Honors Biology Evolution Questions
and Answers Graded A+
What is natural selection?
✔✔ Natural selection is the process where organisms with traits best suited to their environment
are more likely to survive and reproduce.
How do mutations contribute to evolution?
✔✔ Mutations introduce new genetic variations, which can lead to new traits that may be
advantageous in a changing environment.
What is the significance of fossil records in understanding evolution?
✔✔ Fossil records provide evidence of past life forms and show how species have changed over
time.
What is genetic drift?
✔✔ Genetic drift is a random change in allele frequencies within a population, which can lead to
evolutionary changes over time.

, How does gene flow affect evolution?
✔✔ Gene flow introduces new alleles into a population, increasing genetic diversity and
potentially altering the course of evolution.
What is the concept of common ancestry?
✔✔ Common ancestry suggests that all living organisms share a common ancestor from which
they have evolved over time.
How does geographic isolation lead to speciation?
✔✔ Geographic isolation prevents populations from interbreeding, leading to the development of
new species as they adapt to different environments.
What is adaptive radiation?
✔✔ Adaptive radiation is when a single species evolves into multiple distinct species, each
adapted to a different environment.
What is the importance of homologous structures in evolutionary biology?
✔✔ Homologous structures show how different species share common anatomical traits due to a
shared evolutionary ancestor.
