In the previous article, we shared how to respond to someone who tries to persuade you that swearing ruins DNA, drugs, and unprotected sex lead to AIDS and that the first woman’s partner may influence her future baby’s DNA from another man. Today we publish the rest of the text. Enjoy getting more of the Smart Ass.
Myth 4: Men’s ancestors were hermaphrodytes.
The idea is partially based on the fact that men have nipples! For some scientists, it’s enough to make such a strong statement, which opposes the classical theory.
This argument was mixed with the fact that mitochondrial Eve and Adam lived with a time gap of at least 40k years. So, someone concluded that there were only women who could fertilize and give birth during this period. Of course, it can’t be so; otherwise, we would see some of the hermaphrodites among us, but we don’t.
The time gap between “Eve” and “Adam” means that we inherited mitochondrial cells from one woman, but other chromosomes – from many other women living in different times. The same with “Adam,” men always inherit Y-chromosome to men only, and we can track when the first man lived, but it doesn’t mean he needed to be with the first “Eve.”
Myth 5: All humanity is descendants of Adam and Eve.
The myth is connected with the previous one.
Whereas we have one significant “evidence” of two people who gave birth to all humankind, The Bible, it’s not scientifically proved.
The myth comes from a wrong understanding of what mitochondrial Eve means. In fact, “Adam” and “Eve” never met as they lived far from each other from a historical perspective. All people came from many people, not from just two people.
This experiment proves it. To explain all the current genetic diversity, you’ve got to have a specific size when people first came out of Africa. Based on this, we know that the African population had to be around 7K of sexually interactive humans.
Myth 6: We use only 10% of our brain capacity.
This idea comes from misunderstanding one case of hydrocephaly when the brain gets damaged and with years filled with liquid. In this particular case, the person had almost 70% of the brain replaced with the fluid and still could function kind of normally (he was a civil servant). So, some suggested that we don’t need the full capacity to survive.
The alternative hypothesis says that we use the full capacity, but never simultaneously. You can see it in a tomograph when a person does different actions; different brain sections get activated. We don’t need all of them to be active at the same time. Suppose you know how a person is experiencing an epileptic seizure looks. In that case, you might note that he’s far from finding solutions to hard intellectual tasks.
Now you know what to answer to some of the myth-lovers with bare facts on your hands.
