Bozeman Bio Natural Selection

Who is Charles Darwin famous for?

• Inventing evolution

• Giving us a mechanism that explains how evolution occurs

• Discovering the gene pool

• Creating the first biology textbook

What is biological evolution defined as in this class?

• Adaptation of organisms over time

• The process of natural selection

• Changes to the gene pool

• The study of animals

What can cause evolution according to the video?

• Stable population sizes

• No mutations

• Random mating

• Migration

What is the smallest unit that can evolve?

• An organism

• A population

• An allele

• A gene

What leads to adaptations in a population?

• Large population sizes

• Equilibrium in the gene pool

• Natural selection

• Random mating

How do bacteria develop resistance to antibiotics?

• Through binary fission

• Through mutation

• By taking antibiotics

• By increasing their population size

What is the phenotype of the light peppered moth?

• Homozygous dominant

• Homozygous recessive

• Heterozygous recessive

• Heterozygous dominant

What happened to the peppered moth population during the Industrial Revolution?

• The dark moths became more common

• No significant change occurred

• The population size decreased

• The light moths became more common

What does natural selection lead to?

• Equilibrium in the gene pool

• Adaptations

• Stable population sizes

• No change in allele frequencies

Why is natural selection important?

• It ensures all organisms survive

• It prevents mutations

• It maintains the gene pool

• It's the only mechanism that leads to adaptation
