  • As a joking afterthought at the end of your last video

  • you asked me what came first

  • the chicken

  • or the egg?

  • and the answer is much simpler than most people think

  • and also far more complicated

  • the answer is the egg

  • the egg that would have hatched the very first chicken

  • would have been laid by a creature that was very, very similar to a chicken

  • but not quite

  • the more difficult question is what is a chicken?

  • At what point would a creature that was very much like a chicken

  • but not quite

  • tip over into being an actual chicken?

  • It wasn't until I was out of University that I had any understanding

  • of the theory of evolution

  • through reading articles and watching youtube videos

  • and while I don't claim to have an amazing amount of knowledge

  • please allow me to butcher some very basic evolution for you here

  • the distinction between what is a chicken

  • and what is almost, but not quite a chicken

  • is decided by humans

  • we like grouping things

  • this is this

  • that is that

  • these are the ways that they are similar

  • and these are the ways <garbled> different

  • we see the progress of evolution through periodic markers of change

  • the most famous image image relating to evolution is called 'The March of Progress'

  • its the one that looks like this

  • it was created by an artist called Rudolph Zallinger

  • that's not particularly important to what I have to say today

  • but 'Rudolph Zallinger' or 'The March of Progress'

  • is bound to be the answer to a trivia question one Christmas

  • and when that question is asked we'll look at each other and go

  • "aaah"

  • but we view progress as this becomes

  • <chwnk>

  • this

  • which in turn

  • <chwnk>

  • morphs into this

  • like a pokemon turning level 16

  • the metamorphosis occurs

  • this one isn't a chicken

  • this one is

  • that isn't how this works

  • in the many millions of years it takes for this version

  • to become this version

  • so many millions exist in the middle

  • this isn't mk. I -> mk. II

  • in reality there were innumerable different forms between the two

  • it was less a progress of incremental forms and more like

  • a Hollywood-LSD mesh of 'bleeeeurgh'

  • morphing onwards through millions and millions of years

  • and that's fun

  • bleeeeeurgh

  • so why do we decide that this one is not a chicken

  • and that this one is

  • I don't know the details

  • I'm not a scientist

  • and anyway

  • neither of them are chickens

  • they're my hands

  • <buk buk buk buk>

  • I'm just a bit disappointed that I didn't get more of an evolutionary

  • education at school

  • although to be fair a lot of that responsibility may lay with my class

  • it might be our fault

  • one time we were in a biology classroom

  • and we were meant to be learning about osmosis

  • now to do this we had potatoes and we were meant to be

  • taking samples from them to see how water passed through them

  • and instead of doing this

  • we threw them across the room at each other

  • we were the top set of triple science

  • we were 28 years old

  • and we were also the teachers

  • and the potato was my mother-in-law

  • Anyway now you know that the egg came first

  • maybe that's why the chicken crossed the road

  • Ffarwel!

  • <buk buk buk buk>
