Honors Biology – Evolution Questions and Answers Graded A+ What is the significance of genetic drift in small populations? Genetic drift causes random changes in allele frequencies, which can significantly impact small populations. How does the concept of speciation relate to evolution?

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 pro...
