I've always thought that about pandas. They dont have a mating instinct and have a very difficult diet in terms of effort required per calorie.
And they're going out of business. Isn't that evolution?
- Bartweiss 9y agoAn interesting read on this: https://np.reddit.com/r/todayilearned/comments/3azkqx/til_naturalist_chris_packham_said_he_would_eat/cshqy9y/?context=3 https://np.reddit.com/r/todayilearned/comments/3azkqx/til_na... The short version - pandas are just find for their habitats, and aren't going out of business. The traits of pandas sound odd, but they're actually common to lots of highly-successful animals. They mate just fine in the wild and are bulk feeders that can easily consume lots of low-efficiency food. Their population hasn't been in any kind of steady decline, but has plummeted twice, each time when large portions of their habitat were destroyed.

- sandworm101 9y agoThey mate fine. Most of the problem has been linked to their zoo habitats, at least in the west. They were so precious that they weren't given the climbing structures (ie trees) to properly exercise in case they fall. The Chinese give them lots of climbing exercise and are breeding them just fine. Give humans too much food and no exercise and they stop breeding too.
