Difference from human embryogenesis
Most mammals develop similarly to Homo sapiens; during the earliest stages of development, the embryo is largely indistinguishable from another mammal. However, there are phenomena found in human beings not found in all other mammals, as well as phenomena occurring in other mammals, but not in humans.
Mammals do not necessarily have the same human chorionic gonadotropin released from their embryo.
The anatomy of the area surrounding an embryo or fetus, however, is different in litter-bearing animals compared to humans: each unborn animal is surrounded by placental tissue and is lodged along one of two long uterine horns rather than in the center of the pear-shaped uterus found in a human female.
