Eve (Dr. Who's Time Tales)

Eve was the wife of Adam. They were believed to be the common ancestors of the whole of the modern human race.

Biography
Their descendants had no concept of humanity's history before Adam and Eve, but according to the Fourth Doctor, Eve and Adam were not actually the first modern man and woman. Instead, they existed in an advanced human civilisation, quite similar to the later human society of the 20th century onwards. Eve was many centuries younger than Adam, who, thanks to a unique serum he had invented, was 930 years old, but physically in early middle age, when Eve met him.

In Eve's era, concerns about overpopulation had led the entire human race to decide to transplant themselves to another, recently-discovered planet with more space and resources. Save for Adam, who refused to leave because the Earth had been his home for so long, Eve was the only human being who decided to stay behind on Earth when the great fleet of rocket-ships eventually departed for good. By then, she had a few friends, but no family; the friends called her mad when she professed her intention to stay. She and Adam met some time before the departure in question, and bonded over their shared resolve to remain among the last Earthlings. After watching side by side as the last ships took off, Adam proposed to Eve, and she accepted, with the two considering themselves husband and wife from that moment on, with no need for ceremony.

Eve suggested that they spend their lives trying to lay the foundations for a new civilisation, giving humanity a fresh start on the abandoned Earth, where, as the rest of the population turned all its energy to building the starships, nature was already starting to erase the traces of the earlier civilisation. Adam agreed with Eve's project, noting that they would not tell their children about what had come before, such that their descendants would believe human history had started with the two of them and remain unaware of the large human population who had left for the stars long ago.

Legacy
Adam's supposition that their descendants would remember "Adam and Eve" was fulfilled. The Fourth Doctor, when telling the time tale of Adam and Eve's true origins, seemed to assume that his audience would be familiar with the principle of Adam and Eve, yet surprised by their origins, just as Adam predicted. (COMIC: Dr. Who's Time Tales) Clyde Langer compared himself and Rani Chandra to Adam and Eve when the rest of the human race disappeared from the Earth, leaving them as the only two.

Their names also entered popular slang, removed from their context. While pretending to be Rose Tyler, Cassandra O'Brien.Δ17 borrowed what she thought was a 21st century colloquialism, and said "I can't Adam and Eve it"?. (TV: New Earth) While pretending to be a native 19th century Londoner, Strax used the phrase "Can you Adam and Eve it?" Jenny had been giving him "assimilation training" lessons, which he was happy to put to use in the subterfuge. (AUDIO: The Cars That Ate London!)

Behind the scenes
and, in the Bible, were the first humans created by God after he created the rest of the world. They lived in the Garden of Eden before getting banished; according to Christian theology, due to original sin.

"Adam and Eve" is also Cockney for "believe".
