An intriguing (if speculative) possibility is that sexual selection for greater age occurred among our hominin and human ancestors, favouring males who appeared older than they actually were.
A highly speculative but attractive idea is that secreted RNases can control the activity of small RNAs [ 48].
Another more speculative explanation would be that AQP11/12 in fact originated from an algal MIPC via HGT.
However, although speculative, one explanation could be that EPO influences gut hormones and their effect on insulin secretion.
