In an article on various ways that life forms thrive in the dark, Brian Handwerk notes, re echolocation in bats:
scientists have recently learned that echolocation also plays an important role in bat social life. The calls bats use contain information including sex, age or even individual identity.
Using behavior experiments Jenna Kohles and colleagues recently demonstrated that some bats can even use this identity information while they’re flying and searching for prey.
“They can tell their group members apart from one another using just the “individual signatures” contained in the echolocation calls they use to search for insects,” says Kohles, a behavioral ecologist at the Max Planck Institute of Animal Behavior. “So the social lives of bats flying around at night are likely to be much more complex than previously thought.”

This raises an issue: Social intelligence seems to imply an underlying intelligence in the universe. It’s not at all clear that it is merely a matter of natural selection acting on random mutations (Darwinism).
For one thing, if there were no intelligence, there would be no need for social intelligence. Social intelligence is a response to existing intelligence. And no one knows how it arose.
That is why, wisely or other, the science world has been drifting toward panpsychism.
You may also wish to read: Why panpsychism is starting to push out naturalism. A key goal of naturalism/materialism has been to explain human consciousness away as “nothing but a pack of neurons.” That can’t work. Panpsychism is not dualism. By including consciousness — including human consciousness — as a bedrock fact of nature, it avoids naturalism’s dead end.
