Are there other mammals - besides humans- that become impregnated "anytime" as opposed to having to go into "heat"?


Human females can not become pregnant at anytime. There is only a short 36 (+/-) hour window once every 28 days that human females are fertile. Now, unlike animals that use estrus, human females do not have a clear signal that indicates when they are fertile. That may be your inquiry intent?

Scientists should not jump to the conclusion that humans do not "signal". There is some evidence that they do...and assuming that since we do not have knowledge of something negates its existence is presumptuous...on the part of science (not you)...:)
