A biological ____________ is a group of interbreeding populations that is reproductively isolated from other groups

• species

• phylogeny

• family

• hybrid

An inherited trait which increases the chance of survival/reproduction in a population is ...

• gradualism

• natural selection

• mutation

• adaptation

Darwin and Lamarck agreed that changes in a population are linked to ...

• genetics

• environmental conditions

• use or disuse of physical features

• acquired characteristics

Natural selection causes the frequency of advantageous alleles to ...

• increase in a population over time

• decrease in a population over time

• remain constant in a population over time

• show large variation in a population

What is the definition of "gradualism"?

• individuals gradually becoming more adapted to their environment over their lifetime

• slow and steady change of a species over time

• variation in traits among members of the same species

• rapid change of a species over time

Many organisms possess parts that were used by a common ancestor but are no longer useful or helpful. An example is the leg bone found in the whale skeleton. What evolution term is being described?

• homologous structures

• vestigial trait

• divergence

• punctuated equilibrium

In Darwin's theory of evolution, do individual organisms or populations of organisms evolve?

• Individuals evolve in their own lifetimes

• populations evolve over a period of time

Which question below would LAMARCK ask based on his theories?

• How would shorter necked giraffes survive to reproduce and pass on the "need" for longer necks?

• Why can't shorter necked giraffes feed on lower vegetation and grasses?

• Would taller necked giraffes help out shorter necked giraffes to survive?

• Will smaller giraffes be better adapted to hide from predators than longer necked giraffes?

Which theory did LAMARCK propose about evolution?

• Use and Disuse/Theory of Acquired Characteristics

• Theory of Natural Selection

• Theory of Evolution

• Theory of Antibiotic Resistance
