Darwin's Voyage and Insights on Evolution

Darwin's voyage provided crucial insights on evolution. He observed variations among island species, such as Galápagos tortoises and finches, showcasing adaptations for survival. The species' ability to adapt to their environment through genetic changes was evident. Darwin also discovered fossil and geological evidence supporting an ancient Earth in his exploration.

  1. KEY CONCEPT Darwin’s voyage provided insight on evolution.

  2. Darwin observed differences among island species. • Variation is a difference in a physical trait. • Galápagos tortoises that live in areas with tall plants have long necks and legs. • Galápagos finches that live in areas with hard-shelled nuts have strong beaks; those with long beaks live in areas with cactus flowers

  3. Species are able to adapt to their environment. • Adaptations can lead to genetic change in a population. • In Galapagos, the flightless • Cormorant used to have to fly • To obtain food but now, it has no natural predators and swims and dives for fish therefore does not need its wings and is flightless • An adaptation is a feature that allows an organism to better survive in its environment.

  4. Darwin observed fossil and geologic evidence supporting an ancient Earth. • Darwin found fossils of extinct animals that resemble modern animals (below is Glyptodon which is present day armadillo)

  5. Geological evidence: • Darwin’s observations from land, sea and fossil evidence.
