The issues are "too important to be left to the scientists" (13). After reading his comprehensive book on the history and promise of genetic engineering, Cobb's point is well taken. Humans are human, after all.Carolyn Riley,ChapmanThe Journal of medical humanities...
Even so, the bioethical debate on enhancement, whether it is pharmacological means of improving cognition and morality or genetic engineering to create smarter people or other possibilities, is consistently centred on technologies that do not yet exist. The investigation is divided into three main ...
Until now, Nature’s scoops had been mostly in physics — the discovery of electrons, radioactivity, isotopes, X-rays — but here was an author contending that humans had originated in Africa, “thus vindicating the Darwinian claim that Africa would prove to be the cradle of mankind”. Many...
The current Y chromosome evidence suggests multiple early migrations of modern humans from Africa via Southeast Asia to East Asia. After the initial settlements, the northward migrations during the Paleolithic Age shaped the genetic structure in East Asia. Subsequently, recent admixtures between Central ...
Genetic continuity across transitions in pottery styles reveals that cultural changes during the Ceramic Age were not driven by migration of genetically differentiated groups from the mainland, but instead reflected interactions within an interconnected Caribbean world1,8. This is a preview of subscription...
1980s: Researchers develop the more precise and controllable methods of genetic engineering to create plants with desirable traits. 1990s: The first GMOs are introduced into the marketplace. When Were GMOs Introduced? 1995: Soy Beans 1995: Squash 1996: Corn 1996: Cotton 1997: Papaya 1999: Canola...
The RNA-guided nucleases from CRISPR-Cas systems are currently regarded as the most reliable tools for genome editing and engineering. The first hint of their existence came in 1987, when an unusual repetitive DNA sequence, which subsequently was defined as a CRISPR, was discovered in the ...

of Neanderthal and modern human ancestors occurred 270,000–440,000 years ago. It also showed that Neanderthals shared more genetic variants with present-day humans in Eurasia than with present-day humans in sub-Saharan Africa, indicating that gene flow from Neanderthals into the ancestors of non...
Genetic, linguistic and cultural evidence points to the Roma having originated in North-Western India ~ 1,500 years ago (ya) from a low number of proto-Roma founders3,4,5. These founders started a diaspora through West Asia, and arrived for the first time in the European continent at...
