Evidence for evolution
Tracing these "things" by digging them up from sedimentary rock can show us how organisms evolved over time.
What are fossils
This "thing" comprises of all the possible genes/genotypes of a population
What is gene pool
A barrier is made between two populations, reproductively isolating them
What is geographic isolation
Finches with various beak sizes. Certain finches that happen to have a good beak for a certain seed will evolve to eat that seed and pass on its genes.
What is Darwin
The country that Mr. Shin was born in
What is Korea
Kangaroos, for some interesting reason, are only found in Australia. Hmm...
What is geographic distribution
Legs that are too long make ostrich wobbly. Legs that are too short make ostrich run slower. Legs that are medium/average length are just right.
What is stabilizing selection
Different mating seasons cause reproductive isolation
Giraffes decide to grow long necks and pass on their genes for long necks to their offspring, increasing their fitness.
What is Lamarck
The college that Mr. Shin goes to
What is Brandeis University
There are few differences in the amino acid order for a certain protein between humans and primates
What is genetic code (DNA)
It helps to have either very small fins or very big fins.
What is disruptive selection
Red seaweed only grows in the bottom of Finn Lake inside the narrow holes of coral. Blue seaweed only grows in the open near the shore of Finn Lake. One group of turtles have very very narrow, pointy mouths. Another group have wide, big mouths. The two groups become reproductively isolated.
What is ecological isolation
A group of birds arrive in Texas. They realize that they shedding their feathers (due to the hot weather) will make them cool down and adapt better. The birds pass on their genes to shed feathers.
What is Lamarck
(Lamarck = acquired. Darwin = inherited).
Ms. Sarah Shin
(this person is sort of important to Mr. Shin
Who is Mr. Shin's sister
Tail bones
What is vestigial structure
The longer the antlers for stags (male deer), the better.
Some female blue penguins hunt for tuna fish in a particular fishing location to attract a mate. Other female blue penguins hunt for tuna fish in another fishing location to attract a mate. Red and purple penguins, living in the same area, do not like tuna fish.
Behavioral isolation
Geckos exhibit variation in the length of their tails. One day it is suddenly advantageous to have short tails and have shorter tails increase fitness. Geckos with shorter tails become lucky and pass on their genes.
What is Darwin
Walnuts
What is Mr. Shin allergic to
Same structure, different function
What is homologous structure
Gene frequency stays exactly the same over the years.
What is genetic equilibrium
A liger or mule that cannot reproduce.
What is genetic incompatibilities
Certain squid can camouflage with their environment and hide from predators. Some squids happen to be "better" and "faster" at camouflaging than other squids. The squids decide when to camouflage and their decision to camouflage increases their fitness. The squids that can camouflage more quickly pass on their genes
What is Darwin
