It seems to be almost a joke of Nature, or an easter egg by the programmers, that we big things evolve into small things over millions of years.

Have modern day Humans broken that cycle in that we consume so much resources that we do not allow other big things to evolve and grow. Or is it just entropy as the planet ages? Or just that we cannot see things on the timescales of hundreds of millions of years? Will there one day be other giant creatures swimming the oceans or wandering the Earth?

I would say once size becomes a liability then things get naturally get smaller.

We notice big things, then kill and eat them.

We have overcome "size" as a defensive measure in nature, it is redundant as a strategy.

It’s natural selection if bag heads has an example stay in there house that’s fine or away from nasty people you end up with lots of bag heads .they take over the locality if they get targeted by people higher up the food chain they migrate to safer climates .it’s the circle of life .

Your argument seems to suggest that we have supported that cycle?

We've probably acted to make species evolve to be sneakier and more nocturnal (or "shier" as Attenborough would say). And with a finely tuned nose for human presence. Hence all these rumours of extinctions..which then prove false as anti-human adaptations are slowly eroded.

Take N Sea Cod as an example, but repeated in many fisheries

Typically, cod reach sexual maturity between 3-5 years of age and live for 25.

Only smaller fish escape the net

Consequently, there has been selection towards a small size at sexual maturity - early maturation is favoured. Only those that escape through the mesh of the net get to breed. A genetic constitution that enables early maturity is therefore favoured.

(This also has a knock on effect upon abundance because small fish lay less eggs.)

 

Here's an article referring to a similar effect but in a different fishery to the N Sea

ORIGINAL ARTICLE: Size‐selective fishing gear and life history evolution in the Northeast Arctic cod

I don’t think so. The blue whale is the largest animal that has ever lived.

 

Although they could find evidence for the “Pangean Titan Ant” tomorrow.

What's the film called? Downsizing


Humans are evolving though.
