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 feature article or analogy - not due to common ascendent plainly common due to convergent evoution. Improvement suggestions: the behavioral homology of crocodiles and birds whitethorn be flawed. Also the analogy between moderatek and mammals could be wrong as the post-anal tail of quadrupedal mammals and search is a common trait. Homology and Analogy Essay Animal discrepancy and Function Homology and Analogy Many species theatrical role kindredities in their morphological apperance and behaviour further this can be due to opposer reasons. A characteristic or behaviour is verbalise to be homologous if it is shared by two or to a greater extent 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 mo des of life. By descent with modification species adapt to new environments by modifying substantial 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 evince by the elongated digits of bats to support their wings, and the the grasping multitude of a monkey adapted for climbing.

Charateristics or behaviours that are equivalent in two or more species but not present in their common ancestor are express to be analogous. Analogou s features arise through convergent organic! evolution as they have developed separatley in un connect taxonomic groups as a result of a similar counseling 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 see a higher number of shared homolgies for closely related to species, and decreasing number...
