The point is that if you’re seeing an individual do something novel, it’s not evolution. Evolution would be if it had a mutation that it passed on that made its survival more or less likely or in speciation - the diverging of one species into two or more. To be pedantic, it is in no way observable evolution. Scientists have observed speciation before when populations of fish got trapped in separate environments and became mutually sexually incompatible - so different species. That’s observable evolution.
