What is Natural Selection?
The environment exerts pressure on a population to change and nature selected those with the best traits to survive.

Give an example of homologous structures.
human arms, bat wings, and dolphin flippers (same bones, different shapes and sizes for different functions)

What are vestigial structures? Give an example.
structures that we have, but no longer use/need. (whale hip/leg bones)

All living things are classified using taxonomy. The system used to name the species is Binomial Nomenclature in which they use what taxa to name name them? ( there's 2)
What is Genus name and species name

New Blue Jays move into the population who have a different hue of blue than the Blue Jays. What mechanism of evolution is this?
Gene flow
200
The largest taxonomic level representing the most diversity is the ________________.
Domain

Two organisms, such as bats and insects are not related, but they both have wings because they live in similar environments. What are these structures called?
Analogous Structures

According to the diagram, which are the oldest fossils?
Trilobites

The order of taxonomy from broadest to most specific is..
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

In a species of frogs, there is a new color that pops up into the population that benefits the frogs with that new color. What mechanism of evolution is this?
mutation

Describe what "fitness" means in regards to natural selection.
the organisms ability to survive and reproduce

The diagrams below show the skeletons of two different animal species. How does comparing the skeletons of these animals provide support for the scientific theory of evolution?
A. It provides information about the organisms' habitats.
B. It shows possible common ancestry between organisms.
C. It provides information to determine the organisms' ages.
D. It shows possible chromosomal similarities between organisms.

The North American cactus and African Euphorbia (plant) are species that have evolved similar structural adaptations to conserve water and survive in a hot, dry, desert environment. They appear similar in appearance, but are not related. What type of evolution are these species demonstrating?
A. Coevolution
B. Divergent
C. Convergent
D. Mutualism
C.

The hypothesis that evolution of a species occurs gradually over time as a slow and constant process is known as
Gradualism
400
the ability of an organism to survive and reproduce fertile offspring
fitness

Over evolutionary time, many cave-dwelling organisms have lost their eyes and whales have lost their hind limbs. How can natural selection account for these losses?
A. Natural selection accounts for these losses because if you don’t use it, you lose it.
B. The ancestors of these organisms experience harmful mutations that forced them to new habitats that these species had not previously used.
C. Under particular circumstances that persisted for long periods of time, each of these structures did not benefit the organism in their environment.
D. These organisms did not have the proper nutrition leading to disease.
C.

What does this picture tell us about these organisms? Why?
They share a common ancestor because their development is similar.
