![Screenshot from the article: "Importantly, evolutionary theory predicts that selection favours the evolution of exactly two, and not more than two, gametic strategies (Lehtonen and Parker 2014)—a prediction that is strongly supported across anisogamous species: with the [highlighted] exception [end highlight] of a few rare lineages showing slightly overlapping yet bimodal gamete-size distributions (e.g., in certain algae; Clifton and Clifton 1999), all anisogamous species ['all' is scored out] exhibit two distinct, non-overlapping size classes of gametes. Thus, despite independently replicated evolutionary origins, the emergence of anisogamy is associated with only two classes of gametes, and never more. It is precisely this highly consistent occurrence of two distinct gamete size classes across anisogamous species that renders the definition of biological sex based on gamete size inherently binary. However, defining biological sex as binary does not imply that individuals necessarily fall into two classes, as they can produce male, female, both, or neither gamete class."](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:l2vfym7umsdlf7aqfa7d7bji/bafkreiex7zus5x4q4bybnievlhb3pt7wfl6z6z7pymrnwxddyhhwuf5gqe)
