The bearded pig is normally diurnal, which means it is active during the day like humans, but when migrating within the tropical rain forest, they become nocturnal. Because sight becomes unnecessary when travelling by night, some pigs have garnered other senses like a stronger sense of smell or hearing to keep them safe at night. With climate change and global warming on the rise, the day might soon get too unbearably hot for any animal to stay awake and moving during the day. Since the bearded pig has already adjusted quite nicely to these hot conditions by staying active at nighttime, I believe other pigs have the capacity to do so as well. It would be interesting to study what this evolution could mean for organisms who spend much of their time in tropical rain forests, but the focus should not drift from stopping climate change in the near future.
