my favorite pet theory about the predominance of gigantism in fossils is that the earth had much higher barometric pressure in the distant past. Higher pressure allows cells to grow larger since they can be oxygenated better.

So aminals had the same DNA, same number of cells, just each cell was larger.

This changed after earth’s pressure was reduced by meteor strike and/or global flood calamity.

What would account for the giant anal orifices permeating the Obama administration? lol

While the story was interesting, I confess that I was more interested by the little box at the bottom, offering a choice of citation formats.... My kids are to the point now where they’re writing papers that require references, and the article offered a couple of alternatives (APA and MLS). Pretty nifty little gadget!

The problem with that theory is that the largest living organisms that have ever been discovered are still alive today; Blue whales.

So apparently, higher barometric pressure is not necessary for large size.
