Blond hair color is more frequent in Europe than in any other part of the world. The estimated date of the genetic mutation that resulted in “blond” hair color was about 11‚000 years ago during the last ice age. A typical explanation for the evolution of blond hair was the people of Northern Europe’s vitamin D absorption and synthesis. As Europeans were subjected to a seasonal deficiency of sunlight‚ which is required for vitamin D synthesis‚ they developed an adaptation for lighter skin. Light

The Evolution of Compassion The evolution of compassion as a part of human nature has been a long standing debate topic. It is typically ignored when analyzing our evolutionary process‚ and if considered is viewed as some sort of emotional unreliability‚ and something that hinders out ability to evolve. However‚ compassion is an innate part of human nature that has evolved from thousands of years of survival. There are three evolutionary arguments for compassion. The first is that within the

Gertsen Skin Evolution Essay Human skin pigmentation is the product of two clines produced by natural selection to adjust levels of constitutive pigmentation to levels of UV radiation (UVR). One cline was generated by high UVR near the equator and led to the evolution of dark‚ photo protective‚ melanin-rich pigmentation. The other was produced by the requirement for UVB photons to sustain cutaneous photosynthesis of vitamin D3 in low-UVB environments‚ and resulted in the evolution of pigmented skin

The focus is to inform the readers that "smoke weed everyday" or "finding Molly" getting women is not what the hip-hop scene is all about. Hip-hop artists tell stories‚ or teach listeners about the

Divergent Evolution Evolution is the theory of organisms changing over time. The first two people to explore this theory were Charles Darwin and Alfred Russell Wallace. There are four types of evolution‚ those being adaptive‚ convergent‚ divergent‚ and co-evolution. Divergent evolution is when two or more animals originate from a common genetic base. To prove divergent evolution in animals‚ the Ursus Maritimus or polar bear is an example. Divergent evolution is when similar animals branch off

building remains standing. Architects need to design structures that hold up under any combination of three physical forces; compression‚ tension‚ and bending. To days architects have a plethora of materials at their disposal‚ they benefit from the evolution of materials and have the opportunity to use them how they wish‚ but it has not always been this way. Primitive buildings were built using dry masonry‚ which is a simple technique of stacking stones in a consistent pattern without using any mortar

THE EVOLUTION OF A COPY PROGRAM BY PANKAJ KAMTHAN 1. INTRODUCTION This document tells a ‘story’ of the evolution of a program caused by the unforeseen changes in the requirements [Martin‚ 2002; Martin‚ Martin‚ 2006]. Let I be the set of input devices‚ O be the set of output devices‚ and let P be the program. Then the story is about the impact on the design of P due to variations in | I | and | O |‚ where | · | denotes the cardinality. The moral of the story is that‚ unless there is adequate

the new anglerfish species. I’m pleased you’ve taken an interest‚ but I don’t think you understand some of the concepts you brought up. So I want to help you understand how evolution works‚ and better understand how creatures like the Lasiognathus dinema evolved. I first want to address Charles Darwin’s concept on evolution. You stated that only the strongest and most important species survive. While strength is an important variable in survival‚ an organism’s fitness is not related to always related

which is through their butts. This whole butt breathing adaptation is part of the aquatic turtles’ evolution. Apart from breathing through their butts there are two other ways turtles can breathe. The first way is the one most used among all creatures: through their lungs. Like most vertebrates‚ turtles use their lungs as the main method through which they respire; however‚ through years of evolution turtles have flattened out the whole underside of their shells so that it creates a barrier for their
