How do you explain the uh switch from
Asexual reproduction to sexual reproduction?
Well first off let me say that
That in no way challenges the validity of biological evolution
Whether we're able or unable
Tremendous variety of dogs on the planet
And in fact they are manmade dogs in a way
Exactly where did they come from?
We humans made them
By controlling which dogs shall mate with which
Compare that with four billion years of biological evolution
Not artificial selection but natural selection
Which goes into
Not just the the over characteristics and personalities of the dogs
But into the biochemistry into the internal organs
Selecting what works a little bit better
Just the faintest bit in the competition of organisms
And then it is clear
That the beauty and diversity of life on Earth
Can emerge
But into the biochemistry into the internal organs
Selecting what works a little bit better
Just the faintest bit in the competition of organisms
And then it is clear
That the beauty and diversity of life on Earth
Can emerge
