Biological homology
WebSep 4, 2024 · Figure 9.3. 3: Mammals (such as cats and whales) have homologous limb structures - with a different overall look but the same bones. Insects (such as praying mantis and water boatman) also have homologous limbs. Cat legs and praying mantis legs are analogous - looking similar but from different evolutionary lineages. 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:

WebHomology (biology), any characteristic of biological organisms that is derived from a common ancestor. Sequence homology, biological homology between DNA, RNA, or protein sequences. Homologous chromosomes, chromosomes in a biological cell that pair up (synapse) during meiosis. Homologous recombination, genetic recombination in … The word homology, coined in about 1656, is derived from the Greek ὁμόλογος homologos from ὁμός homos "same" and λόγος logos "relation". Similar biological structures or sequences in different taxa are homologous if they are derived from a common ancestor. Homology thus implies divergent evolution. For example, many insects (such as dragonflies) possess two pairs of flying wings
WebBiological Aspects. The structural homology of metacaspases to mammalian caspases has led to the speculation that the protein is involved in programmed cell death in primitive eukaryotes, including fungi. A major player in the yeast apoptosis could be the Mca1 [6]. Hence, it is considered that the function of metacaspases in the programmed cell ...
