What is James Hutton's uniformitarianism?
Definition

A slow steady uniform change that could explain why the Earth looks the way it does.

Term
What does the theory of inherentence of aquired characteristics state?

Came up with Theory of Catastrophism. 

Term
What is the theory of Catastrophism?
Definition
The world was shaped by natural disaters, found examples in flooding.
Term

The Theory of Uniformitarianism states what?

Would thought of it? 

Definition
  1. Looked at geological record to determine the Earth'sage.
  2. Charles Lyell
Term
Thomas Mathus stated what about the food resources?
Definition
As population grows their won't be enough food to for everyone.
Term
What were so important about the finches Darwin brought back from the Galapagos islands?
Definition
They had different head and beak structures from how they eat, principle for natural selection.
Term

True or False:

 

Alfred Wallace was published Darwins theory with him.

Definition
True
Term
The Theorys of Natural Selection are?
Definition
  1. Every living thing exhipts variation.
  2. Pop. size increases faster than food supply. (malfis)
  3. Because each pop. has more individuals than can survive, there is competition for resources.
  4. Those individuals that have favorable traits will have an advantage and are more likly to survive.
  5. The environmenal context determines if a trait is bennificial. good one setting, liablity another.
  6. These traits are inherited and therby passed to next generations.
  7. Over long periods of time theose succesful traits acuumlate in later generations, in timecan lead to new species.

EX- wings 

Term
What is the difference between a Primitive/Ancestrial trait and a Derived trait?

Primitive/Ancestral trait is a triat like body hair that is unchanged from ancestorto child.

 

Derived trait like aposibal thumb is a trait that the animanl has developed through the years. 

Term
What is the difference between Generalized and Specialized traits?
Definition

Generalized traits are traits that many different purposes like the 5 digits in the hand.

 

Specialized traits traits only surve one purpose.  Human foot to walk.

What is Evolutionary taxonomy?
Definition

Method used to produce the framework of the tree.

  1.  Groups animals on overall similarites, time is a factor used of the tree of evolutionary taxonmy
Term
Cladistics is what?

not implied relationships of Ancestor and decendents. 

Term
