Earth and Life: A Four Billion Year Conversation by Andrew H. Knoll. From the world-renowned geobiologist and bestselling author of A Brief History of Earth, the epic story of a planetary conversation four billion years in the making.

Andrew H. Knoll's Earth and Life is the first book to reveal why we need to listen to both voices—the physical & the biological—to understand how we & our planet became possible.

Ancient chemical evidence points to sea sponges as Earth's first animals A study from the Massachusetts Institute of Technology (MIT) has uncovered chemical evidence suggesting that the first animals on Earth were likely ancient sea sponges. The team found molecular traces, called steranes, in rocks that are over 541 million years old. These compounds match those produced by modern demosponges, a major group of sea sponges. The research strengthens the idea that these early sponges existed long before other animal groups began to diversify during the Cambrian period. The study builds on previous findings from 2009, which showed similar compounds in Ediacaran rocks, and adds new evidence, including C31 steranes that match those produced by living sponges today. By studying both modern sponges and synthetic lab-made molecules, the researchers confirmed that these ancient chemical markers were biological, not geological in origin. This discovery highlights the significant role sea sponges may have played in the early evolution of animal life. The team plans to extend their research to other ancient rocks to further pinpoint when the first animals emerged.

How the Earth rotation slowed down over billions of years, affected Coriolis forces, the circulation of oceans & nutrients, increased surface oxygenation & photosynthesis, & "may have been a long-term background control on [...] the evolution of animals".

Rob McConnell Interviews - RICHARD BENISHAI - Geobiology Richard Benishai explores the field of geobiology, examining how natural and artificial energies within the Earth can influence human health, behavior, and well-being. His work focuses on the interaction between geological forces, electromagnetic fields, and living systems, including how certain locations may enhance vitality or contribute to stress and illness. By studying Earth energies, sacred sites, and the impact of modern infrastructure on biological systems, Richard brings attention to the often-overlooked relationship between our environment and our physical, emotional, and energetic health. His insights encourage greater awareness of place, balance, and harmony between humans and the planet.

Great to see our perspective in print! Chad, Eva, and I suggest that geological and genomic records support the idea that Earth’s first oxygenated habitats formed on the seafloor, especially in shallow benthic settings along continental shelves

The Evolution and Fossil Record of Parasitism This book highlights and reviews the potential of the fossil record to calibrate the origin and evolution of parasitism, and the techniques to understand the development of parasite-host associations ...

Last Thursday (8/5), it was the 4-year anniversary of the publication of our Topics in #Geobiology volume on The #Evolution and #Fossil Record of #Parasitism: Identification and Macroevolution of Parasites. doi.org/10.1007/978-... with @realhuntley.bsky.social Thanks all contributors #paleobiology

Geobiology: iron, sulfur, heat – and first life The very first cells obtained their energy from geochemical reactions. LMU researchers have now managed to recreate this ancient metabolic process in their laboratory.

Researchers at #LMU, led by William Orsi, simulated ancient hydrothermal systems in the #lab. The archaeon 'Methanocaldococcus jannaschii' grew without added nutrients, using hydrogen from iron-sulfur reactions—possibly mimicking early life on Earth.
