Innate Behavior: Reflexes, Kineses and Taxes

1. Innate Behavior: Reflexes, Kineses and Taxes

Innate behaviors are inherited and humans and other living organisms usually engage in them without thinking. Learn about innate behaviors, including reflexes, kineses, and taxes, to better understand the relationship between stimulus and innate behavior.

Learned Behavior: Imprinting, Habituation and Conditioning

2. Learned Behavior: Imprinting, Habituation and Conditioning

Learned behaviors are those that are not innate, and are formed throughout our lifetime. Take a look at the different kinds of learned behavior: conditioning, habituation, insight, and imprinting.

Social Behavior: The Cost-Benefit of Altruism and Kin Selection

3. Social Behavior: The Cost-Benefit of Altruism and Kin Selection

The four main types of social behavior within groups are altruism, selfishness, cooperation and spite. In this lesson, you'll learn about the costs and benefits of social groups, the social behavior of altruism, and how kin selection relates to altruism.

Social Behavior: Agonistic, Dominance Hierarchies, & Territoriality

4. Social Behavior: Agonistic, Dominance Hierarchies, & Territoriality

Although animals do not use words, they can still interact and communicate with one another. Discover the patterns of interaction between animals, called social behavior, with aspects such as territoriality, agonistic behaviors, and dominance hierarchies.

Social Systems vs. Individual Fitness: The Queen/Worker Relationship

5. Social Systems vs. Individual Fitness: The Queen/Worker Relationship

Social systems can improve organism's individual fitness and inclusive fitness. The relationship between the worker bees and the queen is very unique social system. Explore the intricate social system of hives in today's lesson.

The Theory of Demographic Transition: Overview

6. The Theory of Demographic Transition: Overview

The theory of demographic transition describes the changes in mortality, fertility and growth rates within a society. Learn about common demographic terms, understanding population pyramids and the five stages of demographic transition.

Carrying Capacity of a Population: Effect of Biomedical Progress

7. Carrying Capacity of a Population: Effect of Biomedical Progress

Understand the effect of biomedical progress on the carrying capacity of a population. Learn to define carrying capacity and demography, and discover how the carrying capacity of a human population works in terms of biomedical progress.

The Circadian Rhythm
