Was Darwin Wrong?

Until now Charles Darwin's concept of natural selection and survival of the fittest has been the key to the evolution of all living things. But a new study by researchers at the University of Bristol in England suggests "living space" is responsible for evolutionary patterns throughout history. Using fossils to focus on land animals, the research team suggests that animals have survived more easily in favorable environments that offered more food and less chance of being hunted and eaten by other animals.

At Yale University in Connecticut, evolutionary biologist Stephan Stearns isn't convinced by the study findings. "Why would they move if everything was comfortable where they were? So, competition probably is one of the things that drove them into the new environment," he said. "Well, going somewhere else is always a challenge, because wherever you have been, you're always pretty well adapted to that, and the only reason to go somewhere else is if the conditions here are deteriorating." Over time conditions are probably going to be deteriorating because other organisms are evolving to be better at extracting resources from your environment than you are, or they're evolving to be better at eating you. Stearns explains the concept of "living space" doesn't only relate to a location or a physical place where animals live.

By "living space" its not really about the geography but the community. For example you can't really have squirrels without trees right?

This is related to biology because this talks about how Stearns has an alternative theory saying that what Darwin said about natural selection and survival of the fittest was all wrong. Stearns said that "living space" could be a possible key to evolution. This is also very important because all we have been learning through text book is Charles Darwin's theory and how his theory of evolution is they way all living thing became the way they are. But what if all we're learning about Darwin is all wrong. And that this theory of "living space" could be the key to our evolution.
