What did Darwin notice about the tortoises and finches on the Galapagos Islands?
Darwin noticed that different tortoise species lived on islands with different environments. He realized that the tortoises had traits that allowed them to live in their particular environments. For example, tortoises that ate plants near the ground had rounded shells and shorter necks.
What did Darwin notice about the organisms on the Galapagos Islands?
Charles Darwin in the Galapagos. During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands’ inhabitants.
How are finches in the Galápagos Islands a good example of adaptation?
Answer: A. Each species has a special beak adaptation. Finches in the Galapagos Island are good example of adaptation because these finches have undergone several variations in their beak shape and form according to their ecological niche.
Why are finches important to Darwin’s idea quizlet?
Why are finches important to Darwin’s idea? Each finch has different beaks which are compared to the prey they eat. They helped him discover a new idea. Darwin surmised that all life on Earth was connected, like branches on a tree of life.
Why are finches in the Galapagos islands a good example?
All the finches in the different islands share a common ancestor, which is a group of finches that initially migrated into the islands and conquered the different islands. Due to the different ecologies in the different islands, adaptive radiation of the finches occurred and hence allopatric speciation.
What makes finches in the Galapagos islands a good example of specification?
Answer: D. Explanation: Darwin studied finches on galapagos island, which developed different adaptations (their beak sizes and shapes) due to the availability of different food ( seeds in varying size).
What did Darwin bring back from his voyage?
Groundbreaking discoveries. The expedition visited many places around the world and Darwin studied the various plants and animals, collecting specimens for further analysis. In South America, Darwin found fossils of extinct animals that were similar to modern species.
