"I just love scanning for lifeforms. Lifeforms... you tiny little lifeforms... you precious little lifeforms... where are you?"
"Our mission as Starfleet officers is to seek out new lifeforms so we can learn about one another."
– Miles O'Brien, 2369 ("Captive Pursuit")

DNA, the genetic programming of a lifeform

A lifeform, while not having an exact definition, is generally an entity which is able to act in its self interest or self preservation through some level of comprehension. The study of lifeforms is known as biology, and, when dealing with alien lifeforms, could be further sub-categorized into xenobiology and xenology.

Criteria for determining whether something was a lifeform ranged from the ability to assimilate to its surroundings, respirate, reproduce, grow and develop, move, secrete, and excrete. Regardless, these criteria rarely defined the physical makeup of a lifeform, as organic, inorganic, and artificial entities have been considered lifeforms. (TNG: "Datalore"; TNG: "Home Soil"; TNG: "Elementary, Dear Data"; TNG: "The Measure Of A Man")

Most space-faring civilizations built devices to remotely detect and locate known lifeforms. Starship sensors and tricorders were the primary instruments used, as they could identify or localize blood type, heart rate or metabolic setup. Typically, only organic lifeforms were detected. (TNG: "Home Soil")

There are incredible similarities between the lifeforms on different worlds in the Star Trek universe. A probable explanation for this may be the existence of the ancient humanoids DNA during evolution.
