Wow.
I think I have one more minute to read a poem.
And on a light note.
This is "Cope's Rule."
According to Edward Drinker Cope,
19th-century paleontologist, fossil records
show lineages become larger over millennia, indicating
that bigger is more successful.
Though later scientists offered further support
for Cope's rule, from mammals to corals,
paleontologists in the last century
challenged such evidence.
Gould, in particular, was dismissive of such
a psychological artifact.
Current, more rigorous studies suggest
the results are plain to see.
Being big provides a big advantage.
And yet, the study continues, why isn't
Cope's rule more of a rule?
Laws of physics reveal that insects cannot grow to the size
of Tyrannosaurus Rex because their exoskeleton cannot
support heavy loads of body mass.
Furthermore, a small rat is probably better adapted
to a certain niche.
There is also the issue of surviving mass extinction.
Though, not everything can get small enough quick enough.
I am small already, so that isn't a personal concern.
Still, each consecutive husband has gotten larger.
Though, I'm not sure why or what that reveals.
Except, it's easier for Harold to reach for stuff
on the top shelf rather than watch me
climb on the kitchen counter.
Though, last weekend, he bought, for us both, a step ladder,
ruling out vulgar advantage.
Thank you very much.
