Tracing our origins back to the beginning of life on the planet earth is no easy task.  Sceintists have certainly traced the origin like forms of life.  We have a very good understanding of what types of life sprung from the primordial ooze that 'cooked' life.  This science is called biopoiesis; the study of how biological life could arise from inorganic matter through natural proce... more

Daylight savings time began in an effort to conserve fuel after World War One.  The theory was, if you had more time in the daylight to get stuff around the house done, you would.  That theory has continued, so to co-incide with the lengthening of days, usually around the first day of Spring, most countries will 'Spring forward' by an hour.  It is thought that this, in the U.S. at l... more

The deepest place on the earth is in the Pacific Ocean.  It is called the Mariana Trench and the depth is still under discussion.  The lowest part of the trench is 6.7 miles deep, or 35,800 feet below sea level, although one measurement came up with 6.85 miles.  This is where the film producer James Cameron is going to visit in a sub he helped design for this purpose.  The tren... more

From what I gather they build mounds out of organic material to incubate the eggs. The heat from the composting material helps with the incubation. The megapodes remove and add organic material as needed to keep the eggs at the proper temperature until the eggs hatch. more

It Is mostly due to the curvature of the earth. The different colours that we see are due to the light rays from the sun hitting different molecules In our upper atmosphere. Using a spectrometer you can define what each gas/molecule each colour represents. For example we know blue represents water molecules etc. more

The studies that investigated this question have generally yielded the same result, namely that black is the most attractive color to mosquitoes, followed by blue, brown and red. the least attractive colors seem to be green, yellow and white. Depending on the species, this order can differ a little bit, but black is always the most attractive color. Blue also consistently scores high.  More d... more

*chortling with merriment* Hi Stickman! Actually, I was referring to longer-term than immediate "human recycling" - :D My curiosity goes to recycling within the earth specifically, and I am not specifically a scientific mind, if that makes sense. My question is related to rotting naturally or being cremated - and which is more "useful" to the earth. From the standpoint of, say, the dinos... more

Genetics. In human DNA, gender is determined by two chromosomes. These two chromosomes usually are either classified as "X" or "Y." A girl ("Biological Female") has two "X" chromosomes. Noted as XX. A boy ("Biological Male") has one "X" and one "Y" chromosomes. Noted as XY. "X" and "Y" literally refer to the shape of the chromosome. So girls have some extra genetic material boys don't have. This e... more

Remember that for a trait to be passed on, it doesn't have to be beneficial. It can be "not un-beneficial." That is, if it doesn't stop them from spreading their genes, the trait is carried on. If a homosexual man is married and has kids but decides when he's 40 that he's been homosexual his entire life, it's an evolutionary moot point. He's already had kids and passed on his DNA. And since homose... more
