Apex Wolf pregnancy explained (mpreg)

Some quick Apex lore! >D How exactly does a Wolf pregnancy even work? Well, kinda how it works for some sharks... The majority of that bulge that's weighing Luca down isn't actually the baby, it's the tissue the baby's wrapped in. Baby Wolves need meat, even while inside the womb. The baby's tightly packed in nutritious & delicious placenta all around, when it gets too tight, it will give the baby an urge to dig out more space. Enticing it to feed. This is what's making Luca spit blood, when his baby gets too eager and ruptures stuff that isn't placental tissue. The placenta itself doesn't have any nerve ending, so that part doesn't actually hurt. Will still give you an odd feeling, to be sure...

The placenta and the hormones it produces may have played a crucial role in the evolution of the human brain, while also leading to the behavioral traits that have made human societies able to thrive and expand, according to a new hypothesis proposed by researchers from the Universities of Cambridge and Oxford. Dr. Alex Tsompanidis, senior researcher at the Autism Research Center at the University of Cambridge, and the lead author of this new study, said, "Small variations in the prenatal levels of steroid hormones, like testosterone and estrogen, can predict the rate of social and cognitive learning in infants and even the likelihood of conditions such as autism. This prompted us to consider their relevance for human evolution."
