sixpenceee:well-done-padawan:sixpenceee:The egg of a mammal is surrounded by a structure called the zona pellucida. It place an important role in species-specific recognition. Scientists know this because when the zona pellucida was removed from a human egg and exposed to hamster sperm, it resulted in fertilization. A hamster-human hybrid zygote was formed. But this zygote did not survive it’s first cell division. A HAMSTER-HUMAN HYBRID? I think this was one case in which science actually did go too farImagine they created an optimal environment for a half animal-half human hybrid to survive -- source link
