All evidences of evolution are trying to prove that different organisms have a _________________ ________________. (2 words!)
COMMON ANCESTOR (KEY KEY KEY)

The type of selection in which the average (or mean) is the advantage is called ____________ selection.
Stabilizing

What is speciation?
The creation of a new species

Who had similar findings to Darwin, who wrote an essay to Darwin that prompted Darwin to publish his famous book?
Alfred Russel Wallace

In butterflies, some have black wings and some have white wings. Which part of the Theory of Natural Evolution does this show?
Natural Genetic Variation in a population
200
The picture above is an example of which type of evidence?
Homologous structures
200
The type of selection where BOTH of the extremes are favored is called ______________ selection.
Disruptive selection
200
What are the three ways a new species can be developed?
Geographical Isolation, Reproductive Isolation, Temporal Isolation
300
What feature of what organism did Darwin observe to form his Theory of Evolution?
Beaks of Finches

Organisms which are adapted to their environment will ______________________________________.
Survive and pass those adaptations on to their offspring
300
Which organism is most closely related to the horse?
Zebra
300
The type of selection where ONE of the extremes is favored is called _____________ selection.
Directional

A population of deer lived in plain. One day, after an earthquake, there is a large valley in the middle of the plain with two separate deer populations on each side.
This will lead to what type of isolation?
Geographical
400
Who proposed the Theory of Use/Disuse?
Jean Baptiste de Lamarck

In a species of worms, some worms are nocturnal (awake at night) and some worms are diurnal (awake during the day). The predator of the worms are awake during the day.
What is the adaptation?
Being nocturnal
400
The image above is comparing what?
Embryos (early stages of development) between organisms
400
In lizards, most lizards have a medium tail. One year, predators start mistaking the longer tails for snakes and refuse to eat the lizards with the longer tails. What type of selection will this show?
Directional (the long-tail extreme will be favorable)
400
One species of lizard mates in the fall while the other species mates in the spring.
This is an example of what type of isolation?
Temporal Isolation
500
Student 1 believes that giraffes stretched their necks bit by bit until they were able to reach the leaves at the tops of trees. They then passed on the gene for the long necks to their offspring.
Student 2 believes that giraffes are born - some with long necks and some with short necks. The ones with long necks can reach the tops of trees and therefore will survive and reproduce. The short neck giraffes will not get food and die before reproducing.
Which student thinks like Lamarck? Which student thinks like Darwin?
Student 1 - Lamarck
Student 2 - Darwin

In a species of worms, some worms are nocturnal (awake at night) and some worms are diurnal (awake during the day). The predator of the worms are awake during the day.
What will happen to the worm population over time?
Number of nocturnal worms will increase, number of diurnal worms will decrease
500
What are the seven pieces of evidences for Evolution?
Adaptations, fossil record, embryology, homologous structure, analogous structures, vestigial structures, biochemistry

In a population of rabbits, there are rabbits with brown fur, white fur, and spotted (Brown AND White) fur. The spotted rabbits are the moderate trait.
Their environment changes and now there are only brown rocks and white rocks present.
What type of selection is present?
Disruptive Selection
500
A population of insects mated over the period of hundreds of years. Eventually, due to mutations and preferences, all of the insects could no longer mate with each other.
This is an example of what type of isolation?
Reproductive Isolation
