I do have to wonder how plants could have rebounded from two years without being able to photosynthesize - you'd think lots of species wouldn't have viable seeds kicking around at that point. Which would make for some massive changes to the fossil record for plants. To say nothing of the animals that depend on them...
- retSava 9y ago66 mn years is plenty of time to diversify a lot from a few, so you might be correct that "lots of species wouldn't have viable seeds". Perhaps they didn't, and just the (relative) few that did are the basis of what we have today.
- colordrops 9y agoLots of seeds remain viable for more than 2 years.
- QAPereo 9y agoIt would also have to remain viable in the sense that no animals starving in the darkness will try to eatthem, or fungus or bacteria running wild. I think you have to assume that are small burrowing ancestors ate pretty much every seed they could get their tiny paws on. We know that quite a few different organisms survived, and while some of them estivated or hibernated most of them presumably we had to live and eat in a roughly normal way.
- colordrops 9y agoSure but there's no way they'd find every single seed on earth.
- rangibaby 9y agoFungi and bacteria don't like the cold. There would be a lot more food to eat for survivors (chickens) as things that they competed with for food (T rex) died off.
