1. There is active selection. The environment selects.
2. The concept of "purpose" is misdirected. We think of purpose as something
possessed by intelligent beings. Ditto for "intent". In both cases it means that
the future is somewhat controllable since both purpose and intent imply an
occurrence sometime later that we "want". But nobody succeeds 100% of
the time when things are complex. For example, children rarely turn out
to be exactly what their parents intended and yet parents really intend
for their children to possess some characteristics.
3. The fossil record shows that the animals that show up later have larger brains.
Putting all together it seems to me that a Markov process may be said
to be "intended" since there is some predictability. The only thing missing
seems to be the "intender". But the intender is the environment and nowadays
we are a part of the environment so it is very complex.
PS. Some readers will have problems with #2, but even there the concept of
"intent" (as the lay person understands it) is something that may be thought
of as akin to that of environment. After all, what if the "intent" which is a
product of the mind/brain is something as uncontrollable as the environment.
In other words, if the brain/mind is a machine then it works just like the
environment (e.g. an impersonal and complex interaction of millions of
entities). In other words, they are both "machines" mostly out of control
of us! So do we really have "free will"? No wonder the problem is really
difficult to understand.
