According to the British Daily Mail, at present, an amber found in Myanmar actually records the war between two ants 100 million years ago, and their crotch still bite together, as if time has stopped. The gums fall on their bodies and completely wrap them up.
The two ants in this amber squat tightly together, recording the "old wars" of two ants during the Cretaceous period 100 million years ago.
Scientists believe that the two ants come from different ant species, and they survived during the dinosaur period when they might compete for food or encounter raids. It is reported that there are other ants preserved in amber, including giant ants, and these ancient evidences provide important clues to the behavior of ancient insect groups.
Ants are a "successful" evolutionary species with organizational and hierarchical levels. The two ants in this amber belong to Krishnatermesyoddha and Gigantotermesrex, one of the largest ant species ever discovered, with a body length of 2.5. In centimeters, the head occupies half of the body and has a scissor-like crotch.
This amber provides important clues to the behavior of ancient ant colonies. Ants have different hierarchical levels, including queens and worker ants. In a piece of amber contains a group of worker ants, it is likely that they are out of the group foraging, or two different groups of workers are fighting. These ancient evidences suggest that early ant species, like modern ants, have similar habits and maintain a certain class hierarchy.
Dr. Phillip Barden, a biologist at the American Museum of Natural History, said that we believe that wingless ant species will not fight or defend the territory from other ant species. But the war of modern ants is always happening. By analyzing this amber 100 million years ago, we found that the behavioral characteristics of ancient ants help to reveal the group and diversity of the earliest ancient ants.
Zoologist Dave Grimaldi said: "From an ecological point of view, advanced mass is one of the most important adaptation characteristics of animals. All ant species are group, they are ubiquitous in There are thousands of ant species in the various terrains of the earth, and perhaps new species that we don't know."
The study, published in the recently published Journal of Contemporary Biology, confirmed the existence of advanced ant colony behavior during the Cretaceous period, earlier than the previous fossil record.
