Final answer:
The most documented species for infanticide behavior is the lion (Panthera Leo), known for males killing offspring to pass on their genes. The reference provided is about historical human behavior and not biological infanticide in species.
Step-by-step explanation:
The question pertains to which species is known for infanticide, and specifically, which species is the most documented for this behavior. The topic of infanticide in the animal kingdom is broad and can be found in various species, including some primates, lions, and other mammals.
However, among the most documented for engaging in infanticide are lions (Panthera Leo), where males may kill the offspring of other males to bring the females back into estrus more quickly and thus pass on their own genes.
The reference provided, 'Did the Jews Practice Infant Exposure and Infanticide in Antiquity?', discusses the historical perspective of human behavior and is not directly related to the biological aspect of infanticide in species. Therefore, in terms of biology, we should focus on the studies that document such behaviors in the animal kingdom.
