What are the different types of beaks?
there are hard bird beaks and soft donkey beaks specify which type you want they have razor sharp beaks.
Which feature of galapagos finches was important to Darwin in developing his theory of natural selection?
Darwin noticed that the finches in the Galapagos Islands had different types of beaks. He concluded that this meant they must have evolved these beaks, so that each type could find food.
What observations were made about the finches on the Galapagos island?
Firstly, they aren't true finches. They were collected by Darwin on his second voyage. The main observations are there beak shapes and sizes. Depending on their location in the islands, the finch's diets vary and then because of their varying diets they have varying beaks which have adapted to their food sources. The variances in the finches and their beaks despite all living in the same island chain spurred Darwin's theory of evolution. Since Darwin's time there have been many expeditions to the Galapagos Islands and new discoveries have been made such as the Large Cactus Finch males have two different beak types. Those with the shorter beaks have one distinct song and those with longer beaks have a different distinct song. They both feed on the same type of cacti, but in different ways due to their beak types. It's thought it's so the birds can all still feed when the food is scarce.

How did ideas from scientists before Darwin influence Darwin's ideas?
Darwin was an English Naturalist. His first ideas for his theory came from his trip around the world on the Beagle. His first evidence was when he was in South America and he discover fossils of a form of giant armidillo. They were similar, but not identical to the living armidillos. He also spent some time in the Galopagos Islands where he discovered a type of finch, but they had diffirent varieties of beaks. And he found another finch extremely similar to it in South America. Darwin also had his own experiences with evolution, he was a pigeon breeder. He was also influenced by the following scientist and their discoveries: Jeane Baptiste Lamarck Georges Cuvior James Hutton Charles Lyell Thomas Malthus Darwin then mushed all of his ideas to his theory and worked with a young scientist Alfred Russel Wallace. After Darwin wrote his book. I learned all this in my biology I took in 7th grade.
