At the top of a small hill in suburban southern California, there is what appears to be a thicket of stunted, gnarled oak trees wedged between a pile of boulders. A passerby would likely miss this ancient, biological wonder.
The entire grove of trunks is in fact one plant, a newly discovered Palmer's oak (Quercus palmeri) that researchers estimate is over 13,000 years old, making it one of the oldest plants on Earth.
