Two brief videos that sum up, in very different ways, our story. The first – just 2 minutes long – was made by a high school student call Joe Bush and was first posted on YouTube back in May. It has been seen by over 6 million times, but I only just noticed in on UK journalist John Snow’s Twitter feed. See what you think:
The second video is even older, and is one I show to my students every year. Joe’s video is not to scale – understandably, there’s a massive amount of time devoted to the last 100 years. This video, by Claire Evans, shows the evolution of life on Earth in 60 seconds, but told proportionately. Much of that minute, as you will see, is thus devoted to unicellular organisms just sitting there and doing there thing. The real action begins in the last 9five seconds, after the Cambrian Explosion (sorry for the spoiler). And of course, at this time-scale, human history just isn’t visible.
PS. I’m sure I’ve posted this before on WEIT, but can’t find it on the site. And it should be ‘last banded iron (not ion) formations’. A corrected version was posted by Claire, but I can’t find it anywhere.
PPP. The reason for the hashtag in the title is because in the UK, tonight is the second episode of Wonders of Life with Brian Cox on BBC2, and I thought we might pick up some extra readers!
