The video explains the historical and scientific basis for classifying trees as hardwoods and softwoods. Initially, these terms were based on the difficulty of cutting the wood, but they later aligned with genetic classifications: angiosperms (hardwoods) and gymnosperms (softwoods). Despite the names, hardwoods are not always harder than softwoods. The video discusses the evolution, cellular structure, and diversity of both types, highlighting the Janka Hardness Scale as a measure of wood hardness.
