Biotic Potential

Always dependent on phenotype

Factors that control population growth

Genetic Drift

Growth Curves

Insufficient biological resources

Logistic Growth (S-Curve)

Emigration

Mutation

Random change in gene frequency from one generation to another

Primates Evolved (60M Years Ago)

Selection

Homo Neanderthal

Resided in Europe

Exponential Growth (R-Curve)

Test 1

1. Food 2. Better medicine 3. Better sanitation

Human Evolution

1. Habitat destruction 2. Hunting 3. Species introduction 4. Disease 5. Hydridzation

Factors: Hiertability and Selection Differential

1. Stabilizing 2. Directional 3. Disruptive

Homo Habilus (2M-1.8 M Years Ago)

Ardiditicus (5 M Years Ago)

Population Regulation

Homo Sapien (350,000 Years Ago)

Enviromental Resistance

Founder effect and bottle neck effect

Test 2

"Road of Homosabiens"

1. Insufficient Food, Water, & Nutrients 2. Disease 3. Predation 4. Competition 5. Insufficient living space 6. Adverse weather conditions

Extinction

Density Dependent mortality

Hardy-Wemberg Equilibrium

3 modes of Natural Selection

Test 3

Homo Erectus (1M Years Ago)

Random change in genetic code

Died out 35,000 Years Ago

Evolution

5 major extiction

Each locus has a different mutation rate

Change in gene frequency from one generation to another

1. Rate of Reproduction 2. Resistance to Adverse Conditions 3. Defense Mechanisms

Cretaceus (65 M Years Ago): Nearly all dinasaurs went extinct

95% Harmful 4% Neutral 1% Beneficial
