Conifer genome constant for 100 million years

Oh tannenbaum! A study published by the Canadian Forest Service and researchers at Université Laval reveals that the genome of conifers like spruce, pine and fir has remained virtually unchanged over the last 100 million years. That means the Christmas tree in your living room right now is nearly identical to what existed during the Cretaceous period.

According to a report in Science Daily:

Researchers compared the genome macrostructure for 157 gene families present both in conifers and flowering plants. They observed that the genome of conifers has remained particularly stable for at least 100 million years, while that of flowering plants has undergone major changes in the same period.
