Botany Photo of the Day and the Oldest Living Organism
The oldest known organism on the planet is about 4,800 years old. Find out what that has to do with the Botany Photo of the Day.
It is often very hard to tell the difference between various species of pine. One of the distinguishing characteristics of this species (left) is that it has five needles per cluster. Other species have one, two, or three. I don't know if there is a species with four needles per cluster, or six.
Here's a question for all the adaptationists, is number of needles per fascicle an adaptation or is it just an allele that was fixed by accident? Is it an example of a morphological characteristic that is not an adaptaion?
