ANN ARBOR—For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ...
Yet modern biology has revealed that cells are preternaturally sophisticated assemblages — literally automated, miniaturized factories. How could the evidence have been overwhelming but now orthodoxy ...
The theory asserts that the majority of genetic variations within a species are neutral, meaning that do not positively or negatively impact the organism. It also suggests that the differences between ...
Evolution is a fascinating field but can be rife with misunderstanding. One misconception is that evolution has some innate sense of direction or purpose. In reality, evolution is a mindless, ...
Evolution has produced countless amazing life forms, but you need look no further than to the human body to find examples showing that evolution has also produced a number of poor constructions."The ...

When Charles Darwin articulated his theory of evolution by natural selection in On the Origin of Species in 1859, he focused on adaptations — the changes that enable organisms to survive in new or ...
If you had braved the jungles of China’s Fujian province in the early 20th century, various accounts say, you might have witnessed a stunningly unexpected animal: a blue tiger. These tigers were ...
For more than half a century, many biologists have leaned on the neutral theory of molecular evolution to explain how DNA and proteins change over time. The idea grew from early work in the 1960s, ...
The period preceding the emergence of behaviorally modern humans was characterized by dramatic climatic and environmental variability - it is these pressures, occurring over hundreds of thousands of ...
