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
What did Darwin hypothesized that the different finches on the Galapagos islands all had a what?
a common ancestor
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.
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.
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
Darwin believed that the various species of finches on the Galapagos Islands came from one common ancestor He believed they evolved by?
adaptive radiation
What observations did Charles Darwin make about the finches in the galapagos islands?
he saw that in the different places and things the finches ate made their beak a different size and shape to adapt to their surroundings
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.
Which features of galapagos finches was important to Darwin in development his theory of natural selection?
Basically, the variation in beak size that indicated the birds radiating out from a common ancestor to finding many niches for food acquisition.
What happened to the ancestor of the honeycreeper when it left the mainland and encountered the diverse niches of Hawaii?
It radiated adaptively into many new species. This is common when a species encounters diverse niches of Island groups. See Darwin's finches.
What species did Darwin find on the Galapagos Islands?
Geographic isolation of a common ancestral species of finches
Who was it that proposed that all living things came from a common ancestor?
Charles Darwin
