Which of the following plants has the longest evolutionary history on land?

A) ferns
B) bristlecone pine tree
C) moss
D) redwood tree
E) grass

Mosses are some of the earliest terrestrial organisms, with an estimated evolutionary history of at least 400 million years. While ferns and other plants also have a long history on land, mosses are believed to have colonized land earlier than most other plant groups. Bristlecone pine trees are some of the oldest living organisms on Earth, but they are not the oldest land plants. Redwood trees and grasses are relatively young in terms of evolutionary history on land.
