Evidence of Evolution
The function of body hair through generations.
Warmth.
What was the largest extinction on Earth?
Permian-Triassic Extinction.
What is the Founder Effect?
When a tiny subset of a large population is used to start a new colony, there is a loss in genetic variation.
If two cats are different breeds, are they still the same species?
Yes.
What qualities can help a prey to survive a predator?
It all depends on the environment they come from, not the qualities.
A big difference between the Cave Fish and Modern Fish.
The Modern fish has eyes.
What's known as the 6th extinction?
The Anthropocene extinction
What's the bottleneck effect?
An extreme case of genetic drift occurs when a population's size is drastically decreased.
Name the three types of isolation.
Behavioral, Temporal, and Habitat isolation.
Changes that the predators and prey will be facing with time.
The population will increase, as well as the preying.
What's a Homologous Structure?
Similar structures that evolved from a common ancestor.
What was Earth's surface like during the Ordovician?
Landmasses were all together.
What's believed to be the outcome of the "Long Walk"?
The increase of xeroderma pigmentosum (XP) cases.
What's habitat isolation?
When habitats prefer a lower possibility for mating.
If there were any non-visual predators in the area, would a specific prey have an advantage?
How the prey smells. If all the preys smell the same then, there would be no advantage.
Is Eyes on Cave Fish an example of Analogous structures?
No.
Evidence that the Permian happened.
The eruptions of volcanoes were the cause of global warming and the lack of oxygen in the oceans.
What's xeroderma pigmentosum?
A skin condition that causes the skin to have extreme sun sensitivity, increasing the risk of skin cancer.
What's the difference between temporal and behavioral isolation?
Temporal isolation is temporal breeding isolation, and behavioral prevent the interbreeding between two populations.
Is time a disadvantage for future generations?
No, because the more time passes, the more the generations start growing.
What's the difference between Embryology and Comparative Anatomy?
Embryology is how similar closely related organisms look before they're born, comparative anatomy is to compare different anatomy.
Name of the peninsula that helped as evidence of the end of the Cretaceous.
Yucatán Peninsula of Mexico.
Frequency of people from Navajo with xeroderma pigmentosum.
1 in 30,000.
What's the difference between prezygotic and postzygotic barriers?
prezygotic is anything that prevents mating and postzygotic blocks reproduction after fertilization.
Is there a disadvantage to being prey?
The population still increases over time, although they're being preyed on.
