The way I like to look at evolution as it simply builds upon existing features, is like if instead of getting an entirely new operating system for computers, you simply patch the very first and original one.

@am1089 Every "patch" in this analogy is a new mutation that becomes an adaptation to an organism's environment.

@am1089 I could be wrong with my analogy, as I am definitely not an expert, but the patching has been going on since the dawn of life, and this process is still happening, albeit quite slowly. Will it stop one day? Not likely, barring the complete annihilation of life on Earth, and assuming we never figure out a way to make other planets or moons our new homes before the Earth gets obliterated by our sun as it swells into a red giant.

@am1089 Well, it's been uninterrupted so far.
