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 sport or analogy - not due to common radical plainly common due to convergent evoution. Improvement suggestions: the behavioral homology of crocodiles and birds whitethorn be flawed. Also the analogy between angle and mammals could be wrong as the post-anal tail of quadrupedal mammals and slant is a common trait. Homology and Analogy Essay Animal strain and Function Homology and Analogy Many species component part kindredities in their structural apperance and behaviour scarce this can be due to enemy 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 arise from adaptive radiation whereby many species derive from a single or few ancestor species to adapt to diametrical environmental conditions and modes of life. By descent with mo dification species adapt to new environments by modifying live 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 shew by the elongated digits of bats to support their wings, and the the grasping push-down storage of a monkey adapted for climbing.

Charateristics or behaviours that are interchangeable in two or more species but not present in their common ancestor are verbalize to be analogous. Analogous features arise through convergent evolution as they have developed separatley in un connect taxon omic groups as a result of a similar flair ! 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 inflict a higher number of shared homolgies for closely relate species, and decreasing number...
