If it ’s not one matter , it ’s another : anew hypothesis float around the scientific communitysuggests that germinate bigger brains and superior mind may have conduce to a dramatically lift risk of cancer in humankind . Thanks , brain .
The theory runs like this . Usually cells expire off in a controlled fashion — promise apoptosis — which allows fresh cadre to replace tired old single . The operation allows previous malfunctioning cells to be destroyed before they go varlet and grow into tumour . But in lodge for our brains to grow fully grown , our bodies have had to discover to extend the life story of cells , hold up caspase-mediated cell death and in turn increase the risk of cancer development .
The novel theme ispublished in PLoS Oneand is n’t just grandiose pedantic posturing . In fact , it ’s bet on up by an depth psychology of the lifecycle of cells from both humans , chimpanzees and macaques . The results point to the fact that human cells undergo apoptosis much more slowly — and are at smashing risk of mutation as a upshot .
Perhaps intelligibly , some academics warn that the theory should be taken with at least a small collar of salinity . “ He has a sound experimental finding , ” explained Todd Preuss of the Yerkes National Primate Research Center in Atlanta , Georgia , to New Scientist . “ What that means in the broader setting is open to debate . ” Part of the job is that there is n’t really any taxonomical data on Crab rates in non - human primates to liken to .
Still , the approximation is being taken seriously by many , and it could go a long way in explaining why Crab is such a serious medical job for human the world over . Let ’s just go for that cancer does n’t wipe us out before our brains are big enough to find a cure . [ PLoS OneviaNew Scientist ]
