Final answer:
Competing aggressively for mates is characteristic of certain animal mating systems, especially evident in polygynous and polyandrous patterns. Animals, such as male lions, can show fierce competition for mating rights. However, some species employ cooperative strategies for mating success.
Step-by-step explanation:
Competing aggressively for access to mates is an attribute typically observed in various animal mating systems, such as polygynous and polyandrous mating. In polygynous mating systems, multiple males may be attracted to a few females with rich territories, as females establish their own territories apart from others. By contrast, in polyandrous systems, a few males may be attracted to many females in each territory. Such competitive behavior, which can include courtship displays and territorial defenses, arises from the inherent need to pass on one's genes to the next generation.
Male lions, for instance, exemplify this competitive nature as they compete aggressively for the right to mate with females. However, in some primate species, social strategies such as friendliness and cooperation can also play a significant role in reproductive success. Nevertheless, for both males and females in the animal kingdom, the ultimate goal is to secure the best possible chances for survival and reproduction.
