I don't think the Bible says plants and animals are created in the same manner.
Take a closer look to the verses describing the creation.
Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds. And it was so.
God said, Let the water teem with living creatures, and let birds fly above the earth across the vault of the sky.
So God created the great creatures of the sea and every living thing with which the water teems and that moves about in it, according to their kinds, and every winged bird according to its kind. And God saw that it was good.
God said, Let the land produce living creatures according to their kinds: the livestock, the creatures that move along the ground, and the wild animals, each according to its kind. And it was so.
God made the wild animals according to their kinds, the livestock according to their kinds, and all the creatures that move along the ground according to their kinds. And God saw that it was good.
We don't read God created various grass, herbs or trees according its kind as He did with the animals. We read only that God said, "Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds. And it was so.
No one of us know how was the process, why should we argue, there never occurred any evolution?
May be God's plan for the vegetation to evolve into species, who knows. But with creatures in the sea and creatures on the land we read, God created the great creatures of the sea ...according to their kinds, so is with birds and animals on land.
The creation man is even different. He created man in His own image.
We can only marvel at the very truth that all that is created is inferior to man and God has a definite plan for the creation. Praise the Lord!
