According to a new study of the skeletal remains of both mama ants the animal known as Chi ant etherium well Z wasn’t quite a mammal but rather a sign of donned a mantle relative that lived during the Jurassic period and the prodigious number of babies she had is more than twice the average litter.

They traded off small ins and big litter sizes.
