1. Evidence for Evolution
Fossil= any remains of life from an earlier time.

2. Types of fossils
·  Imprints- Imprint of a leaf, feather, or organism in rock.
·  Molds- is a fossilized impression made in any material - a negative image of the organism
·    Casts- made of minerals that filled the hollows of an animal track, mollusk shell, or other parts of an organism.
·    Petrified- A piece of wood or bone replaced by minerals.
·    Amber- An insect or other organism trapped in plant resin.

3. Here's a general flow chart of fossil formation:                                                                  

4. Sedimentary rock
A rock type formed by mud, sand, or other fine particles that settle out of a liquid.
The layer that contains the most fossils.
Examples of sedimentary rock: limestone, sandstone, and shale
Fossils are most commonly found in limestone.

5. Other evidence for evolution
Homologous structures- Traits that are similar in different species because the species share a common ancestor
How are the human arm, whale fin, and bat wing similar?
All three organisms have bones for the forearm and digits.

6. Vestigial structures
           Vestigial structures- Inherited structures that are reduced in size and are often unused.
·      Suggest structures that once functioned in an ancestor
·      Example; Pythons have vestigial hip and leg bones which indicates a legged ancestor.
·      Examples: Human appendix, a tiny dead-end pouch on the intestine that may play a minor role in the immune system. The Muscles that move the ear.

7. Analogous structures
        Analogous structures-Those structures that are similar in function, but not inherited from a common ancestor.
 What are some examples of these types of structures?

8. Embryological development
In early development, tails and gill slits are found in fish, rabbits, birds, and mammals.

9. DNA
Scientists can determine if an organism is related to another organism by comparing their DNA.
Organisms that are close relatives have similar DNA.
Dogs are the closest relative of bears
Genetic evidence shows that all Primates (including us) evolved from a common ancestor

10. Camouflage vs. Mimicry
Adaption for defense in which one organism blends into it’s surrounding
Resemblance of one organism to another, this is also used as a defense.
