Lungfishes are a curiosity of nature. Like several modern fish species, lungfishes have lung-like structures in addition to their gills. Macroevolutionists claim that lungfishes represent a transition between sea and land organisms. However, despite their interesting organ, genomically, lungfishes cannot be described as a transitional species. The expression pattern of several genes in their lungs, vomeronasal organs (VNO), and limbs all differ from those in other fish analyzed. Among lungfish genomes, the 43 Gb genome of the Australian lungfish in particular is much larger than that of other known fish. Mitochondrial DNA analysis likely places lungfishes in their own separate apobaramin. Many modern fish are obligate air breathers, yet they are not on the alleged trajectory between sea and land organisms. Therefore, lungfishes are most likely just other species of fish with lungs and not transitional species that likely belong to their own separate kind(s).
