What are the islands where Charles Darwin observed variation among organisms?
Galapagos Islands are the islands where Charles Darwin observed variation among organisms.
What did Charles Darwin discover about variation from his study of the finches?
charles Darwin was an amazing person
In what way were Darwin's observations regarding living things and fossils and his observations about ostriches important?
Darwin's observations regarding ostriches led him to the theory of Evolution. For example, when he visited one part of Argentina, he noticed that the ostriches were similar, not the same, to ostriches from another region of Argentina. The fossil record also mimicked this loosely. Thus, Darwin began to look for a viable theory that could answer this. Hence, the theory of Evolution was born, which made the scientific explanation for life as we know it today. I hope this answers your question.
What is variation under domestication of Darwin?
Artificial selection.
Why was variation the weakest concept in Darwin's theory?
Variation?!?! That was an obvious observation of naturalists that opposed Darwin's concepts totally. Unless you mean the heritability that leads to variation? Explaining that variation was the problem. Creationists of the time explained this by positing god's whimsy in designing his species, but this was shown to be nonsense as natural processes are at work in variation and this can be shown experimentally. The concept of natural selection explained how that natural variation was selected on beneficial traits. What Darwin did not understand is how that variation was passed on to progeny. His explanation was wrong.
What is one example of biological variation that Darwin observed in his travels?
plant
What animals did Darwin use to show variation in domesticated forms?
monkey

How did Charles Darwin explain inherited variation and artificial selecton?
Darwin said that artificial selection was when nature provided the variation, and humans selected those variations that they found useful. Inherited variations are differences that are passed from parents to offspring
The weakest concept in Darwin's theory was variation why?
I think it isn't a weak or invalid concept.
Who observed variation in the characteristics of animals and plants on the different islands of Galapagos?
Charles Darwin
How could the different types of tortoise have evolved according to Darwin's theory?
Through reproductive variation and differential reproductive success (ie. variation and selection).
