- New Origin Of Life Hypothesis: Did Life Begin Between The (Mica) Sheets?
Life on Earth may have originated as the organic filling in a multilayer sandwich of mica sheets, according to Helen Hansma of the National Science Foundation and the University of California, Santa Barbara. In a presentation at the American Society for Ce ...

- Genes In Conflict
"The conflict between maternal and fetus genes is one of the weirdest ideas in the modern theory of evolution."* According to evolutionary logic, the fetus "wants" to milk the mother for all it can get; the mother "wants" to ...

- Evolution Is Speeding Up, Says Researcher, And We're Becoming More Different
Researchers discovered genetic evidence that human evolution is speeding up – and has not halted or proceeded at a constant rate, as had been thought – indicating that humans on different continents are becoming increasingly different. “We used a new genom ...

- New Gene Loss Studies Show How They Contributed To Natural Selection
While it is well understood that the evolution of new genes leads to adaptations that help species survive, gene loss may also afford a selective advantage. A group of scientists has investigated this less-studied idea, carrying out the first systematic co ...

- Insect Study Questions Standard Eusociality Explanation
The January 2008 issue of BioScience includes an article by biologist Edward O. Wilson that argues for a new perspective on the evolution of advanced social organization in some ants, bees, and wasps (Hymenoptera). Wilson’s article surveys recent evidence ...

- Is Most Of The Human Genome Functional?
I first became interested in genome size because of its tie-ins with important evolutionary questions in which I was (and still am) interested, such as punctuated vs. gradual patterns, levels of selection, and adaptive vs. non-adaptive processes. What I d ...

- Bacterial Genomes And Evolution
The seminar that I give most often when I am invited to speak at other universities begins with a brief introduction to genomes, sets up some comparisons between bacteria and eukaryotes, and then moves into a short overview of bacterial genome size evolut ...
