Not exact matches

For example, since skin color has no demonstrable relation to intellectual ability, esthetic sensitivity, or character, it follows that no significant conclusions about a person's characteristically human behavior can be drawn from the nature of his pigmentation.

The combined data allowed the team to find eight sites in the human genome that are particularly associated with the level of skin pigmentation.

Changes to skin pigmentation pathways probably reflect selective pressures related to sunlight exposure that humans experienced as they spread out from humanity's origins in Africa to other parts of the world and adapted to local environments.

Variation in pigmentation among human populations may reflect local adaptation to regional light environments, because dark skin is more photoprotective, whereas pale skin aids the production of vitamin D. Although genes associated with skin pigmentation have been identified in European populations, little is known about the genetic basis of skin pigmentation in Africans.

Despite the wide range of skin pigmentation in humans, little is known about its genetic basis in global populations.

The discovery sheds new light on our understanding of the genetic complexity underpinning variations in human pigmentation, and could advance our knowledge of conditions linked to pigmentation, such as skin, testicular, prostate and ovarian cancers.

Analysis of the genetics of skin pigmentation in Africans informs upon melanocyte biology and the evolution of skin pigmentation in humans.

This study sheds light on the evolutionary history, and adaptive significance, of skin pigmentation in humans.

«We've been trying to track down the genetic and molecular basis of naturally occurring traits — such as hair and skin pigmentation — in fish and humans to get insight into the general principles by which traits evolve,» said David Kingsley, PhD, professor of developmental biology.

We show that both dark and light pigmentation alleles arose before the origin of modern humans and that both light and dark pigmented skin has continued to evolve throughout hominid history.

iSAFE identified identical mutations in multiple non-African populations in 5 regions associated with skin pigmentation, suggesting an early response to the onset of selection as humans migrated out of Africa.

«Our aim with this project was to use this method to demonstrate the feasibility of making 3D in - vitro pigmented human skin constructs, with uniform skin pigmentation.»

A new method for controlling pigmentation in fabricated human skin has been developed by researchers from A * STAR's Singapore Institute of Manufacturing Technology (SIMTech) and the Singapore Centre for 3D Printing (SC3DP) at Nanyang Technological University.

In their paper, publishing today in Biofabrication, the team show how they utilise 3D bioprinting to control the distribution of melanin - producing skin cells (melanocytes) on a biomimetic tissue substrate, to produce human - like skin pigmentation.

Those markers can tell the story of human adaptation as early man moved from equatorial Africa into lower - light regions, and may explain changes in skin pigmentation to metabolize more sunlight, or how indoor living has silently damaged human health.

Scientists at deCODE genetics and colleagues in Iceland and Holland today report the discovery of variations in the human genome that influence pigmentation of hair, eyes and skin.

Approximately 15 genes have been directly associated with skin pigmentation variation in humans, leading to its characterization as a relatively simple trait.

By considering diverse, under - studied African populations, we show how the architecture of skin pigmentation can vary across humans subject to different local evolutionary pressures.

Indeed, a likely reason that melanin pigmentation devolved was to permit humans who migrated north and south of the equator to make enough vitamin D in their skin to satisfy their requirement (96).

Albino dogs as well as humans are predisposed to a variety of skin problems due to total lack of skin pigmentation.
