1. Overproduction - more offspring are born than survive
2. Genetic Variation - there is variation in the population
3. Struggle to Survive - organisms with suitable variations will survive and reproduce
4. Differential Reproduction - suitable variations are passed on to offspring

∙ 11y ago1. the individual organisms that make up a population vary in the traits they possess, such as their size and shape.
2. some of the trait differences are heritable, meaning that they are passed on to offspring genetically.
3. in each generation, many more offspring are produced than can possibly survive. thus, only some individuals in the population survive long enough to produce offspring and among the individual that produce offspring, some will produce more than others.
4. the subset of individuals that survive best and produce the most offspring is not a random sample of the population. instead individuals with certain heritable traits are more likely to survive and reproduce. natural selection occurs when individuals with certain characteristics produce more offspring than do individuals without those characteristics. the individuals are selected naturally - meaning by the environment.

What is the 4 main points of natural selection?
natural selection (4 tenants) -genetic variation -overproduction of offspring -struggle for existence (competition) -differential survival and reproduction
What causes the allele frequencies to changes?
1. Mutation 2. Migration (Gene Flow): both immigration and emigration. 3. Genetic Drift 4. Sexual Selection (Non-random mating) 5. Natural Selection: those most fit survive to pass on their genes to the next generation.
What is the mechanism that allows organisms to evolve?
1) Natural Selection 2) Climate changes 3) Geographical events 4) Radiations of organism into new habitats 5) Changes in ecosystem 6) Changes in continental position Above are mechanisms of selection, the environment, basically. Mechanisms of evolution are; mutation, gene flow. genetic drift and most importantly for adaptive changes, natural selection
When will natural selection occur?
when there is competition
What are four requirements for natural selection?
Natural selection occurs when four conditions are met: 1. There is variation among individuals. 2. That variation is at least partially heritable. 3. That variation is linked to differential reproductive success. 4. More individuals are born than can survive and reproduce.

How would you describe the four key principles of natural selection?
Well, the 4 key principles of Talamarianism contribute to natural selection in very different ways. The first contributes by melting flesh. The other 17 are Melissa and Jim's children, therefore they are not immune to freshly cut grass.
What are the 4 mechanisms by which evolution can occur?
genetic drift, mutation, natural selection, and migration
