In the early 1800s Darwin studied 13 kings of finches what did Darwin hypothesize about these birds?
The finches were different species that shared a common ancestor
Describe the Grants' hypothesis about how environmental condition led to microevolution among the finches of Daphne Major?
They all came from a similar ancestor of bacteria and that lead to the finches beaks being of certain type and ability to reproduce
Where did Charles Darwin get most of his evidence of evolution?
Observation of finches on the Galapagos Islands.
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 type of birds did Darwin study in the Galapagos?
Famously Charles Darwin studied some finches that he collected when he visited the Galapagos Islands during his voyage on the Beagle. He preserved the specimens he had collected and studied them when he returned to England. He used his observations of the variations in these finches as part of his evidence supporting his theory of evolution. He also studied the breeding of pigeons and domestic poultry.

The evolution of beak sizes in galapagos finches is a response?
how finches use their beaks
Where did Darwin think the Finches ancestor came from?
South America
The evolution of Darwin's finches is an example of what?
speciation
What bird Charles Darwin breed to test his theory?
Galapagos finches
Why were Darwin's galapagos finches so important to Darwin's theory?
It is thought that the finches have a common ancestor. Separated on different islands, each island eventually produced different finches.
Why did Darwin think the finches he observed shared a common ancestor?
tu cola
What did Darwin hypothesized that the different finches on the Galapagos islands all had a what?
a common ancestor
What did Charles Darwin observe about finches on the galapagos islands?
That the finches were similar to the ones on the mainland, but had adapted to the island environment.
In the early 1800s Darwin studied 13 kings of finches what did Darwin hypothesize about these birds?
The finches were different species that shared a common ancestor
The observation by Darwin that finches belonging to different species on the Galapagos Islands have many similar physical characteristics supports the conclusion that these finches?
originated from a common ancestor
