Homologies in bone structure, but difference in function like those illustrated in the image, demonstrates evidence that
these organisms are not well adapted
these organism share common ancestry
these organisms all share the same DNA sequences
these organisms are members of the same species
What conclusions can be made based on this table shown?

The giant panda and the red panda are most closely related
The giant panda and the racoon are most closely related
The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide biogeographical evidence that -
They live in the same type of environment.
have slowly evolved to become herbivores.
exchanged DNA in the past.
have a common ancestor.
In a population of birds, intermediate beak size is selected against, and both very small and very large beak sizes are favored. What type of selection is this an example of?
directional
disruptive
normal
stabilizing
Natural selection results in change overtime by acting on traits that are
heritable.
new.
mutated

Genetic Drift
Natural Selection
Gene Flow
Gene Expression
A change in the frequency of a gene variant (allele) in a population due to a random event.
Genetic Drift
Gene Frequency
Natural Selection
Evolution
Darwin observed many finch species on the Galapagos Islands. To explain these observations, he proposed that each species evolved from the same common ancestor, which was a finch species that migrated to the islands from the mainland. What additional evidence did Darwin use to support his explanation?
The finch populations were very numerous, and different species often bred with one another.
The finch species lived in different habitats on different islands, which isolated them from one another.
The finch species were distributed evenly among all of the islands, but did not interbreed.
The beaks of the finches were identical, allowing them to eat the same foods on any of the islands.
How often a specific gene shows up in a population’s gene pool?
Mutation
Recombination
Genetic Drift
Gene Frequency
