   What follows is an outline of some of the main areas of concern and disagreement about human reproductive cloning. 3.1 Safety and Efficiency Despite the successful creation of viable offspring via SCNT in various mammalian species, researchers still have limited understanding of how the technique works on the subcellular and molecular level. Although the overall efficiency and safety of reproductive cloning in mammals has significantly increased over the past fifteen years, it is not yet a safe process (Whitworth & Prather 2010). For example, the rate of abortions, stillbirths and developmenta…

   The medical belief* that "ovulation produces estrogen," and that the absence of menstruation means an absence of estrogen, has been very harmful to women's health. Several laboratories, from the 1950s through the 1980s, investigated the causes of age-related infertility. A.L. Soderwall, among others, demonstrated that an excess of estrogen makes it impossible for the uterus to maintain a pregnancy. Subsequently, his lab showed that neither changes in the eggs nor changes in the uterus could explain age related infertility. Altered pituitary hormone cycles, resulting from changes in the brain, …

   And that's what you see in a bunch of primate species that have this sort of structure. Next prediction. You should then predict that when ecological circumstances get tough, when times are tough, you want to go for the offspring that costs less. A female fetus is less calorically demanding than a male fetus. Male fetuses cost more to bring to term than females do. The prediction should be, during times of ecological pressure, the percentage of females being born should increase. And as a measure of the fact that males are more expensive as fetuses, something like 53% of fertilizations in huma…

   And what wound up being clear after a while is there's only a certain pattern that you see in species that have competitive infanticide, which is the average interbirth interval among females is longer than the average tenure of a high-ranking male. What? Here's what that means. That means you're some low-ranking guy. You've been working out in the gym for years on end. You're finally in the position to boot out the alpha male and take over the whole group. And damn, every single female in the group has a newborn who they're going to be nursing for the next two and a half years. So they're not…

   Another technique to produce genetically identical offspring or clones is embryo twinning or embryo splitting, in which an early embryo is split in vitro so that both parts, when implanted in the uterus, can develop into individual organisms genetically identical to each other. This process occurs naturally with identical twins. However, what many people find disturbing is the idea of creating a genetic duplicate of an existing person, or a person who has existed. That is why the potential application of SCNT in humans set off a storm of controversy. Another way to produce a genetic duplicate …

   Over 40 years ago, scientists imagined ways cloning could aid conservation of threatened taxa. The cloning of Dolly the sheep from adult somatic cells in 1996 was the breakthrough that finally enabled the conservation potential of the technology. Until the 2020s, conservation cloning research efforts yielded no management applications, leading many to believe cloning is not yet an effective conservation tool. In strong contrast, domestic taxa are cloned routinely for scientific and commercial purposes. In this review, we sought to understand the reasons for these divergent trends. We scoured p…

   And the thing is you have to realize what happened there is the process of your sperm and your wife's egg coming together. You didn't know that in the muscle skeletal sommites that that effect was there like whatever was the cause of the timing issue that which that which I answered for you in the beginning of the podcast that macro put the heteropasy late ratio in that part of his cell and that's why it happens and you know it the reason why I find this fascinating if you think about doctoring all the way back to 1859 to Darwin ideas about evolution. No one's ever been able to figure out, you…

   Infertile individuals or couples could have a child that is genetically related to them. In addition, individuals, same sex couples, or couples who cannot together produce an embryo would no longer need donor gametes to reproduce if cloning were available (some might still need donor eggs for the cloning procedure, but these would be enucleated so that only the mitochondrial DNA remains). It would then be possible to avoid that one’s child shares half of her nuclear DNA with a gamete donor. Using cloning to help infertile people to have a genetically related child, or a child that is only gene…

   There was no evidence for a difference either in total stress as measured using the PSS or in total positive or negative affect using the PANAS questionnaire between the test and control groups at any time point for the duration of the study. During cycle 1, for example, on Day 6, the difference in total stress score (test-control) was -0.62 [95% confidence interval (CI) -2.47 to 1.24] and on the day of the LH surge, it was 0.53 (95% CI -1.38 to 2.44). In addition, no correlation was observed between time trying to conceive and levels of stress, or between age and levels of stress, and no evid…

    The understanding of both epigenesis and preformation underwent transformation so that the debates brought new questions along with the traditional differences. Darwin pointed to embryology as fundamental for interpreting historical relationships. In Chapter 13 of the Origin he asked How, then, can we explain these several facts in embryology,—namely the very general, but not universal difference in structure between the embryo and the adult;—of parts in the same individual embryo, which ultimately become very unlike and serve for diverse purposes, being at this early period of growth alike;—o…
