what are the mathematics of evolution?

(HINT: If a subject doesn't have mathematics to back it up, it's not a science)

Its largly genetics and statistical analysis of mating behaviour. Its actually very complex research.

...
I dispute that point actually. Science is about studying the world around you. For example biology stems from the word Bios = life and logos = study of.
Logic seems to be more about studying the relationships between things.
Maths seems to be about quantifying things and arranging and representing information. Thats why its not called mathsology.

Nice! You don't happen to have access to the missing chapters do you? I'd be quite interested to learn a bit about this but I don't want to fork out for textbooks considering I don't have any biological education, but any mathematics is always a joy to learn about, and I could use some knowledge about evolution.

Ah well, thanks anyway, saved those for later. The beautiful thing about studying mathematics is how broad the range of topics it prepares you to engage with is, so I'm always thrilled to learn about new areas.

kind of, but not really

Mathematics talks about the relationships between mathematical entities. Though they don't actually refer to the real world by purpose, more as a coincidence because the real world can sometimes be thought of as an approximation of the perfect mathematics.

Consider a triangle. Any triangle will do. Now, zoom in one one of the corners, do it again some more. Does this triangle ever become less sharp? Is there any atomic scale? no. These things do not apply to the mathematical universe, you can zoom in infinitely and the angle will remain unchanged and the figure won't break down into discrete units (quanta in the physical universe). Now zoom back out so you can see your whole triangle again, as when we started. Consider it's area. One way to deduce it is by doing some geometric operations on it, namely by cutting the triangle in half from the topmost angle (remember, we have on side facing down) and then rearranging the two halfs of a triangle so that they make a box.

This box will have a length of half the triangle's bottom leg, and a height that's the distance from the top angle to the bottom angle (perpendicular to the bottom angle). In other words

Area = (H)(L/2) = (H)(L)/2

If this were the real world we'd only be able to make this measurement approximately. In the mathematical world we know that it is exactly that, no more and no less.

Astrology stems from the word Astro = stars and logos = study of. Astrology is science.
