RRQ make up - the island of Dr.moreau

In this book i wonder . What if a person can actually mess around with human and animal DNA. To make a different kind of creature. For example in the book Dr.moreau makes a creature that's part ape part cheetah and other creatures that look and sound disturbing. I wonder if we in the further can actually do this in the further and what would happened. It really makes me wonder because i seen movies were people do that and it turns out all messed up. Most of what i really wonder is if we could do this what would really happened. Its something i really wonder.
