Barbourofelis fricki reproduced similarly to mammals. The male sperm and female egg would fertilize to create a zygote. The zygote divides. Deuterostomes divide using radial cleavage which makes it possible for them to have twins. As the group of cells divides, it does not increase in size. Eventually the cells move to the outside forming a blastula. The blastula cleaves in  forming a gastrula. The gastrula in deuterostomes forms the anus first. Late in this stage there are three tissues making the organism triploblastic with an inside endodermal layer, middle mesodermal layer, and an outside ectodermal layer.
Protein concentration gradients are set up to help the cell undergo cephalization. The cells will undergo determination, to determine the cell fate, and differentiation, the specialization of the cells. This is again possible because of proteins that turn on or off certain genes, also called gene expression.
