A melanosome is an organelle found in animal cells that stores and transports melanin, which is a light absorbing pigment that is responsible for color and photoprotection of animal tissues. The diversity of melanosomes 150 million years ago has provided scientists with interesting information.
How do different species respond to the shifting conditions? That's a good question, and one that scientists have now looked at more closely. They've examined North American mammal responses to human-caused climate change and have found which species are most vulnerable to shifting conditions.
