Is genetic evolution predictable?
Ever since the integration of Mendelian genetics into evolutionary biology in the early 20th century, evolutionary geneticists have for the most part treated genes and mutations as generic entities. However, recent observations indicate that all genes are not equal in the eyes of evolution. Evolutionarily relevant mutations tend to accumulate in hotspot genes and at specific positions within ge...
متن کاملEvolution: Welcome to Symbiont Prison
Can egalitarian partnerships exist in nature? A new study demonstrates how protist hosts use and abuse their algal symbionts depending on their needs. While this relationship allows protists to survive in low nutrient conditions, it leaves little room for algal retaliation.
متن کاملThe evolution of host-symbiont dependence
Organisms across the tree of life form symbiotic partnerships with microbes for metabolism, protection and resources. While some hosts evolve extreme dependence on their symbionts, others maintain facultative associations. Explaining this variation is fundamental to understanding when symbiosis can lead to new higher-level individuals, such as during the evolution of the eukaryotic cell. Here w...
متن کاملPredictable bad evolution of an acute pancreatitis.
We present a 60-year-old woman with a previous cholecystectomy, operated of a parahiatal hernia in 2008 and reoperated with a Nissen funduplicature because of its reappearance in 2010. Ten months after this last intervention, the patient went to the emergency department because of sudden abdominal pain. The pain radiated from the epigastrium to both iliac quadrants and her back. In the physical...
متن کاملThe loci of evolution: how predictable is genetic evolution?
Is genetic evolution predictable? Evolutionary developmental biologists have argued that, at least for morphological traits, the answer is a resounding yes. Most mutations causing morphological variation are expected to reside in the cis-regulatory, rather than the coding, regions of developmental genes. This "cis-regulatory hypothesis" has recently come under attack. In this review, we first d...
