Couldn't it be said that animals build structures based on what works with no understanding of why it works??
No question that a termite does not understand why that structure works, and i can easely see the structure part of the evolution of those termites.
- the termites that dug their "city" died more often then those that built it upwards
- the termites that made flat cities facing the right way died less often then those that built it differently
- the termites that made holes at the bottom and top to alowe for hot air to escape up top thus sucking cool air from the bootom died less then the termites that had no holes or holes at the wrong places
just a few millenia of trial and error and success encoded in their DNA.
tough still their structures are designed, the only diference is that their trials and errors are "writen down" <-- .....
