Answer:

Option C,  Earth's temperature was too high for solid rocks to form.

Explanation:

During the Hadeon age ( some 4.6 billion years ago), the earth was at its initial stage of formation. By that time the temperature of earth was extremely high and extraterrestrial bombardments from  other planets or celestial structures further raised the earth’s temperature. Due to such extremities and high temperature the rocks at the surface of earth could not solidify and hence no traces of rocks can be found from the Hadeon era.

True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.
Debora [2.8K]

It is true that it is possible for a population to not evolve for a while.

There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.

There are 5 Hardy-Weinberg assumptions:

  • no mutation
  • random mating
  • no gene flow
  • infinite population size
  • and no selection (natural nor forced).

You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.

For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.

Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.
