Human-animal hybrid

A human-animal hybrid is when two different kinds of animals (like a human and an animal, like a cow) are mixed together. Scientists take a human cell and an animal cell, and mix them together in a process called "genetic engineering." The resulting hybrid creature is a mix of both the human and the animal, with traits and features from both. It's like if you took a cow and a human, and blended them together so the new creature had some features of a cow, and some features of a human.
