As early as the cold worm
On November 8, local time, US "Cell" published group sub-magazine "Contemporary Biology" published online research papers in Zhang Xiguang, Yang Jie, ancient Biology, Yunnan University.
The study confirmed the residence behavior of the dragonfly in the first time, and this behavior pattern has been known to the earliest fossil record, expanding people’s awareness of the Hanwu Community Ecology. Living behavior refers to occupancy and lives in other biological housings, which can occur in different animal groups, including whale-known home crabs, original crustaceous animals, and Fuxi subsequins and 倭倭 囊星.
Most of them are biased towards the ventricle shell, and some will also live in a tube or aperture shell constructed in a polyprope.
"Hanluo Big Broad Dream" is marked from the rapid and diversity of major animal groups.
The increased ecosystem complexity is considered to accelerate this evolutionary radiation.
But even in a specific embedded Boolean shale type bio group, direct evidence about the ecological model of the cold arms group is still extremely rare.
At the upper part of Kunming Lu, the fourth level of the fourth order of the Han Wuliang, the research team collected 4 worm worms with a large ancient oil of Guanshan biotriqué, and the rear of each body was hidden in a soft In the tongue spiral shell, and the diameter of the insect is slightly smaller than the soft tongue pitch, indicating that this worm has selected a soft tongue and "hidden", to avoid the predator. "The residential behavior is widely existed in the modern ecosology department, but the earliest fossil records have traced back to approximately 2 billion years ago, with the time consistent with the ‘born ocean revolution’, while the latter is characterized by high strength prey. "Zhang Xi Guang introduced that residential life habits appeared in the early 190 million years ago, along with the relationship between Hanwu Yi Mid-term organisms such as Demideration, stealing parasitic and end-born students in recent years, indicating early complex ecology The system may be more modern than the past, that is, "Hanwu Big Broad Dream" may be a distinctive feature of the ecosystem increasing in rapid complication and predation intensity.
