Without these colors, the birds would not be aware that these butterflies contain cyanide, and the defense mechanism would be useless. The students were asking many questions after reading. The parasite takes over the snail's body and mind to turn it into an organism that will attract birds, the parasite's second host.

Hybridization can increase genetic diversity in some cases, said Tallmon. Polar bears, on the verge of extinction due to climate change, are frequently moving inland in search of food and mating with grizzly bears to create a hybrid animal that is more resilient to the warming world. Warmer temperatures have allowed grizzly bears and polar bears to venture to habitats they dont usually occupy and mate to form a hybrid: the pizzly or grolar bear. Considering that human activity has indirectly brought together species through planetary warming and increased fossil fuel emissions, the question on the minds of many biologists like Arnold is whether humans should play a role in preventing hybridization like this. 0000001343 00000 n The rate at which humans are driving species to extinction is 1,000 times faster than the rate at which animals would go extinct naturally, Pimms research shows.
