What does evolution mean in science?
Evolution is the gradual change of a population in response to changes in the environment. Evolution does not occur in individuals, it can only occur when a mutation is added to a population or a certain gene is selected for. Evolution occurs because the fittest individuals who pass their genes on the most are the ones best suited for the environment. Those that don't survive don't pass on their traits. It is important to note that fitness described in survival of the fittest pertains to reproductive fitness, not physical fitness.
What scientists argued that variation among individuals allow evolution to occur?
Wallace
What allows natural selection and evolution to occur?
the unequal ability of individuals to survive and reproduce
When does Parasitism occur?
A.Parasitism occurs when individuals of one species-population are used as a resource by individuals of another species-population.
Natural selection cannot occur without what?
Variations within a population. Variations mean traits that only certain individuals have that give the individual a greater or lesser chance of reproducing.
Why can mutation affect evolution?
Mutation is the cause of evolution. Mutation is what creates differences in individuals within a species, leading to diversion. Then "survival of the fittest" can occur.
The smallest unit of evolution is the population?
Yes, populations evolve. Individuals/genes are selected.
Does evolution occur just because an individual organism survives longer in an environment?
No. Evolution occurs because each generation of individuals in a population has slightly different genetics than the one that preceded it and the one that will follow it. There are many different mechanisms that bring these genetic changes about.
Evolution can occur through a variety of mechanisms. what best describes how gene flow can occur?
An individual organism moves into a new population
Explain the difference between adaptation and evolution?
Adaptations refer to changes adopted by individuals whereas evolution applies to changes involving the entire population.
How would you use population and evolution in a sentence together?
Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.Through evolution the population of the species was growing.
Does every factor that effects the reproductive success of only some individuals in a population result in evolution?
yes
