Sceince evolution

Science Evolution and Creationism Biological evolution is the central organizing principle of modern biology. The study of biological evolution has transformed our understanding of life on this planet. Evolution provides a scientific explanation for why there are so many different kinds of organisms on Earth and how all organisms on this planet are part of an evolutionary lineage. It demonstrates why some organisms that look quite different are in fact related, while other organisms that may look similar are only distantly related. It accounts for the appearance of humans on Earth and reveals our species’ biological connections with other living things. It details how different groups of humans are related to each other and how we acquired many of our traits. It enables the development of effective new ways to protect ourselves against constantly evolving bacteria and viruses.

Biological evolution

For more than a century and a half, scientists have been gathering evidence that expands our understanding of both the fact and the processes of biological evolution. They are investigating how evolution has occurred and is continuing to occur. In 2004, for example, a team of researchers made a remarkable discovery. On an island in far northern Canada, they found a four-foot-long fossil with features intermediate between those of a fish and a four-legged animal. It had gills, scales, and fins, and it probably spent most of its life in the water. But it also had lungs, a flexible neck, and a sturdy fin skeleton that could support its body in very shallow water or on land. Earlier scientific discoveries of fossilized plants and animals had already revealed a considerable amount about the environment in which this creature lived. About 375 million years ago, what is now Ellesmere Island in Nunavut Territory, Canada, was part of a broad plain crossed by many meandering streams. Trees, fern

Newton's theory

Does this mean that Newton's theory of gravity is now wrong? Well, yes, ... but it was mostly correct. In fact, Newton's theory correctly describes how gravity will behave in our everyday world. It just wasn't a complete theory ... it didn't explain black holes. Another example of a theory that is not perfect, but is mostly correct, is the simple set of equations that detemine how fast something is moving. To find an object's speed, you divide the distance travelled by the time it took. For example, if it is 80 km to the nearest town, and it takes you 1 hour to get there, your average speed was 80 km/h. This is so obvious, that most people would consider it to be universally true. But of course it's not. It's only an incomplete description of how things move. It's almost totally correct. What it does not explain properly is motion that is very fast ... at speeds approaching the speed of light. A better theory by Albert Einstein, which accepted all of the

Flat Earth

Science works according to certain rules. One of them is that when a scientist has a new idea that he thinks is right, he publishes his results so scientists all around the world can check his results. If their experiments agree with his, his theory will be accepted as correct. But it doesn't stop there. Other scientists will take the theory and build on it, attempting to explain the way our world works. Eventually the theory will be the basis of many other theories, and all of them may accurately describe, predict, or explain the way things work. But, surprisingly, this does not necessarily mean that the original theory was 'correct'! It all depends what you mean by 'correct'. For example, a long time ago, most people believed the theory that the earth was flat. This is obviously an incorrect theory. Then a new theory came along. This new theory stated that the earth was a sphere. Most people believe this theory ... you probably do too. But it's not a correct t

For the third consecutive year, nine students from the Preuss School at UCSD, a charter school that provides rigorous college prep for low income students, came to Sanford-Burnham to put on their lab coats and safety goggles and learn about biomedical research by doing it. The weeklong internships, sponsored by philanthropists Peter Preuss and Wain Fishburn, took these students to four labs, where they investigated aging, rare bone diseases, programmed cell death and drug discovery. At the end of the week, the students presented their research at a luncheon in their honor. For the students, who are all entering their junior year, the time spent in Sanford-Burnham labs has provided new information to help guide them to a career path. “This is a great opportunity to see behind the scenes,” said Mustafa Malik, “to have a close-up opportunity to view the science and the technology.” Sharon Vongvanith echoed this sentiment. “I’ve always wanted to be an obstetrician, and I wasn’t really sure

Natural Sciences deal with matter

Do you feel at peace by a mirror-still lake at dusk? Does the honking of a v-line of geese over a frozen lake put wings on your soul? Does a brilliant sunrise or the sight of the Space Shuttle leaving its earth-pad inspire your heart with hope and energize your spirit? Then a visit through the natural sciences is a hobby you might enjoy and one which may enrich you and help build your understanding of Nature in your life. The Natural Sciences deal with matter, energy and measurable phenomena in the natural world, unlike the applied sciences such as Engineering or Architecture, or the formal studies that include mathematics and Computer Science. In ancient times, Plato and his followers studied Nature and labeled it natural philosophy. As modern times approached, scholars renamed the the field natural science, applying inductive reasoning which is the scientific method that prevails today. Though there is some discussion and difference of opinion as to the exact boundary of the natural

Applying Natural Makeup

Natural Makeup Natural makeup is a term used to describe makeup that mimics tones and hues already within one's complexion. A complexion consists of many hues and undertones. The ultimate goal of applying natural makeup is to create harmony with what nature has provided. Often times, natural makeup is confused with no makeup. No makeup just implies a lack of effort and time; natural makeup is actually, just the opposite. It is carefully selected and applied to enhance features so that they appear to have been a genetic gift of beauty. This is not to suggest that natural makeup means spending an outstanding amount of time applying and outstanding amount of makeup. It just means spending quality time applying makeup strategically. Let me explain. To Begin Natural Makeup 1. Always begin with a cleansed, toned, and moisturized face and eye area. Being of mature skin, I use an alpha hydroxy serum for gentle exfoliation and promotion of smoother skin. The serum will help rid the skin of
