A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter. Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment. Also used to describe the process of genetic change within a population, as influenced by natural selection. A graph of the average fitness of a population in relation to the frequencies of genotypes in it.
Plot[ edit ] The crew of the Federation starship USS Enterprise is struck with deadly Rigellian fever, for which the only treatment is the mineral ryetalyn.
They arrive at planet Holberg G in search of the substance. Captain Kirkfirst officer Spock and medical officer Dr. McCoy beam down and are attacked by an airborne robot, which is called off by its master, Flint. Flint orders them to leave immediately, but is finally moved by their plight. Flint gives the landing party two hours, offering the help of his sentry robot M4 to gather the mineral.
Flint then escorts them to his home, which has an impressive art collection, including undiscovered paintings by Leonardo da Vinci. Spock notices that the brushwork of the paintings is identical to Leonardo's, but his tricorder indicates that they are made with contemporary materials.
The party is introduced to Flint's beautiful young ward, Rayna Kapec, whose late parents, according to Flint, were employees of his. On Flint's suggestion, Kirk plays billiards with Rayna, and they dance to a waltz played on the piano by Spock, from a manuscript apparently in the hand of Johannes Brahmsbut written with contemporary ink.
Shortly afterward, M4 returns with a container of ryetalyn, but it is contaminated with irilium, and therefore useless. Flint apologizes and accompanies M4 on a search for more ryetalyn.
Oddities begin to mount up. When Kirk kisses Rayna, M4 reacts as if he were attacking her.
The Enterprise reports that no information can be found on Flint or Rayna. A tricorder scan reveals that Flint is over 6, years old. Rayna comes to say goodbye to Kirk, who has fallen in love with her and begs her to accompany him. McCoy tells them that the ryetalyn is missing, and Spock follows tricorder readings to a laboratory chamber containing android bodies, all labeled "Rayna".
Flint finally reveals the truth. He was born 3, years BCE, and after falling in battle discovered he could not die. Flint has lived "lifetimes" as MethuselahAlexander the GreatLeonardo da Vinciand many others.
Rayna is to be his mate, now that Kirk has taught her how to love. A fight then breaks out between the two men for the possession of Rayna. Rayna stops them, claiming her right to choose her own future, and then, overwhelmed by her newfound emotions, dies.
Kirk falls asleep on his desk wishing to forget Rayna, and Spock places a suggestion to "forget" into his mind. Analysis[ edit ] According to fantasy and science fiction scholar Ace G. It differed from previous science fiction films in several ways. Humans are using faster-than-light starships in the film.
He had the idea to use the play as the basis of the film's action and characters. The screenplay was mainly written by novelist and screenwriter Cyril Hume. Flint hopes that the female android will fall in love with him.
Flint offers her knowledge and intellectual stimulation but Rayna falls for the "irresistible" James T.
The female android faces new and to her unfamiliar emotions, having to choose between two men. The pressure causes her to short-circuit into self-destruction, her version of death.
She is a creation who came to life and was intended to be an immortal companion to Flint. She finds Rayna's story to be similar to that of Galatea from Greek mythology. Galatea was a female statue who came to life and mated with her creator Pygmalion.
He is immortal and apparently unable to die. He has outlived his human attachments and it is hinted he has repeatedly outlived them in his long life. He wants a female android to be his mate, because he hopes that Rayna would also be practically immortal.
His previous loves were apparently mortal women, whom he has lost to the ravages of time. He suffers from the pain of loss.The latest breaking news video and visual storytelling from HuffPost.
