Briefing: How squid survived Earth’s biggest extinction and took over the oceans
Strategic angle: Scientists have cracked a mystery about squid and cuttlefish evolution through genome analysis.
A recent study published on April 1, 2026, utilizes newly sequenced genomes to analyze the evolutionary trajectory of squid and cuttlefish. This research draws on extensive global datasets to enhance understanding of these marine organisms.
The findings suggest that squid and cuttlefish, known for their advanced cognitive abilities, likely emerged as a response to significant environmental changes following the mass extinction.
This genomic analysis not only elucidates the origins of these intelligent creatures but also has implications for marine biology and evolutionary studies, potentially informing future research on marine ecosystems.
