They all knew they were in the presence of God so they were all temporarily absolved of their animal instincts.
They all most likely started grabbing oars in their mouths to help the Ark move.
No they didn't get those animal instincts until after the flood they were vegetarians.
Gen 9:1 And God blessed Noah and his sons. And He said to them, Be fruitful and multiply, and fill the earth.
Gen 9:2 And the fear of you and the dread of you shall be upon the animals of the earth, and upon every bird of the air, upon all that moves on the earth, and upon all the fish of the sea. Into your hand they are delivered.
Gen 9:3 Every moving thing that lives shall be food for you. I have given you all things, even as the green herb.
Gen 9:4 But you shall not eat of flesh with the life in it, or the blood of it.
Humans and Animals were originally Created to eat Only Plants!
Abstract:
Sharp teeth were not part of the creation, they were part of the curse.
Adam, Eve and all the animals were created to eat only vegetation (see comments on Genesis 1:29-30). Nothing died prior to the spiritual fall of Adam and Eve (see comments on Genesis 3:19 and 3:21).
Did plants die in the Garden of Eden?
Plant "death" is different than animal or human death. Plants eat, drink, grow and respond to stimuli, but they do not have a central nervous system. Nor do they have blood. According to scripture only organisms with blood in them are "alive".
“For the life of the flesh is in the blood…”
Leviticus 17:11 (King James Version)
Plants do not die in the biblical sense of the word, because they are not "alive" in the biblical sense.
Humans and animals also posses a state of consciousness that plants can not. The Hebrew word "nephesh" is the word used in the Bible for consciousness. Nephesh is only used in application to man and animals. Plants are not conscious creatures.
Sin brought death to man and animals only. Plants do not truly die in the sense that humans and animals do. Though they are alive in a biological sense, they do not have a spirit, consciousness or soul.
What did animals who appear today as carnivorous eat in the Garden of Eden?
The Bible tells us that when he created the world, all animals ate only plants. But when we look at the animals in the world today we see that many of them have teeth that appear to have been designed for eating meat. Why is this so? Did animals with teeth and sabers once use them to eat vegetation? Or did their teeth change. And if so, how and when?
When we look at the teeth of the first humans (Neanderthals) we see that they had larger molars and smaller canine teeth than we do. They had thicker enamel (they would need this if they lived longer than we do), and had well worn third molars, or wisdom teeth.
God changed the diet of humans in Genesis 9 when Noah got off the ark. I believe that one of the reasons God did this was that many of the plants that had nourished man before the flood had now died off (or were not as plentiful after the flood). Plant degeneration would also effect the nutritional value of plants.
The diet and dentition of animals however changed before this as is evident from the fossil record.
Animal teeth
If animals were created to eat plants then why do many of them have structures that appear to be created to cause harm? Like Tigers, dogs, Etc.?
None of these harmful things existed prior to the curse God placed on the earth when Adam sinned.
Spiders did not spin webs to catch insects. This is one of the many changes that occurred after "the fall". There is no beneficial use for spider webs when spiders ate only plants.
The spiny puffer fish
The spiny puffer (Diodon holocanthus) fish combines pointy spikes with the ability to inflate three times its normal size as a defense mechanism. There would be nothing to defend itself against in a perfect world before sin.
It seems unlikely that God created animals with such harmful structures simply because he foreknew the entrance of sin and death in this world (through Adams sin).
Also the fossils of animals like Heterodontosaurus "Different-tooth Lizard" and simosuchus (sp), australopithecines etc indicate that many features of the masticatory systems did change in animals after the fall. Heterodontosaurus is a stage in between vegetarian and carnivorous.
These were mutational changes occurring only after the fall. This changed benign structures into harmful ones.
Isaiah 11:6-9
“The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them. 7 And the cow and the bear shall feed; their young ones shall lie down together: and the lion shall eat straw like the ox. 8 And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the cockatrice' den. 9 They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea.”
Isaiah 11:6-9 (King James Version)
Hosea 2:18
“And in that day will I make a covenant for them with the beasts of the field and with the fowls of heaven, and with the creeping things of the ground: and I will break the bow and the sword and the battle out of the earth, and will make them to lie down safely. “
Hosea 2:18-30 (King James Version)
One can not even imagine how such things would be useful in a sea of fish that never preyed on other fish. Surely the spiny puffer did not balloon up in order to frighten the vegetation God instructed it to eat.
No, these features (spikes etc) occurred after the fall along with a change of diet for this creature (it now eats: mollusks, crabs, etc.).
Dr. Jack Cuozzo explains one of the many ill effects that the original sin had on the earth:
"Therefore, it is logical to believe that after the Fall, all the harmful isotopes, rays, and gases must have been switched on when God said, "Cursed is the ground because of you" (Gen. 3:17). The restraint in the rocks was removed and the radioactive substances began to open up with a rapid burst, their harmful products possibly still at levels too deep for all of the damaging rays and gases to reach the surface. No doubt, though, some did break through and men and animals began to change immediately post-Fall.
I believe that this is how carnivorous behavior began, with a distortion or breakdown of the genetic messages in tooth and jaw formation. Some herbivorous creatures became carnivorous and were transformed similar to the caterpillar/butterfly transition. Much work needs to be done on this subject, and especially loss of genetic information. Lord willing, this will be my next effort. The radioactive elements probably made an even more disastrous debut on earth as they were spewed forth at the flood when the earth was torn asunder and "all the fountains of the deep burst open" (pg 148 "Buried Alive")
"What happened to the carnivoresÂ’ hinge jaws, razor sharp molars, and six-inch fangs? Did they use them to pounce on watermelons? How could they exist on vegetation? DonÂ’t you suppose that they ate straw like an ox and had different masticatory systems, similar to what they will have again and do again in the new creation described in Isaiah 11:7 and 65:25?" (Pg 98-99 "Buried Alive" by Dr. Jack Cuozzo)
