Bing says: "Evolution refers to the change in heritable characteristics within biological populations over successive generations". In Genesis 30 Jacob made a deal with his father in law that He would take ownership of all the speckled and spotted sheep and goats as his wages. He then used selective breeding to create sheep and goats for himself. He also breed the strong animals and not the weak ones.
True. But that does not demonstrate evolution.
It is simply genetic combination and does not speak to the idea of creating new genes over time or creating new chromosomes having new genes over time. IF all evolution had was the same genes being combined over and over again - there would be no new species.
In the example above the goats are still goats no matter the color of their hair.
This demonstrates evolution theory and Jacobs understanding of how selective breading where his father in law only understood natural selection. This story demonstrates how knowledge of genetics can impact breeding outcomes.
actually the Gen 30 story shows that Jacob knew almost nothing about genetics.
Gen 30:
37 Now Jacob took for himself rods of green poplar and of the almond and chestnut trees,
peeled white strips in them, and
exposed the white which
was in the rods. 38 And the
rods which he had peeled, he set before the flocks in the gutters, in the watering troughs where the flocks came to drink,
so that they should conceive when they came to drink. 39 So the f
locks conceived before the rods, and the flocks brought forth
streaked, speckled, and spotted. 40 Then Jacob separated the lambs, and
made the flocks face toward the streaked and all the brown in the flock of Laban; but he put his own flocks by themselves and did not put them with Laban’s flock.
41 And it came to pass,
whenever the stronger livestock conceived, that Jacob placed the rods before the eyes of the livestock in the gutters, that they might conceive among the rods. 42 But when the flocks were feeble, he did not put
them in; so the feebler were Laban’s and the stronger Jacob’s. 43 Thus the man became exceedingly prosperous,
Jacob manipulated the breeding by having the stronger animals breeding while looking at the striped rods - thus all the offspring of the strong - were speckled and or spotted -- and not solid. That was Jacob's "understanding".
THEN in Gen 31 - God "corrects Jacob" and gives him a lesson in GENETICS that mankind was not aware of until many centuries after Gen 31.
10 “And it happened, at the time when the flocks conceived, that I
lifted my eyes and saw in a dream, and behold,
the rams which leaped upon the flocks
were streaked, speckled, and gray-spotted. 11 Then the Angel of God s
poke to me in a dream, saying, ‘Jacob.’ And I said, ‘Here I am.’ 12 And He said,
‘Lift your eyes now and see, all the rams which leap on the flocks are streaked, speckled, and gray-spotted; for I have seen all that Laban is doing to you. 13 I
am the God of Bethel, where you anointed the pillar
and where you made a vow to Me. Now arise, get out of this land, and return to the land of your family.’ ”
Instead of God showing Jacob "behold the animals a looking at your striped poles and having spotted, speckled, streaked offspring" - God says "the RAMS which are mating are streaked, spotted, speckled". God was intervening so that only the spotted, speckled, streaked Rams were mating.
Today they call this animal husbandry
Indeed they call what GOD did in selecting the males with the streaked, spotted, speckled feature manifest in phenotype -- animal husbandry.
But nobody today gives any credence to the idea of animals mating in front of striped poles.
