Which term describes the factors that draw members of a species together?

The term that best describes the factors that draw members of a species together is attraction. Attraction can refer to a variety of social and biological mechanisms, including physical attraction, emotional affinity, and social bonding, which ultimately promote cohesion and cooperative behaviors within a species. These mechanisms play a crucial role in reproduction, social structure, and the formation of groups or communities.

In contrast, aggression refers to behaviors that can lead to conflict or competition among individuals, which is generally oppositional to the concept of drawing members together. Attachment typically involves the emotional bonds that can form between individuals, often based on past experiences and interactions, rather than a general attraction factor. Altruism describes behaviors that benefit others, often at a cost to oneself, but does not directly address the factors that bring individuals together. Thus, attraction is the term that most accurately encapsulates the concept of what draws members of a species to one another.
