Would evolutionary timelines or cycles be slower in an overall colder planet?

(Thinking of those interactive diagrams for temperature on the kinetic energy of molecules zooming around in closed space)

Did you ever read Dragon's Egg?

It's a speculative hard sci-fi that posits ultra-fast evolution for life on the surface crust of a neutron star!

[loosetypes]

Interesting! Thanks. No I have not.

Although I was previously recommended Rocheworld by a former NASA researcher, with the note that Robert L. Forward made every effort to describe a scientifically plausible double planet.

Incidentally, it looks like Dragon’s Egg is his only work available on Audible. I’ll add it to my list.

TIL!

Oh, looks like this movie "Evolution" ( https://en.wikipedia.org/wiki/Evolution_(2001_film) ) was also on those lines then!

It's an interesting idea, but I find characters developed on the surface of a neutron star will end up being implausibly flat, lacking any depth.

I see what you did there...

Also, the book does describe a character's apprehension at climbing to the dizzying heights of a few millimeters off the surface.

Somehow I don't think they are going to invade other planets anytime soon.

Well, at least that seems to be the case on earth. Creatures from the cold deep sea have slower life cycles than creatures in the tropics.

Shorter life cycle sounds like faster evolution actually.
