Luna moths are well known among large American silkworm moths & the twist drill bit was invented by Steven Morse of Massachusetts in 1861. One evolved into a significant manufacturing process for the industrial revolution & the other hasn't changed since the 6th day of creation. Photoshop evolved as part of the digital revolution & enables images (like this one) to be done with keyboards & electricity.
