It has been postulated over the years as opposed to the picture drawn from the minds of men of an apple from Eve to Adam, that the actual fruit of the Tree of the Knowledge of Good and Evil was a fig. So here in chapter 3, verse 7 we see another very significant hint as to what happened from taking of the Tree of the Knowledge of Good and Evil. Verse 7 tells us the eyes of both of them were opened, and they knew they were naked; so they sewed fig leaves together and made themselves coverings.
The first thing that man did after the sin of taking of the Tree of the Knowledge of Good and Evil, disobeying the truth of God's Word, was to see their physical differences not from God's perspective toward unity but in the perversion of disobedience and the mind of men towards division. Then taking the leaves from that very tree, they determined for themselves to protect their own different parts that God had made to perfectly unite them physically.
