Differences between species

What is Variation?

This means a slow steady change

What is Gradualism?

These are all examples of this

What are vestigial structures?

Happens when an event in nature causes the

most extreme variation of a species to survive

What is Disruptive Selection

This is an example of this

What is Coevolution

Charles Darwin came up with his theory of evolution with this

What is Natural Selection

h

The ideal that each offspring is different

from each other

What is the ideal that There is

variation within populations

This picture represents this ideal of natural selection

h

What is the ideal that Individuals that survive and reproduce are those

with favorable variations -or- Some variations are

favorable

This video shows this specific ideal of Natural Selection

What is the ideal that not all offspring will

survive?

This image of one ostrich running faster than another ostrich represents this ideal of natural selection

What is the ideal that Individuals that survive and

reproduce are those with favorable variations -or- Some

variations are favorable

Came up with the ideal of Uniformitarianism

Who is Charles Lyell

Came up with the ideal that body structures that are in use will develop

while structures that are not in use will not

Who is Lamarck?

Came up with the ideal that we see when we look at this:

Who are animal breeders

Darwin used his ideal that only those individuals that are able to gain the most

resources will survive

Who is Thomas Malthus

His hypothesis using the giraffes helped Darwin understand that a structure can be

modified to increase fitness in an environment

Who is Lamarck

The type of curves that are used in distribution curves

What are bell curves

This type of curve happens when the environment selects a species

that is average in its variation

What is Stabilizing selection

The peppered moth / human involvement in nature showed us

this selection example

What is the directional selection

This type of selection can occur when a population gets separated

into two different population

What is Disruptive selection

This selection can cause a speciation to occur

Disruptive Selection

This type of evolution happens where similar adaptations occurs even though they have different ancestors

What is Convergent Evolution

The variations between these foxes are caused by these mechanisms

What are: 1. Sexual reproduction

2. Law of independent assortment3. Crossing over

4. Mutations

This image of the evolution of a horse’s leg took a very long time.

This is an example of this:

Gradualism

A small mistake in the genetic code that can create a change in the

phenotype

What is a mutation

This type of evolution happens rapidly after a genetically

stable period

Punctuated Equilibrium
