100
Characterized by a molten surface followed by cooling and the formation of oceans, this hell-like eon did not contain life

what is the Hadean eon?

100

This is the species that the father of genetics gregor mendel worked with

What is a pea plant

100

Crossing over occurs during this process which produces 4 gamete cells.

What is meiosis?

100
A new allele is introduced to a population by the movement of an organism to a new population
what is Gene flow
100

Traits can be affected by more than one gene, however, the phenotypes are not continuous

What is Epistasis?

200

This is the current era

What is the cenozoic

200

Armadillo like animal whose fossil was found by Charles Darwin

What is a glyptodon

200

This type of nondisjunction in chromosome 21 causes Down syndrome

What is trisomy

200

Population either goes through a bottle neck event or small set of individuals are transported to a new location with no other individuals of that species

genetic drift

200

Animals of the same species look vastly different and have evolved that way

what is sexual dimorphism

300

This era ends with the KT extinction, famously known for causing all dinosaurs to go extinct

What is the Mesozoic era
300

The first rodent like mammal

what is Morganucodon Watsoni

300

This chain of nucleic acids has catalytic properties

What is RNA

300

Nucleotides in the DNA are changed leading to new traits.

what is mutation

300

This scientist explained how population grows exponentially while food supply grows linearly. 

Who is Thomas Malthus?

400

This is the era in which the first mammals evolved

What is the mesozoic?

400

The early stages of sympatric speciation are being observed in this organism which can be observed on red clover and alfalfa plants

What is a Pea Aphid
400

this is the process in which DNA is converted to RNA and the proteins

What is the central dogma

400
Predators can catch and kill weaker individuals of a species, leading to those with "better traits" to pass them on (generic term)

Natural selection

400

Big freaking sloth

What is megatherium

500
This era ends with the biggest extinction of all time, 96% of all species went extinct at the end of this era

What is the paleozoic

500

This organism was likely the first horse

What is hyracotherium

500

these proteins hold sister chromatids together

what are Cohesin proteins
500

The average of a trait for a species moves up after an event, this type of selection often shifts the average.

directional selection

500

Females of a species select a less fit male since in the past the trait they perceived to be attractive did not reduce their fitness. 

What is Runaway selection
