Evolution

Most of us don't give much thought to caterpillars, but nature is full of species with incredible creativity. From transparent skin to skull-like masks, these creatures use amazing survival strategies to avoid becoming a meal for birds and insects.

A new study has discovered that dozens of animal species are capable of breaking down PHA, a type of natural plastic produced by bacteria. Researchers estimate that this ability has existed for hundreds of millions of years and may change the understanding of the carbon cycle in nature.

A new study reveals that the evolution of snakes was much more diverse than previously thought: a fossil discovered in Brazil indicates that as early as 80 million years ago, they inhabited different habitats and developed different sensory strategies.

A study led by a researcher from Tel Aviv University offers an evolutionary explanation for the differences in pelvic structure: in the modern male, a spring-like biomechanical mechanism has developed that absorbs shocks, stores energy, and makes long-distance walking more efficient. So why is the situation different for women?

A large-scale international study found that areas of sensitivity to tickling on the human body are identical across different cultures, shattering centuries-old theories. An artificial intelligence model predicted the most ticklish areas with an accuracy of nearly 100%. Researchers: "This is not just a reaction to touch, but an evolutionary mechanism for strengthening social bonds."

A new study from Flinders University in Australia has revealed that the "fecal revolution" about 540 million years ago was a major catalyst for the development of biodiversity and complex ecosystems. By analyzing ancient fossilized feces, the researchers show how digested food created an evolutionary feedback loop that made Earth habitable.
