Ancient DNA Unravels Pre - historic Family Trees and Social Structures
Scientists have successfully reconstructed the kinship networks of multiple ancient settlements through the genetic analysis of a large number of ancient human DNAs, with the longest network extending up to eight generations. This research has revealed social - structural features such as matrilineal or patrilineal inheritance and the layout of kinship cemeteries. Some individuals have even been traced to relatives thousands of miles away.
Animal Life Discovered at Hydro - thermal Vents of the East Pacific Rise
Scientists from Austria and the Netherlands have discovered animal life in the hydro - thermal vent area at a depth of 2,515 meters on the East Pacific seabed. The discovered species include large tube worms and sea snails. These living organisms are found in the warm, liquid - filled cavities within the rock fractures, indicating a possible connection between the sub - crustal ecosystem and the seabed ecosystem.
"Exploration - 3" Commissioned in Sanya, Boosting Manned Deep - sea Diving to Cover the Entire Sea Area
Xinhua News Agency, Sanya, December 29th – The "Exploration - 3", a multi - functional scientific research vessel independently built by China, arrived at the Nanshan Port Public Scientific Research Wharf in Sanya Yazhou Bay Science and Technology City on December 29th, 2024, and was officially commissioned. This event marks a significant breakthrough in China's deep - sea exploration capabilities.
Carbon Dioxide Has Governed Earth's Climate Change for Nearly 500 Million Years, New Research Unveils Deep - time Climate Evolution Map
Recently, scientists from the United States have reconstructed the curve of Earth's average temperature changes over the past 485 million years. By integrating 150,000 paleoclimate records with model simulations, they found that extreme warming events on Earth are highly correlated with the increase in CO₂ concentration. This research was published in the journal Science.
Scientists Drill Deep into Mantle, Obtain Deepest - ever Mantle Core Sample
An international team of scientists has successfully drilled a 1,268 - meter - long mantle core in the Mid - Atlantic Ridge. This is the deepest mantle sample ever retrieved from the ocean floor, mainly composed of serpentinized peridotite, revealing the long - term reaction records between the mantle and seawater.
