Now once again, I am not sure if I agree or not.

ok, i see what you are saying, however, the "instinct for survival" is really just pop-science.
Yes, animals act for personal survival, but simply because it ensures that their genes will be passed on to the next generation.
Given that humans are highly social creatures, and would have evolved in band like family groups, it is likely that a large percentage of your genes are shared by those who are close to you.
Now, its not like the early humans were making charts of who had more of their genes, but, lets say there are 2 groups.
Group A and B are similar in some ways. They are each a family group, and all members have genes very similar to those also in the group.
The genes possessed by group A, lets say, prevent them, because of survival instincts, from jumping into a river to save another person. Now, the genes of group B say that they should jump in to rescue them. Which group is going to pass its genes on better? Most psychologists (especially those who do work with evolution) feel that group B would, as the self sacrifice keeps more of the same genes around to be passed on. This could also explain why anyone would be much more likely to save a baby than a grown woman.
