Why do we like some animals and hate others?

Cute isn't exactly a scientific term but we all know what we mean by it, don't we? Endearing, adorable, lovable and sweet. So what makes us fawn over a puppy, but run away from rats? Why do we spend millions on trying to keep Giant Pandas alive but spend even more on pushing endangered species like blue-fin Tuna to the brink of extinction by eating them? And if we changed what we classified as cute or ugly, how might that change the battle to protect the Earth's fragile biodiversity?CrowdScience listener Oleksiy, from Ukraine, wanted to know if cuteness is universal and what drives it?
