What would happen if the moon was twice as fast as it it now

Ans ; It would have to be closer for it to be in a circular orbit twice as fast. One moon cycle would be 2 weeks instead of 4 so our months would have been based on 2 week cycles making for 24 months. Tides would be less synchronous between days and much more intense because of how close it would be. This would have left a very different land map. Tidal forces would force the moon to rip apart sooner than with it's present orbit creating an important ring system around earth earlier.  

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
