No, but it does mention these monsters;
Chapter 36
30 And there was a day that he brought them to one of the deserts on the sea shore, opposite the wilderness of the people, and whilst he was feeding them, behold a very heavy storm came from the other side of the sea and rested upon the asses that were feeding there, and they all stood still.
31 And afterward about one hundred and twenty great and terrible animals came out from the wilderness at the other side of the sea, and they all came to the place where the asses were, and they placed themselves there.
32 And those animals, from their middle downward, were in the shape of the children of men, and from their middle upward, some had the likeness of bears, and some the likeness of the keephas, with tails behind them from between their shoulders reaching down to the earth, like the tails of the ducheephath, and these animals came and mounted and rode upon these asses, and led them away, and they went away unto this day.
33 And one of these animals approached Anah and smote him with his tail, and then fled from that place.
If they hadn't learned to splice the DNA how else could they have produced these monsters ?
