What idea of Darwin based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generation?
Natural Selection
What idea of Darwin's based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generation?
Natural Selection
The process by which an organism grows and changes over time?
(The fact of) Evolution. The fact of evolution applies to individual organisms and can not be refuted.
How does natural selection help to change organisms overtime?
Natural selection varies the death rates of individuals in the current generation. As the next generation is born with different traits derived from parents that were survivors of the current generation, the population changes gradually from generation to generation better able to survive longer against the natural selection pressures. Should selection pressures change in the future (and they very likely will) the direction of changes caused by natural selection will also change (with a corresponding but temporary increase in death rates if the change is large and sudden).
How changes in the environment affect a community of organisms?
how changes in the environment affect a community of organisms
Natural selection causes changes in populations of organisms not individual organisms because?
differential reproductive success caused by genetic variation is necessary for the process of natural selection.
What is the difference between artificial selection and natural selections?
natural selection occurs due to natural phenomena (e.g. changes in diet or predators).artificial selection occurs due to human generated phenomena (e.g. breeding or domestication).
Is artificial selection or selective breeding a good analogy for the selection that occurs in nature?
It is possible to have artificial selection in nature because of naturally occurring changes in the environment. These changes can greatly modify the organisms in question.
Which physical changes occur in organisms which allow them to be better suited to live in a certain environment?
natural selection is part of this
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

What does Survival of the fittest and natural selection mean?
Survival of the fittest is a not quite accurate phrase for natural selection. Natural selection is, The non-random survival and reproductive success of randomly varying organisms.
The process by which an organism grows and changes over time?
(The fact of) Evolution. The fact of evolution applies to individual organisms and can not be refuted.
How are artificial selection and natural selection similar?
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
