Christmas tree genome relatively unchanged in 100 million years


Science can make better corn and, well, better everything – except perhaps the Christmas tree. The genome of conifers like spruce, pine and fir has remained pretty much the same for the last 100 million years – a remarkable feat of genomic stability.

This great stability goes hand in hand with the low speciation rate of conifers. The world is currently home to only 600 species of conifers, while there are over 400,000 species of flowering plants.
