This work is quite timely being created almost 200 years to the day since Darwin was born - though ironically, it isn't actually about Darwin in a direct sense. It explores the differing perception of species between the Victorian world and today. In Darwin's time, nature was largely seen as being "given" by God. The various species and diversity of life having been created essentially for the service of man. Of course this is diametrically opposed to the modern scientific world in which everything has evolved essentially by accident.
To me the irony of this is that we are now beginning to design species of plant and animal using genetic engineering. The work isn't intended to portray this as a good or bad thing. Merely to reflect on the idea that in centuries to come an intelligently created - rather than naturally evolved - world may well come about.
