5.03 Forces of Evolution


Good morning crew and guests!

I am so excited the H. M. S. Beagle has arrived. Quickly gather your gear and prepare to board the ship.  The Captain and crew are anxious to get underway. I can’t wait to find out where they are taking us. Be sure to bring your camera and your travel log this is going to be one amazing voyage.


 In this activity, you will:
  • discover some ways that populations change
  • explore five forces that effect evolution of species and populations

Ahh, nothing beats the early morning salt air. This ship is amazing, isn't it? Charles Darwin spent several years of his life on the Beagle. He sailed around the world observing animals and plants, recording his observations in journals that later made history. Many of the places he visited became quite famous. The Galapagos Islands, for example, was one of the Beagle's ports of call. The animals that Darwin observed there were quite unusual.

Oh, look over there, off of the bow of the boat—dolphins! Aren't they wonderful? These are Atlantic Bottlenose Dolphins, but there are many other types of dolphins that live in these waters. Check out the photos below. Why is there such diversity?

3 different types of dolphins: Pacific white-sided, Atlantic bottlenose, and Pantropical spotted
