Were there thorns and thistles before the Fall of Adam?

[TonyChanYT]

ESV, Gen 3:

17 And to Adam he said, “Because you have listened to the voice of your wife and have eaten of the tree of which I commanded you, ‘You shall not eat of it,’ cursed is the ground because of you; in pain you shall eat of it all the days of your life; 18 thorns and thistles it shall bring forth for you;

Were there thorns and thistles before the fall of Adam?

Probably not. Before the Fall, nature was in harmony. There were species that were the progenitors of thorns and thistles. When God cursed the ground, these species mutated to produce thorns and thistles to protect themselves against some animals. This signifies the beginning of the struggle between plant and animal life.
