1.) There are significant differences between single celled animals and us,
and every educated evolutionist would agree with me in that point.
a.) We (Homo sapiens) constitute a natural, monophyletic lineage to be placed
somewhere in Mammalia. Single celled animals, on the other hand, represent a
generalization which refer to the way the individual is organized, it is a
level of organization. Namely, single celled animals are those organisms which
have one cell only each and which do not do a lot of phototrophy
(otherwise they would be plants)
b.) the decisive differences between colonies of protozoans and humans are
many: for example humans can have cancer, virus diseases, and somatic and
sexual cells are separated.
All three of these characteristics cannot be found, to my knowledge,
in colonies of protozoans.

This is an interesting statement. It implies, to my view, that the true
taxonomist works naturally. What, however, is THIS NATURE made of?
I mean I just wrote some stuff by Popper about the philosophy of science, where
he opposes the Hegelian view (which states that every individual ultimately will
reaveal and express itself due to some strange inherent laws of nature in the
sense of some spiritual essence which tends to reveal and express itself) with
the view of critical rationalism (which states that there are simply some
problems in our universe which are solved by scientists because they receive
payment or get an opportunity to combine their problem solving capacity with
their needs to survive.)
OK, let's do the garden Thomas
