|
|
Term
| Process by which fossils are made |
|
Definition
1. Petrifaction- the proces of taking a living organism and having minerals replce the livin cells.
2. Amber- hardened tree sap that insects get stuck in.
3. Mold- preserving the shape of an animal
4. Cast- the imprint of the mold |

|
Term
| Principals of evolution by natural selection |
|
Definition
1. Variation- different charateristics in individuals in any species that may be helpful
2. Overproduction
3. Competition
4. Adaptation- come from variations; they help organisms survive and reproduce. They are inherited traits that help an organism in a given envirnment
5. Natural selection- the envirnment chooses the best adaptation to survive and reproduce
6. Speciation- favorible adaptations gradually accumulate and over time new species are formed |

Definition
p2+2pq+q2=1
2pq=Heterozygous
q2=homozygouse recessive
q=recessive trait

Definition
| The process by which a species evolves into a number of different speciations that occupy dfferent enviornments |
|
|
Term
|
Definition
| Organisms not closley related obtain similar adaptations and resemble eachother |
|
|
Term
|
Definition
| When related species live in different envirnments and become diffenciated; begin to develop homologous structures |
|

| a geographical barrior seperates species |
|
|
Term
|
Definition
| isolation from within the same geographic barrior |
|
|
Term
| Geographic isolating mechinisms |
|
Definition
| sympatric and alopatric isolation |
|
|
Term
| Reproduction isolation: Pre Mating |
|
Definition
-Mechanical isolation: organisms are anitomiscly incompitant
-Temporal isolation: heat at different times of the year seperates species
-Behavioral isolation: different mating protocal (ie mating songs/ dances)
-Gametic isolation: sperm cannot fuse with the egg
-Habitat isolation: some organisms live in the same area but within different habitat |
|
|
Term
| Reproductive isolation: Post mating |
|
Definition
-Reduced offspring viability: embryo may be aborted
-Reduced offspring fertility: offspring may be vigerus to themselves, but may be unable to produce functional gamates
-Hybrid breakdown: one generation is fine, but the next becomes weak and substanant generations become weak and sterle |
