The Interplay of Ontogeny and Phylogeny at the Transcriptome Level of the Tetrapod Heart
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.The main stages of development during which species‐specific heart anatomy is determined in the ontogeny of representative tetrapods. Transcriptomic similarity is expected earlier in development before heart anatomy diverges. ABSTRACT The tetrapod heart is characterized by three chambers in amphibians and non‐avian reptiles, as opposed to four in birds,
