Answer:
a. sexual dimorphism was developing over time in these species.
Explanation:
Sexual dimorphism refers to the presence of observable distinct phenotypic differences between the males and females of the same species. In humans, adult males have a larger larynx which is responsible for their deep voice than females. Females have a relatively smaller larynx. Therefore, a trend toward decreasing larynx size in adult females and increasing larynx size in adult males in fossils represents the development of sexual dimorphism in these species.
