Natural Selection
Eliminates the extremes and favors the more common characteristics
Stabilizing selection
They evolve in order to survive in their natural habitats
Why do species evolve?
Abiotic is anything not living and biotic is anything living.
What is the difference between Abiotic And Biotic?
When two dissimilar organisms live together and one or both are affected by the relationship
symbiosis
Regulation
Carrying oxygen throughout the body, removing waste
Disruptive /diversifying selection
increasing the extremes creating 2 different types
Does evolution affect a single being or a population?
Evolution can only affect a whole population over years
Predator and prey
What are the 2 organisms a part of a predation relationship?
Mutualism, Commensalism, and Parasitism
Interactions
Temperature, pH
Homeostasis
Directional selection
shifts from one type to another
Charles Darwin
Who “discovered” the theory of evolution?
What are the 2 types of competition?
Interspecific Competition and intraspecific competition
A symbiotic relationship in which one organism benefits, while the others neither benefit or are harmed.
Commensalism
Capture energy, energy from food
Energy processing
Based on variation in sexual traits (sexual dimorphism)
Sexual Selection
In an evolution tree, what tells you how related 2 species are?
How close their most common ancestor is.
Mutualism,commensalism,And parasitism
What are the 3 symbiosis relationships between Organisms?
Mutualism
Both organisms in the relationship benefit from each other.
Movement away from stimulus
Negative reaction
Breeding plants or animals to create new versions
Artificial selection
Natural selection Genetic Drift, Bottleneck effect, Founder effect, Gene Flow,Changes in DNA,Nonrandom mating.
What are 3 causes of evolution?
What are the Levels of Ecological Organization?
Organism (Individual),Population, Community, Ecosystem, Biome, Biosphere
In which one organism benefits, while the other is harmed.
Parasitism
Plants growing toward the light
Sensitivity or Response to the Environment
