Molecular Biology
Vestigial Structures
Pharyngeal pouches
Organisms that have the most DNA sequences in common
have the same number of legs
Are the least related
are randomly distributed
Are the most related
A structure that serves the same purpose, but is not made in the same way is called
a vestigial structure
a homologous structure
an analogous Structure
a pheryngial structure
A body part in one organism that is similar in function with the body part of another is called a
homologous structure
analagous structure
vestigial structure

What do they think happened to the dinosaurs?
They were drowned in a great flood
They were killed when the Earth got too hot
They were killed when it got too cold and the plants they ate died
A meteor hit the earth and caused a temperature change they could not adjust to
What can happen to organisms when their environment changes?
Move
Adapt
Die
All of the above
What is a mutation?
It's when an organism adapts to its environment
It's when the offspring of two parents is different from each parent
It's when the genes mix to create a new combination
It's when the DNA sequence changes due to a mistake when it divides during mitosis or meiosis
