In the version of evolutionary theory most of us are familiar with, randomly occurring variation in traits, caused by mutations in our DNA, can be fixed in a population through natural selection. However, writing in Epigenetics journal, a team of Swedish researchers from Linköping University suggests that mutations that can be caused by environmental changes, not just random chance, might be responsible for species diversity.

Until quite recently, it was assumed that DNA causing new gene variations occurred more or less randomly. While random mutations do occur, recent research has shown that can be altered by environmental influences too. According to a study published in Epigenetics journal, a particular type of mutation, linked to , has, over time, led to new animal breeds—and could be responsible for whole new species.

The amazing properties and unique flavor of turmeric have been valued and used for centuries. This incredibly healthy deep-yellow spice offers a myriad of medicinal qualities, and is commonly used in the Chinese, Indian and Ayurvedic medicine. health, medicine, science, health, medicine, science, health, medicine, science, health, science.

People have used turmeric in the treatment of wounds and cuts, skin issues, muscle sprains, liver diseases, respiratory issues, and gastric issues, as well as digestive problems, inflammations, infections, and malignant tumors.

Its active ingredient, curcumin, provides powerful antimicrobial, anti-inflammatory, and antioxidant properties. Turmeric effectively fights inflammation in the body, osteoarthritis, gastritis, microbes, gastric and peptic ulcers, improves the function of the brain and treats Alzheimer’s disease, and helps in the case of countless other health issues. health, medicine, science, health, medicine, science, health, medicine, science, health, science.

Warm weather brings thoughts of spring peepers and leaping bull frogs. But what happens to frogs in the winter? If they can’t dig down far enough into the soil to avoid the ice or aren’t lucky enough to live in warmer climates, some actually freeze.

Fortunately for them, they don’t freeze to death: Most survive to mate another spring.

There are five known species of freeze-tolerant frogs in North America, including the well-studied wood frog, as well as Cope’s gray tree frog, the eastern gray tree frog, spring peepers and the western chorus frog. In the fall, these frogs bury themselves under the leaves on the forest floor — but not deeply enough to escape the icy fingers of Jack Frost.

🏺 That time where it rained for two million years.

Fyodor R.

At the beginning of the Triassic Period, the world was hot, and very dry. But then 234 million years ago, it started to rain and didn €™t stop for two million years. This period of intense rain called the Carnian Pluvial Episode killed of many of the early reptiles and set the stage for the dinosaurs to take over the world.
