    Do you think that maybe when our brains shrank, it didn't decrease the amount of neurons, just compressing the brain for quicker information transfer in neurons, technically making us smarter?

    Look at the structure of auxin and melatonin side by side on two screens. For even more fun, look at the structure of chlorophyll and the hemoglobin heme group on two screens. Remember one is for a plant and the other for animals. (I was a Forestry major at a land grant school. We know stuff.)

    Honestly, it's not the materials and the manufacturing methods that are the problem, environmentally... no matter what technology and techniques we choose, use and develope, we will always tip the scales of economy and exploit it until it is no longer sustainable and or efficient. We simply have to build less!!!

    Plants feel pain too. Just because you can't see them feeling it or communicate with them, doesn't mean that they don't. So let's stop farming plants for food, because it's really sad for them.

    Of course cheetahs and greyhounds can run faster than us. Even if their feet touched the floor for the exact amount of time ours do they have four to our 2. You double the feet at the same speed and double the amount of force applied ergo, go faster. I always have a problem running and it is due to weight or the lack of it. My muscle mass was always "right" for my age but my physical weight was around 2 thirds what it should be. Thus when I get upto speed my mass can't pull me down fast enough to keep up with the speed my feet are moving and I end up losing power due to not enough ground contact. It is like I end up running on air :~) Oh and btw when at school in races, this sucked. I was by far the fastest over quick short sprints like in the playground and the bullies are chasing you but favoured races like the 3000 and 5000 and cross country because I could run for ages with me not weighing a lot. How difficult is it to make sure you have the right amount of mass to get the most "use" from your muscles? Also would that be measurable since everybody is different and there could be no "baseline" number to work from?

    Wow! This must be why my classmates in grade school introduced themselves as brother and sister who are not twins but were born on the same year but not the same month. They said they were born 3 months apart so as a child who didn't know any better, i just thought the sister was a very premature baby. I guess they were a product of superfetation, awesome!

    Any advancement in the diagnosis of disease would be welcome. I got sick at the age of 15. Despite seeing a lot of doctors, herbalists and naturopaths it wasn't until just before my 50th birthday I was finally diagnosed. It only took 34 years. Lyme disease. In Australia. The powers that be still say it doesn't exist.

    It could turn out to be the most effective form of population control (survival of the fittest - or at least the less stupid). Anti-vaxxers are ridiculous but they've already reproduced, now they're increasing the chances of their genes being removed from the gene pool via their own stupidity. It's cruel, but more selective than a mass plague of some sort.
