Episode notes
Evolution by natural selection is not perfect, nor does it strive to be. It doesn't strive to be anything at all. An adaptation that is beneficial under one set of circumstances may be a detriment under another. There are also some wonderful by products - like reading and writing. Did we evolve to read and write? Once again, imperfection reigns. Evolution Talk is also a book!

About Those Fingerprints
When it comes to personal IDs, we have many. There's your driver's license, passport, online username, among other human-made forms of proving who you are. Then there are those that nature gave you that's yours and yours alone. Like your DNA. And then there are your fingerprints. Other than leaving incriminating evidence behind if you've committed a crime and weren't careful enough to wipe them away or wear gloves, what are fingerprints good for?
