Earth warming makes lizards smarter

Biologists have determined that high temperatures have a positive effect on the lizard's mind. Global warming makes them smarter. That's the conclusion of a study recently published in the journal Biology Letters.

The object of the study is the lizard species whose scientific name is Bassiana duperreyi . They have a strange property that the authors of the paper published in Current Biology in 2009. It is the sex-size egg size of the lizard that will hatch from there. In this new study, biologists put eggs in incubators and set different temperature regimes: one temperature oven from 8.5 to 23.5 degrees Celsius and one oven, from 14.5 to 29 ,5 ° C.

They then determined the lizards 'wisdom' expanded by placing them in boxes with corridors with two holes so they could crawl out when they ran away. A hole closed with a transparent glass door and an opening hole, from the inside, it looks like there's no difference. They make them afraid to crawl out in the hallway luckily.

After a few attempts, their brain can remember the way it can escape and the road is blocked by the glass, showing memory (and intelligence). As a result, after 16 attempts, 6 out of 9 animals hatched at high temperatures found a way to get out immediately after the second time. While those that hatch at low temperatures have only one having the same ability.

The head of the research group Joshua Amilia concluded: Global warming for Bassiana duperreyi lizards is not a bad thing, but vice versa, making them smarter.

Currently, scientists are focusing on studying the effects of climate change on organisms. For example, atmospheric CO ₂ concentrations increase the acidity of oceans affecting many species such as corals. At the end of 2011, Heredity Magazine published an article where authors discovered global warming that affected the ratio between the number of red ladybirds and black ladybirds living in the Netherlands.
