By-products of Evolution - why not everything has a purpose

Last time we looked at how certain major adaptations such as hair loss have enabled humans to survive over the millennia in different conditions, and when faced with competition from other species. Not everything about the human body has a specific purpose, though, in the sense that we expect it to. One example of such thing is the philtrum - that little channel leading from the base of your nose to the upper lip. Recent research suggests that this development dates back millions of years, and has been inherited from fish. Apparently, when human embryos develop their face in the womb, all parts of the forehead, mouth, etc come together and fuse where the philtrum is located. Some adaptations, on the other hand, are no longer relevant not because of their nature, but because the environmental selection pressure for which they evolved has disappeared. For example, an East Asian's typical eyelid shape evolved as a result of higher light intensities in that area of the world, yet th...

4 Reasons Google's Calico Won't "Solve Death"

The on-line world has been taken ablaze by Calico's bid to end ageing, and thus death itself, but is this what they will actually focus on, and will they achieve it? The fact is ageing will be reversed, and death by "natural causes" will go with it. The questions are "When?" and "By whom?". Until recently, not a lot was known about the approach Calico would take in this venture dubbed "moonshot thinking" - a term touted by Google as the source of all considerable human progress throughout history. This we don't doubt, but is this what Calico is all about? CNN's Dan Primack has revealed details about Calico's plan , which hint at a less-than-moonshot thinking approach, and cast a serious question mark on its ability to deliver the punchy TIME headline. Here is why: 1. The man with the idea, Bill Maris, arrived at the conclusion that the root of all death-causing disease is simply ageing itself. Not only is this widely ...

The "Purpose" of the Female Orgasm

I read on Wikipedia today that the female orgasm has no reproductive use, whereas the male orgasm does. Who the hell comes up with this bollo**s? Firstly, orgasms by themselves cannot be directly related to reproduction, since the vast, vast, vast majority of living things reproduce just fine without them. Secondly, there is no such thing as purpose in evolution. Our idea of purpose is something preconceived to serve a function. For example, a chair is made to be sat on. A typewriter is made to be typed with. A blog post is written to be read and shared. Evolution does not work that way. Nothing is ever made to serve any function because nothing is made according to a function, before that function exists. The concept of function itself is tightly dependent on the environment. A function is the relationship between two things which are connected to each other by cause, effect and time. The only reason most things have a function in living things is because those that did...
