Genetic diversity is needed to produce viable plants. Scientists are using animal breeding methods to conserve the titan arum

Vampire finches will resort to drinking blood for survival when they can't find other food sources like seeds and insects.

Why Some of Darwin's Finches Evolved to Drink Blood

Scientists suggest the vampire finch evolved to drink blood to survive the volcanic archipelago's harsh environment and scarce resources

Warming waters cause the sharks to hatch early and underdeveloped, making them vulnerable to predation.

Ocean Warming Threatens Baby Sharks in the Great Barrier Reef

Researchers found the hatchlings of the egg-laying epaulette shark are weakened by rising sea temperatures
