@Olivier5,
Still didn’t Need meat tho huh?😎
Keep in mind it was the GARDEN of Eden, and that before the flood the earth was much more lush with plant life, probably a lot more variation too.
This is why animals after the flood, when food sources were diminishing, began to resort to flesh.
Also keep in mind because things are ‘DE-evolving’ if anything, specialized diets are probably more common now in life forms than their much more Hardy ancestors.
At the end of the day, if the intelligent designer wanted the lion to live on no food at all, what would be the problem?
