One of the Creator's many reasons for reproduction of offspring is to bring out the genetic diversity He built into the Creation---the blooming Rose of Creation of different shapes, sizes and colors.
When understood this way---it shouldn't be puzzling to "scientists".
And God blessed Noah and his sons, and said unto them,
Be fruitful, and multiply..
Genesis 9:1
"The downsides of relying on sex to reproduce are undeniable: It takes
two individuals, each of whom gets to pass on only part of their
genome. Because these individuals generally have to get fairly intimate,
they make themselves vulnerable to physical harm or infections from
their partner. Asexual reproduction, or self-cloning, has none of these
disadvantages. Clones can be made anywhere and anytime, and they receive
the full complement of an individual’s genes.
Yet despite all its benefits, asexual reproduction is the exception,
not the norm, among organisms that have compartmentalized cells
(eukaryotes).
In plants, for example — which are somewhat known for
their genetic flexibility — less than 1% of species are thought to
reproduce asexually often. Among animals, only one out of every thousand
known species is exclusively asexual. For centuries, biologists have
pondered this apparent paradox.......the purpose of sex is simple: It increases genetic diversity in the pool of offspring.... the geneticist Hermann Muller, ..believed he had the answer.
“Genetics has finally solved the age-old problem of the reason for the
existence (i.e., the function) of sexuality and sex,” he boasted." Quanta
