Timing and coordination of behavior are regulated by various mechanisms and are important in natural selection.
Individuals can act on information and communicate it to others. Innate behaviors are behaviors that are inherited. Learning occurs through interactions with the environment and other organisms.
Responses to information and communication of information are vital to natural selection. In phototropism in plants, changes in the light source lead to differential growth, resulting in maximum exposure of leaves to light for photosynthesis. In photoperiodism in plants, changes in the length of night regulate flowering and preparation for winter.
Behaviors in animals are triggered by environmental cues and are vital to reproduction, natural selection and survival.
Examples:
- Hibernation
- Estivation
- Migration
- Courtship
Cooperative behavior within or between populations contributes to the survival of the populations.
Examples:
- Availability of resources leading to fruiting body formation in fungi and certain types of bacteria
- Niche and resource partitioning• Mutualistic relationships (lichens; bacteria in digestive tracts of animals; mycorrhizae)
- Biology of pollination
Students should be able to:
LO 2.38 Analyze data to support the claim that responses to information and communication of information affect natural selection.
LO 2.39 Justify scientific claims, using evidence, to describe how timing and coordination of behavioral events in organisms are regulated by several mechanisms.
LO 2.40 connect concepts in and across domain(s) to predict how environmental factors affect responses to information and change behavior.
