I REQUEST HELP. When I was a kid in the 90's to early 00's, I remember seeing a museum exhibit showing how horses were once believed to evolve from very small horses to modern day horses in order of gradually increasing size. It explained that when carbon dating was discovered, however, the remains were dated, revealing that horses have gone up and down in size throughout history/prehistory. Does anyone have any resources about this? #biology #evolution #EvolutionaryBiology #horses #prehistory

Cochliomyia hominivorax (the New World screwworm) is an obligate parasitic blowfly whose larvae require living tissue from a warm-blooded host to complete their developmental cycle, resulting in a severe, rapidly destructive condition known as myiasis.

Researchers have identified a direct link between intestinal obstruction and behavior in Drosophila melanogaster, where the inability to excrete metabolic waste (meconium) prevents independent feeding and induces prolonged sleep.

Rhodoliths are unattached, pebble-like marine nodules formed primarily by calcifying coralline algae that serve as vital habitats and contribute to long-term carbon storage in ocean sediments.

How Neanderthal Genes Influence Today’s Sensitivity

Peter Dazeley//Getty Images Some people flinch at a needle prick faster than others. One possible reason, at least in a very specific experimental setting, may be old very old DNA. In a 2023 paper published in Communications Biology, researchers linked three Neanderthal-derived variants in the gene SCN9A to a lower threshold for one kind of pain test in modern humans: a skin-pricking test performed after the area had been sensitized with mustard oil.......Continue reading....

Dolichol is a vital lipid required for protein glycosylation, a process essential for protein function across all eukaryotic life. Recent research confirms that the three-step "detour" pathway for its biosynthesis is not exclusive to humans but is an evolutionarily conserved mechanism found in organisms as simple as budding yeast.

Following the asteroid impact 66 million years ago, select marine organisms survived the mass extinction due to specific biological advantages. A recent trait-based numerical model reveals that small body size and high tolerance to darkness were the primary attributes enabling the survival of basal food chain species such as plankton.

Recent paleontological findings from the Xiannüdong Formation in China provide high-fidelity fossil evidence proving that Bryozoa (moss animals) originated during the Cambrian explosion, closing a 20-million-year gap in the fossil record.
