Evolution 1
Adaptations help organisms survive by
maximizing their fitness
The ability of an individual to survive and reproduce is known as this.
What is fitness?
The principle that all species can be traced back to a common ancestor is known as this.
What is common descent or ancestor?
False
Preserved remains of ancient organisms used by Darwin to form his theory are known as this.
What are fossils?
The concept of humans selecting desired traits in species for exploitation is known as this.
What is artificial selection?
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
What are members of a population considered to be?
The same species
When features of different species that are similar in function but not necessarily in structure. What is this type of structure called?
Analogous structures
Change in the gene pool due to a random event, not evolution
What is genetic drift?
When considering fossils, organisms that are found buried in the top layer are considered to be the most recent or most primitive?
Most recent
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
Speciation requires isolation.
The type of isolation where organisms are in different locations.
What is Geographic Isolation?
In a forest ecosystem, two species of frogs, Species A and Species B, live in the same environment. They both inhabit the same area, share similar food sources, and have overlapping reproductive seasons. However, these species do not interbreed, even though they are in close proximity. What type of isolation is this?
temporal isolation
Speciation requires isolation.
The type of isolation where organisms use different mating rituals
What is behavioral isolation?
Speciation requires isolation.
The type of isolation where organisms reproduce at different times
What is temporal isolation?
The process in which nature determines which individuals/adaptations are better suited to an environment survive and reproduce
What is natural selection?
The limbs of whales, bats and humans are similar in structure but also have differences in the arrangement of bones in the forelimbs. What would be an explanation for this?
They all have a common ancestor with homologous structures but each one has a different function.
Which one of the following equations represents genotype frequency of a population?
p + q = 1
p2 + 2pq + q2 = 1
p2 + 2pq + q2 = 1
Different variations of the same gene in a population. Offspring can get two different from their parents.
What is an allele?
Structures that have different mature forms but develop from the same embryologic tissues are known as this.
What are homologous structures?
Geologic or behavioral barriers lead to a new species forming over time.
What is speciation?
