These components of religion are composed of forms and functions but only forms which have structure can be passed across generations in DNA and evolve directly by natural selection. Therefore, in order for a component of religion to evolve by natural selection it has to contain structural design...
At present, whether ES-mediated protein targeting evolved early or late in primary plastids is unclear. We can envision two ‘early’ scenarios. In the first, the cyanobacterial ancestor of primary plastids maintained a phagosomal membrane for some time, and it subsequently was transformed into the...
Researchers at a South Korean university recently found a way to create a DNA-based chip that a personal computer can control to perform calculations,according to a new research paper. The team used 3D printing to fabricate a chip, which can execute Boolean logic, one of the fundamental method...
The right-handed sugars in DNA and RNA and left-handed amino acids are thought to have evolved to work with each other during the early Earth, where single-stranded RNA could have been the first molecules that gave rise to DNA and amino acids. This hypothetical time period around 4 billion...
That’s a move similar to what Texas A & M University researchers have been undertaking for the past five years in a project called Noah’s Ark. Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain ...
Epigenetics is the part of genetics that’s based not on the sequence of genetic building blocks but on small yet characteristic chemical markers on these building blocks. The sequence of building blocks has evolved over a long period of time; we all inherit them from our par...

The long neck, he said, must therefore have evolved as a way for the animal to be able to reach past its own legs when it leans to reach the ground to take a drink of water. (Never very popular, Pincher’s suggestion lasted only as long as it took scientists to find and examine ...

They suggest this small bit of duplicated DNA contains the switch that normally turns on SOX9 in response to SRY. When they introduced this duplication into mice, they found that it boosts SOX9 activity, so the change could allow SOX9 to work without SRY. ...
