The difference in water temperature will lead to the emergence of new species of sea creatures.

Researchers studied the DNA of several bulls that live in coastal areas. Experiment

showed that the genomes of populations living in different areas are affected by the difference in water temperature.

Each regional population of bulls alreadyadapted to their preferred thermal habitat, and migrants scattered in too warm or too cold nearby regions will prosper less than the populations already settled into them.

The discovery calls into question the assertion that new species can develop only in an isolated environment, the study notes.

Previously, ornithologists from the University of Groningen found out that the increase in global temperature will harden the birds - birds will behave more aggressively during conflicts over food and near nests.
