And we don't think the sizes of sperm or testes are influencing the phylogeny, but rather the reverse - that phylogeny is influencing testis structures and sperm size in anoles.

Thanks for checking it out! And not a dumb question. But, I don't think testes' structures could "define" a phylogeny as you suggest - they aren't directly involved in the evolution of isolation the way genital structures often can be.

Universities tend to be in blue cities and towns. Because when you learn about how wonderful and different the world is, it changes you. You have empathy. You have compassion. You understand other points of view and learn from world history.

It's so true!! And brilliant coauthors make the work more fun. 😊
