A recent editorial illustration for Harvard Magazine for a feature on evolution, and why it favours sexual reproduction over the asexual alternative. This was quite a nice one and the ideas came to me quite quickly. You can see a few of my rough concepts below as well as a few pages of my sketchbook where I put my initial thoughts down on paper.
I think I still prefer the the middle concept (beer bottle pouring a double helix into two separate glasses) but it was not to be. Hopefully, there will be a time when I can reuse the idea.
