After some arboretum visits Dr. Crusher diagnoses nothing serious, but soon dozens of crew members get behavioral deviations, affecting appetite, memory and emotions. Reg Barclay takes care of Data's cat Spot, who is pregnant like nurse Alyssa Ogawa. Worf first fails testing or diagnosing his new guidance system, so Picard and Data chase a lost torpedo, then bites Deana and turns into an erratic beast due to a bite a sprays venom himself. By the time Picard and Data return, everyone aboard seems mutating and/or molested: the Enterprise has become a 'de-evolution zoo', Data believes by a virus reviving dormant genes from ancestral species. Picard is also infected, causing growing prey-anxiety. Nevertheless he must lure monstrous Worf away so Data can develop a retrovirus from genetic material after finding Spot's kittens remained perfectly feline when ma turned iguana. Written by
Did You Know?
Introns are non-coding gene sequences switched off in an organism's evolutionary history. But outside of that basic fact, the episode's knowledge of introns is sketchy at best. As introns have altered, shuffled and deleted over the eons, the actual effect of switching on these sequences would probably kill an organism. See more
When Data and the captain return from recovering the torpedo from the asteroid belt, the Captain orders Data to adjust the shuttle's attitude to match the Enterprise before they land. This is a pointless command, matching speed, orientation and rotation of one ship to the other would be part of the normal approach and landing process, and would not require a separate command.
Again, once on-board the Enterprise, he issues direction to Data, and states that he, himself, will take care of the 'attitude' of the ship. There is no up or down in space, and the attitude of a ship is meaningless unless measured in relationship to another object. Gravity is created artificially in a local environment on board the ship. There is no reason to adjust the 'attitude' of a single ship in open space. See more
