Imagine what life would be like if human females could put a stop and go on pregnancy depending on the circumstances.

Kangaroos are quite amazing creatures – especially kangaroo mothers. Depending on environmental factors, kangaroo mothers can put their joey embryos into diapause, which means they won’t give birth.

This is also useful for when the mother kangaroo needs to wait until her older joey can leave the pouch to live on his own two feet.

Would this be the wrong time to bring up the fact that kangaroos have some of the healthiest red meat out there because they hold most of their fat in their tails?
