科学家测序了至今最古老的基因组，结果对马家族树的演化提出了新的见解。古老化石来自一个距今大约56万年到78万年前的雄马腿骨化石，化石掩藏在加拿大北部的冻土之中。测序结果表明，所有活着的马科动物——其中包括马、驴和斑马——在400万到450万年前拥有一个共同祖先，比之前的估计早200万年。此前测序的古老DNA最早距今13万年。论文发表在最新一期的《自然》期刊上。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
