Charles Darwin’s well-known theory of evolution has been questioned by a new study that was published in the journal Biology Letters, “Links between global taxonomic diversity, ecological diversity and the expansion of vertebrates on land,” by Sarda Sahney, Michael Benton, and Paul Ferry from University of Bristol concluded that it was “living space” rather than “competition” that is the main driving force for evolution.
In the famous theory of English Naturalists on evolution, that was published in his 1859 book On the Origin of Species., Darwin maintained that it was “competition” that was the main driving force behind evolution. However, the new researchers said that that it is not competition but rather living space that drives species to adopt and to evolve.
Researchers based their analysis on various fossils to study evolution patterns over hundreds of millions of years. The team concluded that it was the availability of space makes the species evolve. They gave the example that when some organisms discovered or developed a skill to fly, it opened a new opportunities for the species to adopt.
“The new study proposes that really big evolutionary changes happen when animals move into empty areas of living space, not occupied by other animals,” according to BBC News.
But according to people who support Darwin’s theory of evolution, the new study is “problematic”. They argue that if species were seeking for a new space to move, this only mean that they are moving on to avoid competition.
