Re: If Monkeys Come Before Us....
It seems to me that our evolutionary line has pretty much reached its end. We have become so good at adapting to our environments through technology that there is no motivation for us to evolve, except in our way of thinking. Any disaster so cataclysmic that it would force us to evolve, instead of just causing our brains to adapt, would likely wipe us out completely. If that didn't happen, it would depend entirely on what sort of disaster it was: if most of the world floods, perhaps we would become amphibians. If it was a massive species extinction, we would need to change our diets, and probably shrink so we wouldn't need as much energy. It's impossible to say what we would become. This isn't to say that humanity is perfect, or that there won't be evolution in other creatures, perhaps producing beings that will take our place of dominance, but I believe the human race is the end of our line. Another branch on the tree of life may grow and surpass us, but we're stuck the way we are.

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
