selection
Who created the Theory of Evolution?
Who is Charles Darwin.
What is Speciation?
What is the formation of new species when populations of a species become isolated and evolve differently.
What is a Boundary?
What is a line that marks the limits of an area or a limit of a subject or sphere of activity.
What is extinction?
What is the termination of a species by the death of its last member or female.
What are some evidence of evolution?
What is fossil records, discovery of the structure of DNA and mechanisms of mutations.
(Any of these answers are correct)
What is Allopatric speciation?
What is Speciation by geographic isolation.
What is a Convergent boundary?
What is when two or more lithospheric plates come together.
What are the causes of Mass Extinction?
What is tectonic movements, super-volcanic eruption, climatic changes (droughts and ice ages), and meteor impact.
What is the process of natural selection?
What is the process by which change and adaptation is seen through populations of living organisms.
What is Sympatric speciation?
What is Sympatric speciation occurs when there are no physical barriers preventing any members of a species from mating with another, and all members are in close proximity to one another.
(Any Variation of this is correct)
What is a Divergent boundary?
What is when two tectonic plates move away from each other.
Roughly about how many species go extinct every year?
What is between 10-100 species per year.
How does natural selection contributes to biodiversity?
What is genetic diversity, natural variation, reproduce more successfully, offspring of fitter individuals may inherit the genes that give the advantage.
(Any of these answers are correct)
What is Parapatric speciation?
What is when a species is spread out over a large geographic area, but only reproduces with local species, resulting in the development of a new species.
(Any variation is correct)
What are types of Convergent boundaries?
What is oceanic boundaries, Oceanic-continental boundaries and Continental-continental boundaries.
How is extension estimated? What records are used?
What is estimated from the fossil record.
What steps are involved in Natural selection? Name all 5.
What is:
Variation
Inheritance
Selection
Time
Adaptation
What are physical barriers causing speciation?
What are land bridges and congenital drift
What is a Transform fault/boundary and name an example.
What is when two tectonic plates slide past one another.
Example:
the San Andreas fault line, California
What was the first Mass Extinction?
What was during the Ordovician-Silurian, 440 million years ago.
