Besides the two hearts and regeneration, is there anything that physiologically separates a time-lord from a human being?

  • There is the whole "being exposed to the time vortex", which surely must leave some kind of mark. But that might be more of a psychological one.

    Is "Arrogance" enough of an answer?

  • @TangoOversway not really, it's not physiological.

    Are you looking for something other than tardis.wikia.com/wiki/Gallifreyan_physiology? I'm not sure what an answer here would add to that.

  • @TonyMeyer That is essentially what I'm after! Thanks for finding it, I didn't think such a list would exist!

  • Two Hearts that beat at 170 BpM
  • Body temperature 59 deg Fahrenheit
  • Respiratory bypass system
  • Survive Vacuum of space, extreme heat/cold, radiation, electrocution
  • Regeneration/healing coma
  • Slower aging
  • "Rassilon Imprimatur" which allows symbiotic link with the TARDIS
  • Minor telepathy
  • Control of some internal body functions

    Many of those attributes are [citation needed] on Wikipedia, and I have doubts about some. For instance, it would be odd for his body temperature to be that much lower and not have every single human remark on it the first time he touches them. Are there better sources for this stuff?

  • @Geobits this wiki has everything referenced. The low body temperature is from non-TV stories.

A Time Lord can see all possible timelines.

Rose Tyler: I can see everything... all that is... all that was... all that ever could be.

The Doctor: But that's what I see. All the time. And doesn't it drive you mad?

Time Lords have been shown to exhibit other various mental powers. All Time Lords can sense and communicate with other Time Lords. They can transfer memories to other beings (at the very least, humans) via a well placed headbutt. The Doctor is shown to have the ability to manipulate the very memories of Donna Noble.

    Most obviously, Time Lords also have a really precise time/space sense. But I'm not sure any of this is physiological difference. Is this actually Gallifreyan biology, or just Vortex exposure? Rose's comment suggests the latter.

  • Right, given viewing the time vortex, possession of a TARDIS, SS, and PP, would a human be that different from a Time Lord?

  • Note that Rose is unable to cope with her exposure to the Time Vortex (as was Donna), so there is some indication that Gallifreyan brains are different than human brains, it's just never explained how.
