Researchers found that the green-flowered Aeschynanthus acuminatus evolved on the mainland, not in Taiwan, and adapted to shorter-beaked birds. This contradicts the Grant-Stebbins model of plant evolution, which predicted the species would evolve in Taiwan with new pollinators.
A new organism, Solarion arienae, and its unique predatory structure have been discovered, providing insight into the earliest stages of complex life. The research team identified ancient mitochondrial pathways and established a new phylum, Caelestes, reshaping our understanding of eukaryotic evolution.
A study comparing two species of transparent worms reveals that gene expression patterns tend to remain unchanged in basic cell types, while diverging more rapidly in specialized cells involved in sensing and responding to the environment. The findings provide new insights into the pace of evolution in organisms.
Researchers establish culture of persistent flagellated protist from seawater, challenging current understanding that Endomyxa lack flagella. The discovery offers insights into evolutionary history and biological diversity of Endomyxa.
The discovery of a 355-million-year-old sandstone slab in Australia reveals the earliest clawed footprints ever found, challenging the long-held timeline of tetrapod evolution. The findings suggest that reptiles evolved significantly earlier than previously thought, impacting the entire evolutionary history of amniotes.
Two proteins, viperins and argonautes, play important roles in human immunity, originating from Asgard archaea. These defense systems have been passed down for billions of years, providing a crucial line of defense against viruses.
Researchers analyzed genomes of 363 bird species and found significant variations in cryptochrome 4 gene, indicating adaptation to environmental conditions. This specialization could be related to magnetoreception in migratory birds.
Researchers identified 10 new types of DNA polymerase involved in mitochondrial DNA maintenance, including rdxPolA, which is a direct descendant of the α-proteobacterial symbiont that gave rise to the first mitochondrion. The study provides critical insights into the early evolution of mitochondrial DNA maintenance machinery.
Researchers isolated and described novel yeast species from the gut of green lacewings in Japan, revealing a wider range of microbial inhabitants than previously known. The study identified three new species within the Metschnikowia genus, shedding light on the insect microbiome's complexity.
Researchers have discovered that eukaryotes, including plants, animals, and fungi, share a common ancestor among the Asgards. The team identified a newly described order called the Hodarchaeales as the closest microbial relative to all complex life forms on the tree of life.
A new parasitic euglenid species has been discovered within four animal species collected from a Japanese rice field. The flagellate displayed active metaboly without flagella inside the host body, but extended its flagella upon leaving the host to swim.
A study by the American Museum of Natural History and collaborators classifies the world's simplest animals, placozoans, using genetic makeup, revealing distinct lineages and relationships to cnidarians and bilaterians. The research establishes a backbone taxonomy for the phylum, providing insight into their evolution and diversity.
Scientists from OIST and colleagues reveal that Kamptozoa and Bryozoa belong together, contrary to previous studies. Using high-quality sequencing technology, they found the two phyla split from mollusks and worms earlier than thought, forming a distinct group.
A new bacterial strain, Noda2021, belonging to Candidatus phylum Dependentiae has been isolated and sequenced, revealing its genetic material and potential ecological significance. This discovery sheds light on the diversity of microorganisms in Japan's microbiological hotspots.
