Re: Homosexuality, disease?Natural form of Evolution to control our population?
I'm not a biologist by any stretch of the imagination, but I am familiar with some research regarding gender identity and biological causes. There has been a long term study in the Netherlands that have demonstrated changes in the Bed Stria Terminalus (BST) in the hypothalamus in the brain - it's larger in males than females and in male-to-female transsexuals, the BST is closer is size and shape to a genetic female's BST. Due to the small sample group, it hasn't yet been determined if this difference is due to genetic reasons or may be caused by other sources, such as hormone therapies.
Dr. Eric Vilain, a urologist at UCLA, who has done a lot of genetic research in gender identity issues has reported in 2003 that there are 54 different genes in the sex chromosomes that may have an influence on gender identity.
Dr. Joan Roughgarden, a biologist at Stanford, authored a book, "Evolution's Rainbow: Diversity, Gender, Sexuality in Nature and People", which makes a case for how homosexuality and transgender identities can have an effect on natural selection.
As a note for the person stating that "homo" is Greek for man and the root for homosexuality. "Homo" in Latin means "the same" - this is the root word for homosexuality.
Universities claim to prepare students for the world. How many actually do it?
- Many university mission statements do not live up to their promise, writes Ben Nelson, founder of Minerva, a university designed to develop intellect over content memorization.
- The core competencies that students need for success—critical thinking, communication, problem solving, and cross-cultural understanding, for example—should be intentionally taught, not left to chance.
- These competencies can be summed up with one word: wisdom. True wisdom is the ability to apply one's knowledge appropriately when faced with novel situations.
This is what the world will look like, 250 million years from now
To us humans, the shape and location of oceans and continents seems fixed. But that's only because our lives are so short.
As a doctor, I am reminded every day of the fragility of the human body, how closely mortality lurks just around the corner.
Tyson dives into the search for alien life, dark matter, and the physics of football.
- Astrophysicist Neil deGrasse Tyson joins us to talk about one of our favorite subjects: space.
- In the three-chaptered video, Tyson speaks about the search for alien life inside and outside of the Goldilocks Zone, why the term "dark matter" should really be called "dark gravity," and how the rotation of the Earth may have been the deciding factor in a football game.
- These fascinating space facts, as well as others shared in Tyson's books, make it easier for everyone to grasp complex ideas that are literally out of this world.
SpaceX's momentous Crew Dragon launch is a sign of things to come for the space industry, and humanity's future.
