WebJan 27, 2014 · They call them ‘homologies’ or ‘homologous organs’ or ‘homologous structures’. Homologies simply refer to similarities which, according to evolutionists, are due to their being inherited from a common ancestor. So, according to evolutionists, the eyes of the different animals on the bottom row of fig. 1 are ‘homologous organs ... WebThe Theory. The central idea of biological evolution is that all life on earth shares a common ancestry and some similarities have evolved in other ways. These are called homologies and analogies. We will look at the different characteristics and identify the homologous and analogous organs in the plants and animals we have selected.

WebDeep homology is part of a much wider range of phenomena in which biological (genes, regulatory mechanisms, morphological traits) and phylogenetic levels of homology can both be disassociated. Therefore, to understand homology, precise, comparative, independent statements of both biological and phylogenetic levels of homology are necessary. WebHere are a couple of other supplementary points about "homology": The idea was originally borrowed from biology. "Homology" in biology refers to similarity shared by organismal structures. A common ancestor is assumed in evolutionary biology between homologous structures. The Wikipedia page on biological homology has some interesting exmaples:

WebThe two genes produced by duplication are very similar in how they are expressed within a plant. In the early 1980s, studies of fruit flies led to the discovery of the master-switch genes involved in animal development. Which of these genes are essential for the development of different body segments of fruit flies? Hox Genes
