Some animals have long since decided that brains weren’t necessary. BBC Future suggests that sponges evolved to lose their brains over time, as they offered no tangible benefits.
But what about humans? We are the most intelligent species on Earth. We have tamed the natural environment, developed incredible technologies, and settled across almost every corner of the planet. But all this may be exacerbating the problem for other species.
Gonzalez-Suarez says: "It is our collective responsibility as scientists who study megafauna to act to prevent their decline." Time to put our big brains to good use.
