why are we male and female?
Yeah, I researched this for my jw SIL too. Provided her with pages of good stuff about all the different forms af reproduction and she dismissed it all with "I expected you'd have some explanation" So if you do actually want to know do your own research. I suggest starting with unicellular life.

Walked and/or climbed just as flightless birds and hoatzin do today.
