On a recent field trip, neither my students nor I was at threat of being eaten alive by a t-rex.
Why, despite ruling Earth for nearly 80 million years (even longer than Wall Street barons), are Cretaceous period animals not regularly chowing on our gizzards? Things change.
Scientists have suspected this for some time. In fact, a growing body of geologic evidence seems to support the theory that things today are not the same as they were 200 million years ago. (Many even suspect tomorrow will be different than today.)
Surprisingly, this idea of “change as constant” is not yet an accepted norm. (Though it comes as no surprise to anyone whose visited any number of schools in recent years.)
