When you think about human evolution, there’s a good chance you’re imagining chimpanzees exploring ancient forests or early humans daubing woolly mammoths on to cave walls. But we humans, along with bears, lizards, hummingbirds and Tyrannosaurus rex, are actually lobe-finned fish.
An analysis of the 1.5 million-year-old cranium DAN5/P1, found at the Gona site in Ethiopia, has cranial cranial morphology which indicates that it belongs to the species Homo erectus but near the earliest African stage, where it is sometimes identified using the name H. ergaster.
The fossil is very small for these hominin groups and suggest that its cerebral morphology does not present any traits distinctive to the human genus: its proportions are similar to those of australopiths or species whose evolutionary position, and whether they are from our own lineage, remains to be determined, as is the case with H. habilis.
DART, NASA’s successful double asteroid redirection test in September 2022, had an impact greater than engineers expected - and that means the ability to more accurately move asteroids on a collision course will be greater in the future.An analysis of the results
found the momentum was significantly enhanced by the recoil created from streams of particles produced by the impact.
Food and energy are strategic resources and since conventional energy like oil is presumably finite, its extinction first said to be 30 years ago, the rationale has been to subsidize and mandate alternatives like solar and wind schemes.
Food is also subsidized because it is a strategic resource but the curve is going the other way. Instead of being depleted 'real soon' as environmental PR gurus like Jeremy Rifkin successfully convinced journalists to repeat about oil decades ago, we have so much food that for the first time in human history poor people can afford to be fat. And with affordable food, culture improves, as do lives. The world exceeded UN targets for improvement of the poor by nearly half a decade.
In almost every case, someone being called a Nazi or Fascist on Twitter is being called such by someone who never knew any of those, and is probably a second or third generation descendant who didn't know any either. I had one grandfather who went across North Africa and one who occupied Japan but to my knowledge neither had any special claim to knowing about the Axis powers.
Autism is a neurodevelopmental disorder that affects communication, social interaction, and behavior, with a prevalence of one in 54 children in the United States. While there is no cure for autism, there are several therapies that can help children with autism improve their communication, social skills, and behavior. However, autism is often discussed in ways that suggest that autistic people are subjects who cannot actively participate in their own treatment, and this has led to autism treatments that do not benefit autistic people
being promoted.What is Autism?
If you believe your electric car is not using the 80 percent of electricity generated by conventional fuels, you may also believe the high cost is worth it to save the environment. But there is no running from the environmental problems created by the cars themselves.
There can be no sustainable value chain when we haven't had new batteries in 30 years. Unfortunately, as long as mandates and subsidies are in effect, there is no incentive to create better technology, which means the only hope is to reuse old, inefficient batteries in order to mitigate the high social and environmental toll electric cars extract now.
Right now, 17 percent of the US is cropland
while 51 percent is open and essentially unused. We have more open space in the US than the entire continent of Africa, only 3 percent of our land is urban, but you might not be aware of that because activists insist that urban blight is ruining the country.
The complexities of the human brain and its underlying genetic and biological mechanisms are truly fascinating. A recent study by scientists at Aarhus University sheds new light on the genetic factors underlying attention-deficit/hyperactivity disorder (ADHD), a common neurodevelopmental disorder affecting millions of people worldwide.
By studying over six million genetic variants in nearly 40,000 people with ADHD and almost 187,000 without ADHD, the researchers identified 27 genetic risk variants for the disorder. These risk genes are expressed in the brain and neurons, particularly dopaminergic neurons, which play a role in reward response and the concentration of dopamine in different brain regions.
The Importance of the Study
If you have ever seen pictures of people doing yoga with goats
or sunning their butt-holes
(1), you may have assumed it is California, but that is unfair. It is just as likely to be any state on the west coast.
