Yes...it should be obvious that most of the traits in humans, especially globally widespread ones, should have their roots in the animal world. That should not be surprising.
But it does raise the issue of why some of these traits evolve.
The TofE provides the best explanation to date for how species and their characteristics evolve: there is no 'why', just 'how'.
Saying that it is for survival doesn't make sense because even those animals that do not display these traits survive.
Other species have less need for human traits than do humans, just as we humans have less need for wings or gills.
The usual, random genetic variation and Natural Selection 'explanation' also does not wash.
It washes fine.
So, why have religions developed so universally across the world. What do religions do?
They unite people,
Yet they have been, and still are, a key source of human conflict.
they enforce morality,
On their own terms to only those who accept the authority of religions as regards morality: many don't, and nor is morality the exclusive province of religions.
they lay down norms for society,
On their own terms to only those who accept the authority of religions as regards social norms: many don't and, moreover, since some aspects of religions can be viewed as being socially divisive then, for some of us, like me, religions have no personal relevance and is something that happens to some other people and it is only when the effects of religion on others intrude into wider society and social policy that I find religions are relevant - sadly though these effects tend to be negative rather than positive.
they give life a sense of purpose,
To some, but not all.
they give us solace and comfort...
To some, but not all.
and finally they also teach us some fundamental truths about our own consciousness and mind that we are usually unconscious of.
As far as I can see they don't say anything about psychology or neurology, so I suspect you are over-reaching again.
This clearly points to the fact that evolution has aided our self awareness and realization of the complexities inherent in our personality. This is what spirituality and Yoga teache. In other words, biological evolution has made spiritual development possible. They go hand in hand.
If 'spiritual development' is code for mental activity involving abstractions then it is just a form of biological activity that is a trait of our species.
Instead of seeing spirituality/religions as chance byproducts of evolution, we should see them as one of the goals of evolution.
The TofE doesn't involve goals: there is no intended purpose involved.
