Natural Selection
For natural selection, organisms that are best adapted to an environment will (1) _________________ and (2) _________________ more than others.
(1) Survive (2) Reproduce
True or false? The theory of evolution predicts that closely related species will NOT show any similarities in DNA sequences.
False
Which layer is the oldest AND the youngest?
Youngest: Layer M
What symbols do you use to represent traits or characteristics that are present and absent?
+ for Present
- for absent
Name one infinity stone from the Marvel Universe
Time, soul, power, mind, space, reality
Look at the photo and identify which condition of Natural Selection does it represent AND why.
True or false: All the structures that embryos have in common (gills, tails, limb buds) will continue to exist when the embryos develop into full grown organisms.
False!
The law states the oldest layers are on the bottom and the youngest layers are on the top.
What are cladograms used for?
They are used to represent the possible relationships between different organisms based on the presence or absence of certain characteristics.
Which TV does this theme song belong to?
Game of Thrones or House of Dragon
What is it called when an organism or species changes to become better suited to their environment and survive?
Adaptation
If there is 95% similarity between two organisms, what does that tell you about the number of differences when comparing their DNA?
That there are few differences between the DNA sequences since they have a high percentage of similarity.
Give an example of a vestigial structure
Pelvic bone in whale, leg buds in snakes, appendix in humans, tail bone in humans
Looking at the cladogram, (1) What trait does the gorilla and the human have in common? (2) Between the gorilla and human, what trait does the human only have?
(1) No tail (2) Bipedal
What color pants does Jake from State Farm wear (this was a commercial)?
Full points - Khakis

Peacocks with the largest and brightest feathers will always have better chance at finding mates to reproduce than the peacocks with the shorter and more dull feathers. Explain what would happen to their populations overtime?
The peacocks with the large and bright feathers will increase in population because they will be able to survive and reproduce. The shorter and more dull feathers would decrease in population.
Even if your DNA and a Rhino's DNA is 88% similar, why are you not directly related?
It's because all organisms share the same genetic information. This includes DNA sequences, amino acids, and proteins.
What vocabulary words best fit the descriptions below?
(1) Structures that do the same job or function but the organisms are not related by a common ancestor.
(2) Similar structures in different organisms that have different jobs or functions.
(1) Analogous Structures
(2) Homologous Structures
In your own words, explain why the salamander is more closely related to the lizard than to the shark.
The salamander is more closely related to the lizard because it has more traits in common - jaws and lungs! But the salamander and shark only have jaws in common.
ZERO! Because they have cartilage.
