What else can I help you with?
What had different shaped shells depending on the island they were from?
Galápagos finches had differently shaped beaks depending on the island they were from.
Had different shaped shells depending on the island they were from?
The Galapagos Islands. Charles Darwin discovered that the birds on the island, finches, had different beaks. The finch's beak varies from each island to help the finch eat the food they can find on the island
What did Charles Darwin notice about the island animals of the galapagos island vs mainland animals?
The finches beaks all were different sized,shaped,and fuctions.
The species of finches that Charles Darwin found on the galapagos island displayed different stuctunal adapatations one of the adapatations Darwin noted was the what?
different shaped beaks
Why did Darwin think that the finches looked different on the various islands?
The different finches have different shaped beaks.
How Darwin's Finches provide evidence for evolution?
the beaks were different on every island
Why do birds have different mouth parts?
Different birds require different beaks and mouth-parts depending on their diet. Birds that eat meat need heavy, powerful beaks, nectar-feeding birds need long, thin beaks, etc. Beaks can also be used to attract a mate.
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.
Bird's with strong cone-shaped beaks can crack what to eat them?
Birds with strong cone-shaped beaks can crack open seeds and nuts to eat them.
What are the different parts of the mouth?
Bills or beaks are the type of mouthpart that a bird has. The beak is shaped in a way for the type of food that the bird eats.
How did the beaks of galapagos finches differ from one island to another?
With evolution the beaks transformed into long beaks for eating bugs and short beaks for eating seeds
How did the beaks of Galapagos finches differ one island to another?
With evolution the beaks transformed into long beaks for eating bugs and short beaks for eating seeds
