It's also comical the way people use *mean* annual temperature when making claims about evolution during harsh 'cold winters'. It gets below freezing during winter in the Kalahari but has a high mean avg. temperature. Just such a mess
People have used more than just the means, don't be silly (ranges, winter/summer etc.). The problem is that we don't have enough datapoints to try complex regression models, so people stick with the single most predictive variable, which IIRC is the mean winter temperature.
We don't have enough datapoints, and the datapoints aren't independent either, which also can be problematic
Sure, but it's a promising theory. It's probably one of the best in town. I think skepticism is good. But I also think it is a powerful and exciting theory that potentially explains a wide array of data.
