>>What did spiders catch in their webs before the fall?
Probably the same thing they catch now.
What do YOU think they caught; air-borne fruit and veggies? What did they use their sting for - to anesthetize fast moving asparagus?
Moving along,
How do you explain the female morphology of XY (male) human embryos?
From excrement to implied gender crossing. Interesting, for a conservative Christian.
There is no prenatal "female" morphology for male children in the womb. Mullerian ducts, Wolffian ducts, one develops, one wastes away due to genetic and hormonal influences. If you want to call a genital bud female because it's not a penis, you'll be mistaken.
