The more you understand about reality…the less satisfied you become…with religious fantasy myth. The more dissatisfied you become…with
religious fantasy myth…the less inclined you become…to give religious sects 10% of your income for life. The less inclined you become…to give
10% of your income for life…the more people and money become available…to solve real life problems…like inequality, poverty, cures for diseases…creating effective climate change and pollution solutions…
“Sperm counts vary from about 20 million to 100 million sperm cells per milliliter of ejaculate. Healthy guys produce from 1.5 ml to 5 ml of semen each time they ejaculate. (That means up to 500 million different sperm cells
each time they ejaculate…!)
Inside a woman’s reproductive tract, a man’s sperm can survive for up to five days (increasing the odds that an egg becomes available for fertilization).
Sperm cells swim about 0.2 meters per hour, or about 8 inches. That’s a lot faster than it sounds, considering how tiny they are!
Scientists believe sperm cells find a waiting egg cell via a couple of complex mechanisms. They swim toward higher concentrations of molecules released by the egg (known as chemotaxis) and toward the high-temperature areas of the woman’s reproductive tract, where eggs are found (known as thermotaxis).
Who discovered sperm cells? That would be Antonie van Leeuwenhoek (1632-1723). The amateur Dutch scientist and prolific lensmaker first observed sperm cells in 1677. Whose sperm was it? His own. Van Leeuwenhoek was also the first to observe bacteria, muscle fibers, and the flow of blood cells through capillaries. No wonder he’s been called the “father of microbiology.”
There is nothing in reality, that supports religious fantasy myths. In fact, to make religious fantasy myths appear more real, it helps to switch off rational thinking…because nothing interferes more with imagining
religious fantasy myths…than understanding reality…!
Understanding how each offspring from the same couple is so different…with unique characteristics, skills, talents and strengths…and further compounding those differences by changing just one of the sexual partners…helps explain the value to a population, of fertilizing a random egg…with a random sperm cell…
“In biology, evolution is the change in the inherited traits of a population from generation to generation.These traits are the expression of genes that are copied and passed on to offspring during reproduction.
Mutations in these genes can produce new or altered traits,
resulting in heritable differences (genetic variation) between
New traits can also come from transfer of genes between populations,
as in migration, or between species, in horizontal gene transfer.
Evolution occurs when these heritable differences become more common
or rare in a population, either non-randomly through natural selection
or randomly through genetic drift.
Natural selection is a process that causes heritable traits that are
helpful for survival and reproduction to become more common, and
harmful traits to become more rare.This occurs because organisms with advantageous traits pass on more copies of these heritable traits to the next generation.
Over many generations, adaptations occur through a combination of
successive, small, random changes in traits, and natural selection of
those variants best-suited for their environment.
In contrast, genetic drift produces random changes in the frequency of traits in a population.
Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
One definition of a species is a group of organisms that can reproduce with one another and produce fertile offspring.
However, when a species is separated into populations that are
prevented from interbreeding, mutations, genetic drift, and the
selection of novel traits cause the accumulation of differences over
generations and the emergence of new species.
The similarities between organisms suggest that all known species
are descended from a common ancestor (or ancestral gene pool) through
this process of gradual divergence.
The theory* of evolution by natural selection was proposed roughly
simultaneously by both Charles Darwin and Alfred Russel Wallace, and set
out in detail in Darwin’s 1859 book On the Origin of Species.
In the 1930s, Darwinian natural selection was combined with
Mendelian inheritance to form the modern evolutionary synthesis, in
which the connection between the units of evolution (genes) and the
mechanism of evolution (natural selection) was made.
This powerful explanatory and predictive theory has become the
central organizing principle of modern biology, providing a unifying
explanation for the diversity of life on Earth…”
Interestingly, over time, even the fabricated gods of religious beliefs are subject to the principles of mutations, natural selection, and genetic drift…with those religious groups unable to adapt to their changing environments…dying out…
Today, religion needs to relinquish texts that anchor members to long discarded forms of immoral behavior** and abandoned values and ignorance…and align itself with humanity’s current understanding of reality…and the need for people to belong to a society that grows in actual knowledge, and cares for each other and their environment, in a sustainable way…putting aside magical/supernatural and wishful (life after death) thinking…and evolve by embracing secular humanism…
* defined in science…as
“a well-substantiated explanation of some aspect of the
natural world, based on a body of facts that have been repeatedly
confirmed through observation and experiment. Such fact-supported theories are not “guesses” but reliable accounts of the real world…” https://en.wikipedia.org/wiki/Scientific_theory
