People who transform the history of evolutionary species around the world: Paper – Langley Advance



Narcotics develop smaller, more maneuverable wings to help them avoid buildings and vehicles.

Some fish grow in the mouth, which is a smaller and harder hook.

Large animals from horses to tuna disappear.

At the same time, it's a time for a boom, do not worry about where it lives or what it's eating.

"It's a transformation of the living wood," said Sarah Oto, a researcher at the University of British Columbia, whose paper was published Wednesday by the London Royal Society Proceedings.

Otto, a well-known theoretical biologist, says that human activity and presence have become one of the greatest drivers of evolutionary change around the world.

"Human influence on the world is not only local," she said. "They change the course of evolutionary history for all species on the planet, and this is a notable concept for thinking."

Earth scientists have long debated the idea of ​​anthropocene – the period of Earth's history, determined by the geological markers of human influence. Otto, after completing dozens of research reports, it is concluded that the planet's biology becomes similar, as plants and animals respond to human pressure.

Her paper is full of examples of bird species, slowly forgetting to migrate to mosquito breeds specifically tailored to metro tunnels.

Potatoes have behind-the-scenes changes in the shape and the strength of the house's gills. Different mammals are becoming nights to avoid human conflicts. Introduced species change local plants and animals.

That's a mistake, thinking that evolution needs millennia, Otto said.

"The evolution takes place very quickly when the selection regime is strong. In some years, we can see changes in evolution over the years in plant populations."

If changes take place too quickly, so that development continues, there is always a disappearance.

Sex loss rates are now around 1000 times higher than before human domination. Believes that more than one of the five plant and animal species is at risk.

Disappointments have always happened. But Oto said that they are at such a pace and reacting to similar pressure that they reduce the ability of evolution to react to change.

"We are losing the ability to get back to development."

Force coercion in a human-made box reduces variability, leaving aging work responsive to future change. And the removal of dairy species removes them all forever.

"If we destroy large-scale mammals, even if people disappear on the planet, we will not see the immediate return of ecosystems to ensure the right balance between small, medium and large species," said Otto.

"We abolish opportunities. We abolish opportunities both in species, eliminating variability, and we also abolish the possibilities of living in a tree by cutting species."

The species that works well are the generalizers – crows, koyotes, dandelions.

"Those who can endure and develop in a changed human environment," Oto said. "Pigeons and Rats."

Otto said that the greatest human-induced evolutionary pressure is climate change.

"Our first challenge is to tackle climate change. If we do not do this, we will lose more species."
