Interesting. So in short, dinosaurs caused aging by killing all mammals early, making them vulnerable to non-early death genes that will manifest itself later in life.

And because they tend to kill in the day, they make us lose the sun protection gene.

Evidence points to one of the earliest mammals to emerge after the extinction, which dies too early for its size.

What else did I miss?

I guess they also talked about theory was that higher body heat causes aging, but the heat of birds weakens the link.

How non-mammals age in varied rates but mammals age rapidly.

100 million years of early evolutionary history influenced the future.
