Analysis finds defects in the “Protura sister” hypothesis: reassessment of early hexapole lines
Embryology and morphology cannot establish the “Protura sister” hypothesis of the early evolution of hexapoders recently proposed by phylogenies. Credit: Makiko Fukui Early lineages of hexagons (widely defined insects) have been debated for a long time. Researchers and collaborators from Tsukuba University have critically investigated the newly proposed phylogenetic hypothesis of the “Protura sisters.” This analysis revealed the underlying flaws…

Team investigates population genetic characteristics of two hybrid crucian carp lines
Central linkage network based on Tf alleles. Credit: Reproduction and Breeding (2024). DOI: 10.1016/j.repbre.2024.07.002 Crucian carp (Carassius auratus) is a common freshwater fish in China, and its farming mainly relies on artificially bred superior varieties. A hybrid strain derived from Carassius cuvieri (♀) × C. auratus red var. (♂) (HFJ) and new homodiploid crucian carp-like lineages derived from carp (♀)…
