To the contrary, sex (penetration/internal fertilization as a component of reproduction) has 250 million years of history.
In a nutshell, the first animals to walk (crawl, slither, etc) on land were egg-laying amphibians, the eggs of which had to be laid in the sea. Reproduction would have been impossible if they roamed more than walking distance from the sea.
The development of internal fertilization was necessary to support their migrating inland to populate the heart of the continents.
I totally agree that heterosexuality is the truth—a fact of nature-—part of the Laws of Nature and Nature’s God, that makes up the philosophy of our Constitution and Western Civ. which contains our so-called “Justice” (virtue) System.
Words and Ideas and Truth (Objective Truth (God)) matter in our “justice” system which always has to promote truth and “public virtue” to be “just law” (based on Right Reason according to Natural Law).
But, in referring to macro-evolution-—I am lost to that “faith” which is being promoted in all our textbooks, as only Christian faith has been banned from the public square and public skools, so lies and misinformation could be passed on as “truth” instead of just an irrational “theory” of the Marxists and atheists and Humanists and Materialists.
That is how they have flipped 2000 years of ethics and now promote irrational lies (like gender “theory”) and Marxist”s constructs so they could actually make men into women and sodomizing others into a virtue (as they will pederasty), and destroy the rational concept of marriage and make Slavery into Freedom and eliminate virtue formation in our children.
Making Vice into Virtue will make slaves of the masses. Virtue is inner control and not possible without Truth (God). Vice is always outer control and the inability to choose Reason over Emotions; Facts over Lies (Marxism).
