Nature全文 PDF西非肺鱼呼吸系统单细胞图谱揭示适应陆地生活的演化变化
A single-cell atlas of West African lungfish respiratory system reveals evolutionary adaptations to terrestrialization
Nature communications · 2023
依据索引收录的作者摘要概括。
Summary based on the indexed author abstract.
主要发现 Key findings
西非肺鱼单细胞图谱识别肺、鳃细胞类型及适应离水生存的表达变化，并发现肺与鳔细胞类型的广泛同源性。
A West African lungfish single-cell atlas identifies respiratory cell types and expression changes associated with survival out of water, together with broad lung–swim-bladder cell-type homology.
结论 Conclusions
呼吸系统的陆地适应兼有保守机制与谱系特有变化，单细胞比较可细化其演化解释。
Respiratory terrestrial adaptations combine conserved and lineage-specific changes that can be resolved through single-cell comparisons.
PNAS全文 PDF肉鳍鱼类在登陆前已演化出行走与跳跃步态的行为证据
Behavioral evidence for the evolution of walking and bounding before terrestriality in sarcopterygian fishes.
PNAS · 2011
依据作者摘要概括。
Inspected PubMed abstract indexed by Europe PMC; archived full text does not imply full-text review.
主要发现 Key findings
非洲肺鱼 Protopterus annectens 能在水下借腹鳍进行交替行走及跳跃式运动，即使腰带较小且由肌肉支撑，也能将身体抬离底质。
African lungfish Protopterus annectens uses its pelvic fins for alternating walking and bounding underwater and can lift its body clear of the substrate despite a small muscularly supported pelvis.
结论 Conclusions
部分四足动物式运动行为可能早于指趾和陆地生活出现，因此解释某些泥盆纪足迹时需保持谨慎。
Some tetrapod-like locomotor behaviors could evolve before digits and terrestrial life; certain Devonian trackway interpretations therefore require caution.
