ExplanationGenetic mutations are the primary source of new genetic variation in biological evolution.
#9
What is the term for the process by which unrelated species evolve similar traits in response to similar environmental challenges?

ExplanationParallel evolution is the process by which unrelated species evolve similar traits in response to similar environmental challenges.
#10
In the context of biological evolution, what is genetic drift?
A mechanism of evolution driven by random changes in allele frequencies

#11
What is the concept of 'biological fitness' in the context of evolution?
The ability of an organism to survive and reproduce in its environment
ExplanationBiological fitness refers to the ability of an organism to survive and reproduce in its environment in the context of evolution.
#12
What is the term for a trait that provides a selective advantage and increases an organism's chance of survival and reproduction?
Adaptation
ExplanationAdaptation is a trait that provides a selective advantage and increases an organism's chance of survival and reproduction.
#13
Which of the following best describes convergent evolution?
Similar traits evolving in unrelated species due to similar selective pressures
ExplanationConvergent evolution is when similar traits evolve in unrelated species due to similar selective pressures.
#14
Which concept in evolutionary biology suggests that evolution occurs in short bursts of rapid change separated by long periods of stability?
Punctuated equilibrium
ExplanationPunctuated equilibrium suggests that evolution occurs in short bursts of rapid change separated by long periods of stability.
