Natural Selection of Sea Turtles
Hi! My name is Carl. And I'm about to show you the process of natural selection, created by a man named Charles Darwin.
This is my mate, Agatha, and as you can see, I have a lot of offspring! During Step 1 of natural selection, all of the animals are sex-crazed and want to make lots and lots of offspring. This plays a role in how many of the offspring will survive and how many will die. I have 11 kids right here, and unfortunately, not all of them will make it.
Step 1: Overproduction of Offspring
Agatha and I have many kids, 11 to be exact! And as you can see, we have many different types of turtles. We have kids that look like me, kids who look like Agatha, and kids who are both colors. Our family varies, but unfortunately that means that some will not make it.
Step 2: Variation
Step 3: Selection
Unfortunately, Agatha and I lost 6 of our 11 children. The ones that survived are the ones that look like me and my mate. The ones who died were two colors, providing contrast for predators, such as seabirds. The ones that look like me blend in with the sand, and the ones that look like Agatha blend in with the foliage on the shore. We have been selected to survive!
Step 4: Adaptation
And that is the process of natural selection! Pretty cool, isn't it? I hope you enjoyed learning about the four steps that coincide with natural selection. Thank you!
As I said previously, our children have adapted to survive where we live, mainly through camouflage. But they also have the hard shell on their back to protect them from other predators. Our children are very lucky!
