Sorry I've not posted in several days. The classes I'm teaching are new, so there's a lot to prepare each week. I've read all of the responses and shared them with my students last week. They appreciated the feedback. If it's alright, I'd like to post questions that the students may come up with or need clarification as we cover different topics. We are just seeking to comprehend.
The next question: (we now understand why we didn't evolve into 7 or 7000 "sexes") ... is at what point did we go from being asexual to being sexual (2 sexes) in order to reproduce?
