At the age of fifteen I wrote my first book, with no intention of publishing, just for my personal use. It was a two-volume zoology of invertebrates. I still refer to it, although classifications have changed a lot, with the rise of cladistics and DNA analysis.
In 1977, this time with the intention of
sending it to the printer, I wrote another book in English under the title Human cultures and evolution, where I proposed
the following:
· Cultural evolution is equivalent to biological evolution. Many properties are common to both fields. Human civilizations are equivalent to biological species and describe similar life curves. There is a cultural selection, equivalent to and very similar to natural selection, proposed by Darwin to explain the origin of the species.
