Biologists are a long way from understanding the entire genome, but as they get to know its parts better, they're getting a more precise comprehension of one of the most important features of evolution: how complex organs evolve. The notion that something as intricate as an eye could have evolved, Darwin wrote, "seems, I freely confess, absurd in the highest degree." But he argued that new complex organs could evolve through a series of intermediate forms...
Paleontologists can track some of life's transformations in fossils - observing how fins gradually evolved into feet, for example. But fins and feet and other complex structures are also encoded in DNA, and until the 1980s, biologists had almost no knowledge of the genes that built them. Over the past 25 years, biologists have identified many of the genes that help build embryos. A number of them help lay out the embryo's blueprint by letting cells know where they are. The cells absorb proteins floating around them, and the signals trigger the cells to make other proteins, which...
...course of human evolution in Africa from apelike ancestors over the past 7 million years Natural selection is a powerful force driving evolution Natural selection's fingerprints can be detected in the human genome. But many mutations have spread thanks to pure chance (a process known as genetic drift) Complex traits like eyes can evolve through a series of intermediate steps Fossils have documented some of those steps in structures such as limbs and ears. Studies on DNA have shown how genes for building old organs have been "borrowed" to help build new ones...
...questions were not scored based on psychological science, the algorithm is effective in pairing compatible students. To match participants, members of the Harvard Computer Society score each question based on personality traits. The results are then run through a secret computer algorithm. “We use a very complex and mysterious algorithm that no one really knows anything about,” HCS Vice President of Communications Hanzi Zhang ’12, said. Datamatch 2009 marks the service’s 16th continuous year of operation. This year, HCS has launched new features that allow users to change...
...Such cringe-inducing moments are not rare in the movie; however, unlike the typical chick flick, the film uses these episodes to translate genuine sentiment. Despite the ever-present threat of takeover by cliché, the film goes beyond one-dimensional characters and scenarios and into surprisingly complex psychological territory. Based on the book of the same name by Greg Behrendt and Liz Tuccillo, “He’s Just Not That Into You” is both a close adaptation and wide interpretation of its original text. At its start, the film stays faithful to the book...
