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 - divide common ascendant with that bluster or analogy - not due to common antecedent plainly common due to convergent evoution. Improvement suggestions: the behavioural homology of crocodiles and birds whitethorn be flawed. Also the analogy between search and mammals could be wrong as the post-anal tail of quadrupedal mammals and search is a common trait. Homology and Analogy Essay Animal word form and Function Homology and Analogy Many species division kindredities in their geomorphological apperance and behaviour merely this can be due to antonym reasons. A characteristic or behaviour is verbalise to be homologous if it is shared by two or much than species and was present in their common ancestor. Homologous features arise from adaptational radiation whereby many species derive from a single or few ancestor species to adapt to variant environmental conditions and modes of life. By descent with mod ification species adapt to new environments by modifying actual charcteristics. Homologous structures are often specialized in different organisms, for example the pentadactyl limbs of tetrapods contain the same basic structure but the bones have been adapted to each organisms means of life. This is read by the elongated digits of bats to support their wings, and the the grasping bargain of a monkey adapted for climbing.

Charateristics or behaviours that are homogeneous in two or more species but not present in their common ancestor are give tongue to to be analogous. Analogous features arise through convergen t phylogenesis as they have developed separ! atley in un connect taxonomical groups as a result of a similar air 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 keep an eye on a higher number of shared homolgies for closely relate species, and decreasing number...
