国际研究团队通过基因组分析揭示，加拉帕戈斯群岛的巨型雏菊（Scalesia）植物多次独立进化出相似的耐热叶片形状，但每次进化所利用的遗传机制各不相同1。这一发现为平行进化提供了明确证据，表明自然界多次抵达同一解决方案，却通过不同的遗传途径实现1。研究由挪威科技大学、皇家植物园邱园、加州大学戴维斯分校等多家机构合作完成，相关论文已发表于《自然通讯》1。
论文第一作者范妮莎·比克表示："这提供了平行进化的清晰例证：自然多次到达相同解决方案，但通过不同的遗传途径"1。研究还发现，Scalesia属植物的孤立种群之间存在重大遗传差异，暗示新物种可能正在形成过程中1。该属植物所有物种均在过去一百万年内出现1。
An international research team has uncovered compelling evidence of evolution solving the same biological problem multiple times through distinctly different genetic mechanisms in the Galápagos Islands.1 Researchers analyzed the giant daisy plants of the Scalesia genus and found that heat-resistant leaf shapes evolved independently on several occasions, yet each instance employed a different combination of genes.1
The findings, published in Nature Communications in 2026, reveal significant genetic differences among isolated populations of Scalesia, suggesting that new species may be forming.1 All species within the Scalesia genus emerged within the past million years, according to the study.1 Lead author Vanessa Bieker explained the implications: "This provides a clear example of parallel evolution: nature arrives at the same solution multiple times, but through different genetic pathways."1 The research involved collaboration among institutions including the Norwegian University of Science and Technology, the Royal Botanic Gardens Kew, and the University of California, Davis.1
