How did tortoises and birds differ among the islands of the Galapagos?
How did tortoises and birds differ among the islands of the Galapagos? The tortoises on the Galapagos Islands all had different shaped shells; therefore they were different species of the same category of tortoises.Darwin found several types of small, ordinary brown birds. Most of them had differently shaped beaks.
Can turtles live up to 500 years?
According to the Turtle Conservation Society, most turtle species live from 10 to 80 years. But sea turtles and large land tortoises can live to be much older. Their lifespan can be 150 years or more.Some have estimated, however, that large turtles may be able to live 400 to 500 years!

Jonathan, a Seychelles giant tortoise living on the island of Saint Helena, is reported to be about 189 years old, and may, therefore, be the oldest currently living terrestrial animal if the claim is true. Harriet, a Galápagos tortoise, died at the age of 175 years in June 2006.
