Embryo

Material used: Coarse grain Sandstone found near Púbol, Catalonia.

Biology has always been obsessed by the process of ontology (development). This young near-term human embryo sprang from the unlikely union of two unrelated parental cells in just nine months, a phenomenal feat of bioengineering and logistics. To get to this point, the embryo had to undergo a tortuous series of metamorphic transformations which only make sense in the light of evolution; all creatures have hybrid lineages where diverse phenotypes were randomly bolted together, full of errors, spandels, and redundancies. And some lineages even survived this extreme experimentation. 99% did not survive.
