What people are saying
The collection includes comments emphasizing the importance of evolutionary understanding, such as recognizing the study’s role in clarifying vertebrate evolution, alongside dismissive remarks and unsure responses, illustrating a mix of recognition and uncertainty. The tone varies from academic to casual, and the focus ranges from biological implications to mere social discussions, leading to a neutral overall evaluation.
The comments show mixed reactions, with some recognizing the importance of the study and others dismissing or questioning its relevance, leading to a neutral overall agreement.
Discussions display varied levels of interest; some focus on the evolutionary significance, while others express uncertainty or minimal engagement.
Participants show superficial engagement, with some posts only sharing vague or peripheral comments without deep analysis.
The overall impact appears limited, as the posts reflect curiosity or skepticism rather than widespread enthusiasm or significant influence on broader scientific conversations.
Abstract in brief
- The study investigates the evolution of the phallus in amniotes by examining tuatara embryos, which lack an adult phallus, to understand if external genitalia have a common origin.
- Researchers reconstructed three-dimensional images of tuatara embryos and found that they develop initial stages of external genitalia (genital anlagen), indicating a conserved developmental process across amniotes.
- These findings suggest that despite differences in adult external genitalia, amniotes likely share a single evolutionary origin for their external genitalia, rather than multiple independent evolutions.]

Evolution of External Genitalia in Amniotes Based on Tuatara Embryos
This video explores why many birds lack penises, highlighting that internal fertilization does not require a penis. It discusses natural and sexual selection, and the evolutionary development of external genitalia based…
