Where did angiosperms evolve from?

The term comes from the Greek words angelion (« vessel, vessel ») and sperm (« seed »).ancestors of flowering plants from common ancestor of all extant gymnosperms In the Carboniferous period, more than 300 million years ago, the earliest records of angiosperm pollen appeared 134 million years ago.

What evolved from gymnosperms?

Why did angiosperms replace gymnosperms?

The competitive success of angiosperms is partly due to animal pollination, which allows angiosperms to exist as discrete small populations. Wind-pollinated gymnosperms require large contiguous populations for efficient pollination.

Why are gymnosperms so successful?
