Put These Events in Order:
Multicellular Life Evolved, Prokaryotes Evolved, Photosynthesis Evolved, Eukaryotes Evolved, Oxygen Built up in the Atmosphere
What are: Prokaryotes Evolved, Photosynthesis Evolved, Oxygen Built up in the Atmosphere, Eukaryotes Evolved, Multicellular life Evolved?

Describe Natural Selection
What is the process of populations changing as individuals fail to survive challenges?
100
For a population of Mountain goats, with allele frequencies of B= 0.25 & b= 0.75 for genes coding for horn curliness, this would be the expect number of Heterozygotes if the population is in HW Equilibrium.
Equation:
A + a = 1
A*A+ 2* A*a + a*a = 1
What is 0.375?
2 * 0.25 * 0.75
100
This is direct evidence of evolution.
What is something people have observed & recorded?
100
Closely related species are this on a cladogram.
What is closer together?
200
This is how much of a radioactive substance remains after a half-life has passed.
What is 50%?
200
Birds can either have dark colored feathers or light feathers. Dark feathers would be this if the bird needs to hide as part of its day to day existance.
What is an adaptation?
200
The Allele Frequency of a = 0.3 means this is the Frequency of A.
What is A = 0.7?
200
This structure indicates that two species are related because it serves no apparent purpose in one of them.
What is a vestigial structure?
300
This is our primary evidence that species can go extinct.
What are fossils?
300
If an allele not under selective forces changes in frequency from generation to generation it is likely due to this force.
What is Genetic Drift? (Best Answer)
Alternative answer: What is Gene Flow? (Runner Up)
300
Selecting against the average trait in a population would be this type of selection.
What is Disruptive Selection?
300
Structures which are from two unrelated organisms living in a similar environment are called this.
Ex: Hippos & Seals both have large amounts of fat in their bodies.
Analogous Structures

For the Known Phylogeny, between Rugby & American Football (the NFL) this is the sport more closely related to Traditional Soccer.
What is American Football?
400
The horse is an example of this type of evolution.
What is Gradualism?
400
Natural Selection requires this to be present in a population
What is Variation?
400
Lamarkian Evolution states that organisms struggling to overcome challenges exaggerates existing traits. Darwinian evolution explains this process this way.
What is animals with more advantageous traits survive leading to more individuals with those traits?
400
If we separate two populations from each other & it creates two new species this is an example of this type of speciation.
Allopatric Speciation
400
The shape of this phylogenetic tree from the original image indicates this kind of evolution.
What is Adaptive Radiation?
500
A substance has as 12.25% of a radioactive substance remaining, it is this old if the half life of that substance is 10 years.
What is between 30 & 40 years?
500
This causes Sympatric Speciation
What is Sexual Selection?

If this diagram is a cladogram showing the evolution of entertainment for the following "Groups": Soap Operas, Radio Stations, Podcasts, Real Housewives & Property Development Shows, these colored boxes (clades) would include Soap Operas.
What are the Green & Blue clades?
