When Charles Darwin saw the different species of finches on the Galapagos Islands, he recored many hand drawn pictures of them. They differed in beak style. Some had beaks better suited for pecking bugs out of trees, while others were better at picking them out of the ground. His explanation for the differences was that they evolved over time to adapt better to their surounding and to have a greater chance of surviving. This was his theory of Natural Selection. Hope this helps. Lily When Charles Darwin saw the different species of finches on the Galapagos Islands, he recored many hand drawn pictures of them. They differed in beak style.

What discovery lead Charles Darwin to develop his theories on adaptation?
finches on the Galapagos islands, darwin noticed that on different island each beak of the finch was different depending on the food avalible on the different islands so darwin presumed that as each finch moved to these islands their beaks changed
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.
What island did Charles Darwin go to discover finches?
Since Darwin found many species of plants he found many species of finches. Those species, just like the warbler finch, were found on the Galapagos Islands.
How do Darwin's finches exemplify speciation?
Darwin was puzzled about the many adaptations of the finches on the Galapagos Islands
What did Charles Darwin observe im the finches?
their beakes were adaptationsrelated to the foods the finches ate
What specific differences about the finches on the galapagos islands were of great interest to darwin?
beak structure
What Did Charles Darwin study in the Galapagos?
he studied the differences in finches of the three galapagos islands.
What specific differences about the finches on the galapagos islands were of great interest to Darwin's?
beak structure
WHAT SPECIFIC DIFFERENCES ABOUT THE FINCHES ON THE GALAPAGOS ISLANDS WERE OF GREAT INTEREST TO DERWIN?
The shapes of their beaks were different from mainland finches and they worked better to get the food they needed.
What was significant about the organisms Darwin observed on the Galapagos Islands?
because he discovers the differences between the variables of finches
Why did Darwin say finches on the Galapagos islands new species of finches?
That they were evoled from on specie of finches.
Where are finches found?
The Galapagos Islands.
Are finches in Galapagos islands similar?
No, evolution has created different species of finches on the Galapagos Islands. There are 15 different species that are found on the Galapagos islands.
Darwin observed that some finches had larger beaks than other finches in the population on the Galapagos's islands what does this obsevation illustrate?
The finches adapted to their available food on each island. If they ate only insects within trees, their beaks were long and pointed. If they ate seeds with a hard shell, their beaks became short and powerful. Darwin proved his theory of evolution based on the differences he observed among the finches on the different islands.
Why was Darwin interested in finches?
The Galápagos Islands had finches that once shared a common ancestry. Darwin found that finches on one island had, over many generations, developed and adapted in differing ways to finches from other islands.
What animals were examined by Darwin on the Galapagos islands?
the animal Darwin examined were finches on the Galapagos islands (at least finches were the main thing he studied)
What bird Charles Darwin breed to test his theory?
Galapagos finches
