Not only the Anunnaki would have practiced genetic engineering in the ancient past... The later Atlanteans would have succeeded in it too.
In the readings from Edgar Cayce there is the mention of beings which were both half man and half beast who lives on the earth until 9,000 BC. Because they were not fully human and usually merely had low animalistic intelligence, these beings were also called the "things" or "automatons". They were being exploited as work slaves for the hard work that didn't require much intelligence. At a later time, this caused a great ethic problem between those of the factions of the sons of Belial - who wanted to keep exploitating them - and those of the Law of One - who proposed more rights, freedom and room for spiritual development for these beings.
Edgar Evans Cayce (Edgar Cayce's son) explained these beings in his book: "Edgar Cayce about Atlantis" (1988), as the result of genetic engineering. The subject and possiblity of genetic engineering was still unknown during the time of the readings of Edgar Cayce, thus had not been specifically mentioned in his readings. The first genetically modified organisms were bacteria generated in 1973 and genetically modified mice in 1974.
The channeled book: "Nefratete, Priesteres in Atlantis (1997)" (Priestess in Atlantis) by Joke Bouwsma briefly described the existence of these half man, half animal beings as secret genetic experiments the common people did not knew about. Their masters used some form of mind control to keep them obedient.
Dr. Cottrell's e-book: "Atlantis Revisited" stated that human
cloning would have been achieved by the ancient Atlanteans. Also
according to Dr. Cottrell and Daan Akkerman they would have
experimented with genetic engineering where
they combined elements from both human and beast.
According to the readings of Daan Akkerman (from: "Lanto 1: Atlantis"), man generally was an emotionless being during the later era of Atlantis (although there were exceptions) that was also still in contact with the fallen angels. These fallen angels however, at that point in time, had lost the ability to manifest themselves in physical bodies due to the further densification of matter, which was the result of the last great changes to the connections of the electro-magnetic grid of the earth during the second catastrophe of Atlantis. They could however bind themselves to physical man, and ever tried, through man, to create a being without free will that they could form to their own insight. (Those slave workers that Edgar Cayce called the "things".) Through man, they carried on with genetic manipulations at humans, animals and plants, which caused the existence of monstrous creatures, and also the existence of giants and dwarfs. (Possibly this is why the Book of Giants also mentions the appearance of "monsters", apart from the giants.)
Perhaps this is why the Book of Giants mentions "monsters", besides giants. It would appear that these monsterous creatures from Greek mythology - like the Chimera (a creature with the body of a lion (or goat) and the heads of a lion, a goat and a snake as tail) and the three-headed head Cerberus - were also the results of genetic experiments from those times.
Lytle Robinson also mentioned these mixtures based on the Edgar Cayce readings in his book "Edgar Cayce's Story of the Origin and Destiny of Man (1972)":
"Overcoming the monstrosities, the mixtures and the animal influences was accomplished through rebirth, surgery and evolution towards a more divine purpose. The animal influences finally disappeared about 9000 B.C. Remnants of these creatures, with their appendages of wings, tails, feathers, claws and hooves were later depicted accurately in Assyrian and Egyptian art. The sphinx is a notable example of one of the earlier monostrosities."
In his readings, Edgar Cayce mentioned the so-called "Temple of Sacrifice", which was a spiritually based hospital or health center, and the "Temple Beautiful", which was a school of higher learning and vocational traininig. According to Edgar Cayce's material, these temples had nothing to do with human or animal sacrifices but instead the sacrifice of the ego and selfishness was meant, to develop oneself in the way to a more divine purpose. Edgar Cayce mentioned that there were such temples in both Altantis and in (early) Egypt around 10.000 BC.
These centers gave hope to these "things" that their bodies could be transformed, to heal the body and soul and also to get rid of the animalistic influences which had perverted those beings on a large scale. These reliefs seen above may have to do with the rituals performed in those centers.

body was shed of the animal representations through the sacrificing

Treatments for correction of bodily and mental deformities were accomplished not only through the use of surgery, medicines, electrical therapy, massage, spinal adjustments and the like; but by diet, the vibrations of music, colours, dancing, song, chanting, and most important ones; by keeping a state of profound relaxation and meditation, both for the raising of the spiritual vibration and vitality within the body so that the body will recover better and thus sooner. (Hurt, fear, worry and stress actually lowers one's vibration and should be resolved or avoided as much as possible). There is actually a tight relation between mind and matter where scientists are in present time are just scratching the surface with their theories about quantum mechanics.
passage of individuals through the experiences in the Temple of
Sacrifice was much as would be in the hospitalization, or a hospital
of the present day, when there have become antagonistic conditions
within the physical body, such as to produce tumors, wens[cysts],
warts or such.
Magnify this into the disturbances which were indicated, or illustrated in conditions where there was the body or figure of the horse, or the head of the horse with the body of man; or where there were the various conditions indicated in the expressions by the pushing of spirit into physical matter until it became influenced by or subject to same. Such influences we see in the present manifested as habits, or the habit-forming conditions.
Then there are, or were the needs for the attempts to operate, as well as to adhere to diets and activities to change the natures of the individuals; that their offspring, as well as themselves, might bring forth that which was in keeping with--or a pattern of--those influences in which there were souls or spirits with the idea, or ideal, of seeking light."

Also according to Dr. Douglas James Cottrell, the Temple Beautiful was a regeneration place for those that were the victims of these genetic experiments and suffered from it. The temple complex of Angkor Wat in Cambodia would also have been a health center that was similar to the "Temple Beautiful" and the "Temple Sacrifice", which had been built by those that had migrated from Atlantis (Poseida) and settled within this region. It would originally have been constructed some 10,000 years ago.
At these temple complexes there are also depictions of humans with animalistic features, like people who are seen with the tail of a snake in place of human legs (called the "Naga"). (Source: "Douglas James Cottrell PhD: Secrets of Angkor Wat", by Rammsteinregeln.)
