Female guppies used in the experiment were the offspring of initial generation descendents of seafood collected in 2008 from a downstream, high predation site on the Aripo River in the Northern Range Mountains of Trinidad.. Adults compensate for poor early begin through adaptive changes Does the environment encountered early in existence have long term and predictable long-term results in adulthood? Such effects have been reported in numerous organisms, including humans. But a biology graduate pupil at the University of California now, Riverside reviews that how individuals fare as adults isn’t just a passive consequence of the limits that early conditions may impose on them. Learning how adult Trinidadian guppies responded to their early food circumstances, Sonya Auer found that the guppies had compensated for a poor start to life in unpredicted, and adaptive potentially, ways.2 in the journal Neurology, hint at one reason why people who have type 2 diabetes have an increased threat of Alzheimer’s disease. That is, type 2 diabetes could cause human brain abnormalities that pile on to various other degenerative changes that eventually lead to dementia, explained study senior researcher Dr. Velandai Srikanth, a geriatrician at Monash University in Melbourne, Australia. However, he said, this study shows only a correlation between type 2 diabetes and mind tangles. It’s not clear whether the type 2 diabetes is the cause, since there are various other things to consider. Obesity is one of these, Srikanth said.
