An example might be theorizing on how spiders evolved web building. How is it possible to check that? It starts with the assumption that this evolved and that somehow the knowledge of it was able to be stored in the genes of the spider to be passed on to little baby spiders.
I hope this isn't just another God of the gaps
argument.
The hows and what's of evolution
Is very thoroughly dmonstructed in
some instances, in others, it's much
more difficult.
Does it mean the theory is correct
for this, but not for that?
There is no other explanation besides
evolution that has any explanatory value,
at all.
In the case of spiders, investigating
web evolution requires no assumptions
other than that there might be some
value in investigating.
The wonderful geometric web, would someone think there was a first spider who did that,
first try?
Do you know of any intermediate steps
that can be observed in living organism,
that would show that the evolution of
geometric web from simpler origins is
plausible and corresponds with the theory?
