Rock forming minerals, such as calcium carbonate, in water filled in the small spaces in the tissue of pieces of wood petrified wood. Water can replace tissues, this type of fossil can preserve internal structures of an organism.
Mineralization

Limited resources can lead to __________ over food, mates, and habitats.
Competition

Selective Breeding
A giraffes long neck enables it to reach the leaves in tall trees. What type of adaptation is this an example of?
Structural
Consider the wings of a bat and the wings or an insect, which term best describes these structures?

Explain the Theory of Evolution
A scientific theory that explains how organisms change over time.
Explain why reproduction is important when talking about adaptations of a species.
Favorable traits will be passed from parent to offspring. This will increase the species chance of survival.
Give an example of a functional adaptation (biological process that helps an animal survive)
Webbed feet
Large ears
Oily Feathers
Stream-lined body
Body parts of organisms that are similar in structure but differ in function are know as ________ structures.
Homologous
Describe trace fossils. What can we learn from this type of fossil?
Trace fossils provide evidence of the speed and weight of a dinosaur.
Darwin formulated his Theory of Evolution by natural selection based on the observation that food is a limiting resource. What did he mean by that? Think about the Galapagos tortoises when explain your answer.
Species that have favorable adaptations will find and eat food first. These animals will pass on favorable traits to the next generation.
Explain selection.
Over time, the successful trait is passed down from generation to generation wiping out the unsuccessful trait.
What is an adaptation?
A characteristic that better equips an organism to survive in its environment.
Explain how a sudden and drastic environmental change might lead to the extinction of a species.
