Losing their tails provided our ape ancestors with an evolutionary advantage, but we're still paying the price by Laurence D. Hurst, PhysOrg, The Conversation, March 3, 2024 The open access paper is: Xia, B., Zhang, W., Zhao, G., Zhang, X., Bai, J., Brosh, R., Wudzinska, A., Huang, E., Ashe, H., Ellis, G. and Pour, M., 2024. On the genetic basis of tail-loss evolution in humans and apes. Nature, 626(8001), pp.1042-1048. Yours, Paul H.- 1 reply

Rarity of Plate Tectonics as an Explanation for Missing Extraterrestrial Civilizations
Oxytropidoceras posted a topic in Fossil News
The Key Role of Plate Tectonics for Accelerating the Evolution of Complex Life: Quest for the Missing Extraterrestrial Civilizations by Taras Gerya and Robert Stern, EGU 2023 #EGU23 PC3 Humans, hominoids and extraterrestials Time interval in video: 2:00 - 7:20 Basic premises: 1. Civilizations can only be expected on planets with oceans, continents, and plate tectonics 2. Such planets most likely form a very small (<<1 percent) of habitable planets with primitive life Co-Evolution of Life and Plate Tectonics #gsa2021 #utdgss Another lecture that touches on this is "Segmentation of subducting slabs and its implication for the onset of modern plate tectonics" by Dr. Taras Gerya." It will eventually be posted to "Virtual Seminar in Precambrian Geology" Yours, Paul H.- 1 reply

Apes' inner ears could hide clues to evolutionary history of hominoids
msantix posted a topic in Fossil News
A study looked at the morphology of the inner ears of living and extinct hominoids (living hominoids includes humans, chimpanzees, orangutans, gorillas etc). Using a 3D imaging technique, the team were able to capture the complex shape of the inner ear cavities among 27 species of monkeys and apes including humans, the extinct ape Oreopithecus & the fossil hominim Australopithecus. The findings showed that the shape of these structures reflected the relationship between the species and not how they moved. The findings confirmed that the inner ear of Australopithecus resembled like that in modern humans than other apes, supporting the consistent view of a close evolutionary relationship between Australopithecus and modern humans and that Oreopithecus was a much older species of ape somewhat related to other modern apes. eLife.
