How did the finches help Darwin to formulate his theory of natural selection and evolution?

There were many islands and finches on each. The finches did not fly from their home island to other islands. Different islands had different food for the finches. Darwin noticed that where there were plenty of honeysuckle flowers for the birds to feed on, the finches there had long beaks. On islands where the best bird-food
was small seeds, the finches had beaks more like canary beaks, short and strong.
Darwin also noticed that the finches were all from the same original flock and had probably mixed up when the islands were closer together and they could fly to any island to feed.
So Darwin concluded that when the finches became isolated on different islands, their beaks evolved to be most suitable for eating the food available. The birds with the wrong beaks died young and had few chicks and these chicks unfortunately for them inherited their parents silly beaks. The birds with the right beaks fed well and had lots of chicks who
inherited good beaks. So eventually nearly all the finches on any given island had the most suitably shaped beaks.

Can natural selection exist with out evolution?
Perhaps not, but evolution can exist without natural selection.
What body part of the Galapogos finches appears to have modified by natural selection?
The finches beaks were modified by natural selection. The beak size and shape varied from island to island.

In evolution, natural selection is often called survival of the fittest.

Random processes are not part of the theory of evolution by natural selection.
The different species of finches on the galapagos island are believed to have arisen as a result of natural selection acting on populations of finches that had experienced?
Evolution
Which 2 scientist demonstrated that natural selection is still at work in the evolution of finches?
Rosemary and Peter Grant.
The similarities in the Galapagos finches implied?
The Galapagos finches only exist on the islands and inspired Charles Darwin. They implied that evolution occurs through natural selection.
Darwin began to formulate his concept of evolution by natural selection after what?
observation of many species and their geographical locations.
What scientist besides charles Darwin developed the theory of evolution?

No, natural selection is believed to result in evolution.
Can natural selection exist with out evolution?
Perhaps not, but evolution can exist without natural selection.
How is natural selection and evolution linked?
Natural selection is one of the 'guiding' principles of evolution.
