How Life Adapts to Its Environment

This learning path has been created for you.
Playlist Description

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.

Scientists have made a biological discovery in Arctic Ocean waters as dramatic and unexpected as finding a rainforest in the middle of a desert. A NASA-sponsored expedition punched through three-foot thick sea ice to find waters richer in microscopic marine plants, essential to all sea life, than any other ocean region on Earth. The discovery is the result of an oceanographic expedition called ICESCAPE, or Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment. The NASA-sponsored mission explored the seas along Alaska's western and northern coasts onboard a U.S. Coast Guard icebreaker during the summers of 2010 and 2011. The finding reveals a new consequence of the Arctic's warming climate and provides an important clue to understanding the impacts of a changing climate and environment on the Arctic Ocean and its ecology.

Many different types of species hibernate, and they all do it a little bit differently. Many bears hibernate, but for some reason, polar bears do not. Why is this? Trace explains why polar bears don't need to hibernate, and also explains how hibernation works in a few different species. Read More: Why Polar Bears Don't Need To Hibernate http://www.futurity.org/polar-bears-survive-arctics-icy-blasts/ "Brown and black bears hibernate during winter to conserve energy and stay warm. But the same isn't true for polar bears." Polar Bears Exhibit Genome-Wide Signatures of Bioenergetic Adaptation to Life in the Arctic Environment http://gbe.oxfordjournals.org/content/early/2014/02/06/gbe.evu025.abstract "Polar bears (Ursus maritimus) face extremely cold temperatures and periods of fasting, which might result in more severe energetic challenges than those experienced by their sister species, the brown bear (U. arctos)." How Hibernation Works http://science.howstuffworks.com/zoology/all-about-animals/hibernation.htm "Every living animal on Earth is burning energy all the time." Hibernation and Denning http://www.polarbearsinternational.org/about-polar-bears/essentials/hibernating-and-denning "Hibernation. Polar bears do not overwinter in dens like brown and black bears." The Great "Do Bears Hibernate?" Debate http://www.slate.com/articles/health_and_science/animal_forecast/2013/02/do_bears_hibernate_polar_bear_black_bear_grizzly_bear_sex_and_torpor.html "Bears hibernate. They spend all year eating salmon, blueberries, and picnic baskets and then, sometime around baseball playoffs, they all wander to a cave full of treasure and explorers' skulls where they curl up in a big furry ball and snore away the winter." Polar and brown bear genomes reveal ancient admixture and demographic footprints of past climate change http://www.pnas.org/content/early/2012/07/20/1210506109 "Polar bears (PBs) are superbly adapted to the extreme Arctic environment and have become emblematic of the threat to biodiversity from global climate change."
