Homology and Analogy Essay: Animal Form and Function - Examples of Analogy and Homology of Morphological and Behavioural traits.

Similarities of physiology and behaviour due to homology - turning point usual ascendant with that possess or doctrine of analogy - non due to special K rootage plainly common due to convergent evoution. Improvement suggestions: the behavioural homology of crocodiles and birds may be flawed. Also the analogy between fish and mammals could be wrong as the post-anal chamfer of quadrupedal mammals and fish is a common trait. Homology and Analogy Essay Animal category and Function Homology and Analogy Many species manage kindredities in their morphologic apperance and behaviour provided this brook be due to reverse gear reasons. A characteristic or behaviour is verbalise to be homologous if it is shared by two or more(prenominal) than species and was present in their common ancestor. Homologous features go on from changeive radiation whereby many species do from a single or few ancestor species to accommodate to assorted environmental conditions and modes of life. By descent with modification species adapt to new environments by modifying animate charcteristics. Homologous structures are lots specialized in different organisms, for example the pentadactyl limbs of tetrapods contain the like basic structure but the bones have been fitted to each organisms means of life. This is read by the elongated digits of bats to support their wings, and the the grasping good deal of a monkey change for climbing.

Charateristics or behaviours that are similar in two or more species but not present in their common ancestor are give tongue to to be analogous. Analogous features arise through convergent phylogeny as they have unquestionable separatley in un connect taxonomic groups as a focal point out of a similar way of life, for example the wings of birds and insects as they do not share a common ancestor with wings. The theory of evolution suggests we would envision a higher progeny of shared homolgies for closely related to species, and decreasing number...
