Taxonomy Genetic Barcoding Biodiversity Evolution Conservation Conservation Biology
By: Nathan Brouwer
High-tech DNA techniques such as polymerase chain reaction (PCR), DNA sequencing, and micro-arrays have revolutionized all aspects of biology. My genetics professor as an undergrad, a traditional bristle-counting fruit fly geneticist, predicted that molecular genetic techniques would spark are theoretical and technical revolution in biology...
Evolution Natural Selection
By: Joanne Smedley
The problem here is the question. Evolution has two meanings in our current society: Evolution natural selection, and Evolution theory of "molecules to man" (to steal a phrase from Ken Ham). People use both interchangeably without really understanding the fundamental difference between them.Natural selection...
How photosynthesis works
By: Wilhelm Schnotz
Photosynthesis: A process essential for life on earthPhotosynthesis is the most essential biological process for human and animal life. It is the process by which carbon dioxide and water are converted by plants and sunlight into the oxygen we breathe and the organic molecules (like...

Should men be allowed to be pregnant and conceive babies? Current technology does not allow for men to conceive, carry, or birth a human child. If technology were available to allow men to conceive and give birth to children should it be allowed? Mankind's morality...
Functions of membrane proteins
By: Debbie Luyo
Biological membranes encircle eukaryotic cells and their components, or organelles. Membranes allow selective permeability to the cell or organelle, and prevent spontaneous diffusion of water and other molecules. Thanks to the surrounding membrane, idyllic conditions, such as pH and ionic strength, can be maintained within...
Overview of Dugesia
By: Izabella Cecelia
AbstractTaxis is the orientation toward or away from a stimulus. Planaria, in their natural habitat, are known to exhibit positive geotaxis and negative phototaxis. This experiment was conducted with nine different planaria which were observed in the amount of time spent in each condition. In...
How an ant can carry something bigger than itself
By: Linda C. Turman
First of all, I'd like to say that I hate ants. They are a pest and when out of control, they are all over the place. Hard to get rid of, for one. Then one needs to buy something to kill them with. They are...
The Human Race is Devolving
By: J. Merrill
The human race is clearly devolving overall as a species. Although technology allows more access to information and our culture drives our IQ's through the roof compared to our ancient bretheren, it is only the technology that has brought us there.Although technology outpaces this...
The primordial soup theory
By: Janet Grischy
How did life begin? To many thoughtful people that's a highly charged question which inspires vexing debate. To others, the answer is perfectly simple. Life began in the primordial soup.In 1953, at the University of Chicago, Stanley L. Miller, then a graduate student, with...
Is evolution an outdated theory?
By: Randy Crum
Of course evolution is not an outdated theory! We continuously get more and more confirmation of the validity of the hypothesis that all life on Earth shares a common ancestor. Evolution is supported by evidence from the sciences of genetics, biology, paleontology, biogeography, anatomy, comparative...
