Comparative Xenobiology

Comparative xenobiological chart

Exobiology (also called astrobiology or xenobiology) was the biological science concerned with living alien organisms. Exobiology was also taught at Starfleet Academy. A biologist who specialized in the field of exobiology was referred to as an exobiologist, xenobiologist, or astrobiologist.

The Boy Scouts awarded a merit badge for exobiology in the 22nd century. Malcolm Reed had earned this badge by 2151, while Jonathan Archer had not. (ENT: "Rogue Planet")

Still, Archer had received exobiology training prior to his captaincy of Enterprise NX-01 in 2151, so he knew statistically only one of 43,000 planets supported intelligent life. (ENT: "Fight or Flight")

According to a beginning course on the subject, Exobiology 101, it was taught that "Humans are carbon-based. Our immune system can't fight silicon." (ENT: "Observer Effect")

In 2154, Doctor Phlox was offered a position on at the IME as Director of Xenobiology, a position he ultimately turned down in order to stay aboard Enteprrise. (ENT: "Affliction")

During the USS Enterprise's visit to planet Arret in 2268, Doctor Ann Mulhall from the ship's Astrobiology department was "summoned" to join the landing party. Planet-side, Mulhall's role on the mission included, but was not limited to, taking tricorder readings of the underground complex' atmosphere and composition of the alloys used in its construction, as well as observing James T. Kirk's reaction of euphoria, when his body became inhabited by Sargon. She later gave her professional opinion on the origins of mankind on Earth, explaining "Our beliefs and our studies indicate that life on our planet, Earth, evolved independently." Later, Mulhall was willing to offer herself as a receptacle for Thalassa, justifying the opportunity with stating, "I'm a scientist. The opportunity is an extraordinary one for experimentation, observation." (TOS: "Return to Tomorrow")

Data graduated from Starfleet Academy with honors in exobiology in 2345. (TNG: "Encounter at Farpoint", "Shades of Gray", "Tin Man")

Prior to becoming joined with Dax in 2367, Jadzia Dax had earned Premier Distinctions in exobiology, zoology, astrophysics and exoarchaeology. (DS9: "Dax")

In 2367, Wesley Crusher topped his class at Starfleet Academy in exobiology, but still struggled with Ancient Philosophies. (TNG: "The Host")

Keiko O'Brien taught xenobiology in her classroom aboard Deep Space 9 in 2369 through the application of a module entitled "Comparative Xenobiology". (DS9: "A Man Alone", "The Nagus")

In 2375, The Doctor wished to consult a database on exobiology when a cytoplasmic lifeform attached itself to B'Elanna Torres. He instead ended up creating a hologram of Crell Moset (Medical Consultant Program Beta one), a Cardassian exobiologist. (VOY: "Nothing Human")

Later that year, when The Doctor gave Qatai information on how to improve his shields, Qatai commented The Doctor seemed to know a little about everything including exobiology, medicine and shield harmonics. (VOY: "Bliss")

Background information Edit

In the retconned material of TNG: "The Neutral Zone", Thomas Raymond was a professor of exobiology. In the remastered version he was a professor of exosociology.

According to a deleted scene in TNG: "Remember Me", when Doctor Beverly Crusher inquired to Cara Hill about her husband Richard Hill, the confused Cara responded, "I am not married. I've never been married – except perhaps to exobiology."
