Effect of time loops on evolution

In summary: However, if I go back to the time of the dinosaurs and don't sneeze, then the common cold would not have existed and the dinosaurs would not have evolved.

It occurred to me that the existence of localized time reversal would manifest an evolution that relies more on free will than genetic determination. The connectivity between two events completing a time loop takes place arbitrarily to Darwinism, either fulfilling spacetime continuity or evoking the ability of the observer to change her destiny.

In both cases, the normally linear progression of evolution would interfere with itself, overwriting entire branches of biological history. Even time-symmetric quantum mechanics may influence microscopic DNA. Adaptation becomes a physical process of participation, rather than a primal matter of survival.

Is this succinct?

Huh?

Loren, I'd like to respond, but I have only a vague idea of what you are trying to get across. The subject is the "effect of time loops on evolution". This is an interesting approach, but I got a little lost in your first post. If you could clarify your meaning, I'd be glad to try to respond. :smile:

Being able to go back in time would play havoc with evolution. Think of the Simpsons episode where Homer sneezes on a dinosaur - but that incident inhabiting one of many "pockets" (some microminiature) in spacetime where an adaptation is trapped or itself changes only locally. Thus evolution could be affected by, restricted to, or temporarily (re)cycled within arbitrary time loops. The more-or-less linear progression that Darwin envisioned would, under this alternative scenario, have a nonlinear timeline changing with space, as well as an environment changing with nonlinear time. Evolution here is greatly relative to the observer.

You know, I hadn't really considered this before. It does, however, remind me of a science fiction story I read once in an anthology of time travel sotries, by Robert Silverberg, called Voyagers in Time (or something like that). The story was called "the Brooklyn Project" (I think) and it was set in the near future. These people were sending two probes into the past and the future, respectively - basically, they would "bounce off of each other" in time. They were convinced that they wouldn't change anything. The announcer had been a typical, portly, man, who liked to yell alot, at the beginning of the story. By the end of the story, he was a purple, gelatinous being, who didn't speak very much, but usually just communicated through his eight pseudopods (or something like that). Anyway, he exclaimed at the end, "You see, nothing has changed!".

If it were possible to go back in time, I believe we would influence our evolution, but not really, because we were "already there". IOW, if I go back the age of the dinosaurs and sneeze, then I (the time traveller from the 24th and a half century :wink:) would have always existed in a world where the common cold (for example) had influenced the evolution of dinosaurs.
 

1. How do time loops affect the process of evolution?

Time loops can have a significant impact on the process of evolution. They can speed up or slow down the rate of evolution, change the direction of evolution, and even cause certain species to go extinct while others thrive.

2. Can time loops create new species?

Yes, time loops have the potential to create new species. When a species is trapped in a time loop, they have the opportunity to evolve and adapt in ways that would not have been possible in their original timeline.

3. How do time loops affect genetic diversity?

Time loops can greatly impact genetic diversity. In some cases, they can lead to increased genetic diversity as species have more time to evolve and adapt to their environment. However, time loops can also cause genetic bottlenecks and decrease genetic diversity if certain traits become advantageous and are passed down through multiple iterations of the time loop.

4. Can time loops cause species to evolve into different forms?

Yes, time loops can cause species to evolve into different forms. This is known as convergent evolution, where different species in different time loops evolve similar traits to adapt to similar environments. Time loops can also lead to divergent evolution, where species in the same time loop evolve in different directions due to differing environmental factors.

5. How do time loops affect the concept of natural selection?

Time loops can have a significant impact on the concept of natural selection. In a time loop, the environment and available resources may change drastically, leading to different selective pressures. This can result in different traits being favored and passed down, leading to a different outcome in evolution compared to the original timeline.
