When discussing the аncestrаl humаn mating system, we cоnsidered hоw testes size can be influenced by the mating system оf the species. During this discussion we also analyzed the graph above. For each statement related to our discussion of testes size and this graph, select whether it is true or false. 1) Promiscuous species have large testes relative to their body weight because males compete with one another through physical fights, which require large testes. [1] 2) Polygynous species have large testes relative to their body weight because males compete with one another through sperm competition. [2] 3) The data suggest that the ancestral human mating system was polygyny. [3] 4) A possible benefit of large testes is that males produce more sperm and it is therefore more likely that a female will become pregnant with offspring of males with large testes. [4]
