Artificial selection of domestic animals, pets, etc. is one type of
biological evolution that overlaps a good deal with technological

Conversely, some technological evolution is more similar to biological
evolution, e.g. the use of in vitro selection of enzymes to look for a
useful product or the emergence of complex systems out of individual
interactions, without overall guidance (e.g., the economy, the

It's probably best to specify that there is no inherent direction in
biological evolution. Whether it is a part of providence is not
scientifically accessible.

It might also be good to emphasize that natural selection is not the
only non-random factor involved.

Not certain what this is. There are some odd patterns of selctive
pressure that occur in organisms that reproduce asexually in some
