How Life Adapts to Its Environment

If on Earth there's one thing we've done well, it's in the many ways we've adapted to our environments. If "Jurassic Park" taught us anything, it's not to stay out of the long grass, it's that life finds a way. Earth is home to an abundance of life, from microscopic bacteria to towering redwood trees, and from the highest mountain peaks to the deepest sea trenches. Survival means competing for food and space, especially where both are scarce. That's where things get interesting.

Charles Darwin theorized about how life finds a way—by gradually adapting its structure or behavior to suit its environment—in "On the Origin of Species". As part of evolution, adaptation can take millions of years, but it can also happen over just a few generations. Here are some of the most interesting ways that life on Earth has adapted to its habitat.
