Answer:
The connection that the author draws is that babies learn social behaviors by observing others. So if parents understand this way of learning, they could foster a kid consciously and positively with their daily actions and interactions with the baby and others.
Step-by-step explanation:
The author states that babies learn from watching others, so regarding if being altruist is a genetic thing or not, we can shape our kids to be kind and fair by our daily actions. We can see it when the author says, "... the research suggests that, whatever the motive, infants have an early sense of both traits, which are preverbal. They appear to develop their social behaviors just by watching others, which the authors suggest could help adults understand more about how to foster that development in kids from a young age."
