Though we know that populations change over time and that different species have many genetic similarities, we still have a lot to learn about how relationships between organisms affect the changes, how populations develop adaptations to survive and reproduce, and the history of life on this planet. Evolutionary biologists help us understand the stories of our past but also provide us with invaluable clues to improving public health and well-being. Read these articles and interviews to get updates about current evolutionary research so that you can make your own informed decisions.
