In biology and genetic genealogy, the most recent common ancestor (MRCA), also known as the last common ancestor (LCA) or concestor, of a set of organisms is the most recent individual from which all the organisms of the set are descended.
The possibility is mentioned, above, that all living organisms may be descended from an original single-celled organism with a DNA genome, and that this implies a single origin for life. Although such a universal common ancestor may have existed, such a complex entity is unlikely to have arisen spontaneously from non-life and thus a cell with a DNA genome cannot reasonably be regarded as the “origin” of life.

Edit: I didn't read close enough, you're right, it is individual.

It's a species, not a single individual.

Reply to comment by TheColorWolf in TIL that the dogs in competitive agility don’t rehearse the course ahead of time. The courses are randomized at each competition, and the trainers (without their dogs) only see the layout beforehand on the same day. When the dog runs the course they are literally seeing it for the first time. by Pyraunus
