The answer starts in antiquity, when planets and gods were almost synonymous. Another gene, AMHY, is responsible for the emergence of Y chromosomes in monotremes and appeared some 175 million years ago. The symbols themselves are ancient, and the associations they make date back to the dawn of civilization. I’m fine with moving to squares and circles representing respectively male and female, but let’s not be dishonest. By studying samples from several male tissues -- in particular testicles -- from different species, the researchers recovered the Y chromosome genes from the three major mammalian lineages: placentals (which include humans, apes, rodents and elephants), marsupials (such as opossums and kangaroos) and monotremes (egg-laying mammals, such as the platypus and the echidna, a kind of Australian porcupine). It's All in the Y Chromosome, How Fragile X Syndrome Disrupts Perception, Is It a Boy or Is It a Girl?

Physically transitioning from male to female is a unique, individual, but hard process. Think about plants that are neither male or female, but reproduce sexually with some help (bees or the wind). Related terms include cissexism and cisnormativity . The study shows that the same sex-determining gene, named SRY, in placentals and marsupials had formed in the common ancestor of both lineages around 180 million years ago. As with the Trident of Neptune symbol, these planetary symbols were mostly pictographs long before there was any need for illogical contortions like the feminist claim that the mirror is actually the sign for a distaff.

It means that together as male and female they are to image-forth the glory of God and together as fellow-heirs they are to inherit the glory of God. That would be an example of the go betweens from something that reproduces completely asexually to something that has a distinct male and female that are required to produce offspring.

Of course, sin has affected everything, including gender, and, as a result, some people have a real struggle with gender identity. Ashley W. asks: Where did the male and female symbols come from? It then progressively shrank to such an extent that, nowadays, it only contains about 20 genes (the X carries more than one thousand genes). Male circumcision involves much more than just a nick there are no laws in the US to protect them. Representing two planets, iron, copper and a couple of Olympian gods, the classical symbols for male and female pack a lot of meaning into a few squiggly lines.

Mary Jo’s Response: For the sexes to arise by evolution, both male and female and all their complex complementary reproductive parts would have needed to “evolve” by random, chance natural processes in the same kind of organism at the same time and same location, or natural selection would not have “saved” these wonderfully miraculous accidental mutations as they would not provide functional … ScienceDaily.
