Why would a finch population that lives on an island have a higher rate of speciation that a finch population that lived in a large forest in north America?
A finch population on an island is more isolated than Êa finch population in a large forest. ÊThe gene pool of the island population would be more limited than the genetic possibilities of the finch population in the forest. ÊThe island finches would be more likely to pass on specialized genes than the forest finches. the island finches have more spatial isolation the island finches have more geographical isolation
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
How are the finches on galapagos island similar?
They're birds of the Galapagos Island
What did Darwin observe about the finches on the Galapagos's islands?
That the finches were similar to the ones on the mainland, but had adapted to the island environment.
How geometric isolalation of common ancestral species of finches has led to the development of 14 different species of finches in the galapagos island?
Geometric isolation of common ancestral species of finches has led to the development of 14 different species of finches in the Galapagos Island due to the concept of diversification.
Had different shaped beaks depending on island they were from?
finches
What did Charles Darwin discover about the finches on gaplapagos island?
Answer
Where did all of the finches on the Galapagos's Island originally come from?
the finches originally came from south American main land
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.
Why would a finch population that lives on an island have a higher rate of speciation than an finch population on that lived in a large forest in north America?
Island finches are specially isolated whereas populations that live in large forests aren't. The island finches will have more gene flow.
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 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.
