How does adaptation fit into natural selection?
Adaptation and evolution all have to do with how an animal or a species depend on there environment. Adaptation is how the species adapts to there environment.Adaptation is caused by evolution by natural selection.
True or false Darwin observed variations among individuals within a population but he did not realize that these variations were caused by selective breeding?
True, Darwin did realize that the observed variations among individuals within a population were caused by selective breeding. Although he did do a lot of great stuff. He wrote a book called The Origin of Species. You should check it out if you would like to find out the stuff that he did and what he found out about evolution. Either that or rent a book from a library about evolution.
Why do artichokes have pointy needles in the leaves of their exterior?
Natural selection was probably the culprit, but what event/animal caused it to evolve into a plant with splkes for defense, I do not know.
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).
The highest rate of natural selection would probably occur when?
This would occur when organisms showing many genetic differences caused by mutations and genetic recombination reproduce in a changing environment.
What problems can be caused by selective breeding chickens?
the color of the yolk
What caused the zebra to originate?
Natural selection.
What is selective breeding cause by?
Selective breeding is caused by humans, we created selective breeding by finding out that if we mate two lions one with white lion gene (and white fur) and one with out the gene (with normal fur )there is a good chance that a white lion may be born but also a good chance a normal lion may be born
What isn't an example of selective breeding?
Selective breeding is when people (scientists) breed plants/animals for their traits. Its like strong horses being bred together or like white and red flowers to make pinks flowers. They can predict what the organism will turn out to look like. An example that ISN'T selective breeding is random flowers/animals that breed not caused by humans.
Is descent with modification caused by natural selection?
No, it's the other way around: descent with modification is what you need for natural selection to happen.
Pesticide resistance in mosquitoes is an example of?
accelerated rates of natural selection due to human involvement.. natural selection caused by human intervention.
Selective breeding tomatoes?
Selectively breeding tomatoes have caused many people to become upset over things like increased price. These people are also disappointed that the taste is not good for example.
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.
How does the theory of punctuated equilibrium differ from natural selection?
They describe different things, so they cannot really be compared. Natural selection is the mechanism that gives direction to evolution. Punctuated equilibria is a model for the varying rates of adaptation caused by natural selection.

What mechanism did Charles Darwin believe caused evolution?
Natural Selection is what Darwin believed was the cause of evolution.
