Red Pine is an evergreen tree characterized by tall, straight growth in a variety of habitats. It usually ranges from 20–35 m (65-115 ft) in height and 1 m (3 ft) in trunk diameter, exceptionally reaching 43 m (141 ft) tall (Gymnosperm Database). The crown is conical, becoming a narrow rounded dome with age. The bark

 is thick and gray-brown at the base of the tree, but thin, flaky and bright orange-red in the upper crown; the tree's name derives from this distinctive character. Some red color may be seen in the fissures of the bark. Red Pine is self pruning; there tend not to be dead branches on the trees, and older trees may have very long lengths of branchless trunk below the canopy.

The species is notable for its very constant morphology and low genetic variation throughout its range, suggesting it has been through a near extinction in its recent evolution
Evolution
Evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organisation, including species, individual organisms and molecules such as DNA and proteins.Life on Earth...
