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

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

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

Each regional population of gobies is alreadyhas adapted to its preferred thermal habitat, and migrants dispersing into too-warm or too-cold nearby regions will outperform established populations.

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 that rising global temperatures will harden birds - birds will behave more aggressively during conflicts for food and near nests.
