This English naturalist sailed on HMS Beagle and later proposed that species change over time through a process he called "descent with modification."
The process where organisms better adapted to their environment tend to survive and produce more offspring is called this type of selection.
These preserved remains or traces of ancient organisms found in rock provide direct evidence of life forms that existed millions of years ago.
When farmers breed dogs or cattle to enhance desirable traits over generations, they are practicing this type of selection.
This molecule carries genetic information from parent to offspring and contains the instructions for building proteins in all living things.
When a random change occurs in an organism's genetic code, potentially creating new traits that can be inherited, this is called a what?
Species that share a common ancestor and have similar bone structures, like the arm bones of humans and whales, are said to have these types of structures.
A feature that helps an organism survive and reproduce in its environment, such as a polar bear's white fur, is called this.
