This is the process by which species change over time.
evolution
This term describes the process by which organisms better adapted to their environment tend to survive and produce more offspring.
Natural selection
A river separates a population of foxes. Over time, these two populations evolve separately. What type of isolation is being described?
Geographic
This term describes a population that if not evolving

Lamarck, a scientist that influenced Darwin, was known for his (incorrect) theory of evolution. What did his theory propose?
Individuals could pass on traits that they inherited in their lifetime.
This is the idea that only the strongest and best-suited animals will survive and reproduce.
survival of the fittest
This term refers to structures that have lost most or all of their original function, such as the human appendix.
Vestigal
The change in allele frequencies is also known as
evolution
RNA stands for this
ribonucleic acid
Darwin observed that species varied over time, globally, and...
locally
This is the term for traits that enhance an organism's chance of survival and reproduction in a specific environment.
Adaptations
These structures, such as the human arm and the whale flipper, indicate a common ancestry despite different functions.
Homologous structures
A random chance event that causes a dramatic change in a population's alleles
gene flow
Wireless Fidelity
Darwin noticed that species changed over time, what kind of variation is this?
time
This type of selection involves the selection of traits based on desirability. This selection is NOT by nature, but more by choice.
artificial
This term refers to the genetic divergence of populations leading to the formation of distinct species.
Speciation
One condition needed for a population to be in Hardy-Weinberg Equilibrium
No mutations, no gene flow, random mating, large population, no natural selection

Nitrogen
Darwin noticed that Rheas (flightless birds) varied in size and characteristics across South America, even though they were the same species. Which kind of variation is this describing?
Local
In a forest with dark soil and plenty of green foliage, a population of beetles exhibits a range of colors, from dark brown to bright green. As a new predator, a species of bird, moves into the area, it begins to prey on these beetles. The bird has excellent vision for spotting colors that stand out against the background. Which beetle color would be the best at surviving in this scenario?
Green
Two species of foxes mate in different seasons. What type of isolation is this?
Temporal
Why do mutations disrupt genetic equilibrium
They create changes in DNA, which can be passed down to offspring, affecting allele frequencies
