jd spoonworthy defined it nicely. enable me purely upload: How does evolution make different horns completely symmetrical? extraordinarily plenty all animals you be responsive to are bilaterally symmetrical, the two sides of the physique seem the comparable. A mutation that has effects on my thumb will frequently influence the two my thumbs. A mutation that makes my ears bigger will frequently make the two ears bigger. So maximum possibly, the comparable gene is responsible for the two horns. How does evolution "be responsive to" what to do: You confuse this too plenty with Lamarckian evolution. it rather is unlike evolution says: "hiya, a horn could be advantageous" and then a horn grows. the recent good factors seem via twist of fate, via mutation, and then finally end up to furnish an benefit, so as that they are saved interior the species. purely like a ball does not "be responsive to" which direction is down so it could fall that way. Now, needless to say a horn is slightly complicated, it does not purely seem suddenly. It ought to have began off as a small exchange, like in line with risk a bump, which offered some benefit, and then that bump transforming into bigger offered yet another benefit, etc. Now i do no longer be responsive to the way the horn rather progressed, yet spoonworthy offered a robust clarification. (nicely I examine in Wikipedia that for the duration of between the Rhino's ancestors, Menoceras, the adult males purely had 2 horns section via section on their nostril. later on, it form of feels, those horns ended up in the back of one yet another.)

It's made of the same thing as our hair and fingernails.
It's made of highly compressed keratin (a protein) which is also what develops our hair and fingernails. Pretty interesting.
