Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny [ 1 ] (the evolution of species). The science began in the classical era , continuing in the early modern period with work by Pierre Belon who noted the similarities of the skeletons ...
Tyson dissected a timber rattlesnake in 1683 and produced one of the earliest and most accurate descriptions of the internal anatomy of snakes. He was the first to describe the loreal pits of the Crotalinae. Tyson however did not recognize its heat-sensing function, thinking it was a hearing organ. [5] [6]
When a new chair of comparative anatomy for the University of Edinburgh was proposed in 1816, Barclay was the leading candidate. However, the proposal was defeated by the concerted opposition of a number of the incumbent medical professors, led by John Hope , Robert Jameson and Alexander Monro, tertius , who feared the new chair would encroach ...
Comparative study of the anatomy of groups of animals or plants reveals that certain structural features are basically similar. For example, the basic structure of all flowers consists of sepals , petals , stigma, style and ovary ; yet the size, colour , number of parts and specific structure are different for each individual species.
While recognizing the importance of comparative embryology in the study of descent, Gegenbaur laid stress on the higher value of comparative anatomy as the basis of the study of homologies, i.e. of the relations between corresponding parts in different animals, as, for example, the arm of man, with the foreleg of a horse, and with the wing of a ...
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
One of the first to study comparative anatomy, Petrus Camper demonstrated the principle of correlation in all organisms by "metamorphosis". In his 1778 lecture, "On the Points of Similarity between the Human Species, Quadrupeds , Birds, and Fish; with Rules for Drawing, founded on this Similarity," he metamorphosed a horse into a human being ...
