Homologies - University of California, Berkeley
Homologies. Evolutionary theory predicts that related organisms will share similarities that are derived from common ancestors. Similar characteristics due to relatedness are known as homologies. Homologies can be revealed by comparing the anatomies of different living things, looking at cellular similarities and differences, studying ...
Homology (biology) - Wikipedia
Homologies provide the fundamental basis for all biological classification, although some may be highly counter-intuitive. For example, deep homologies like the pax6 genes that control the development of the eyes of vertebrates and arthropods were unexpected, as the organs are anatomically dissimilar and appeared to have evolved entirely independently.

Homologies and analogies - Understanding Evolution
Homologies and analogies Since a phylogenetic tree is a hypothesis about evolutionary relationships, we want to use characters that are reliable indicators of common ancestry to build that tree. We use homologous characters — characters in different organisms that are similar because they were inherited from a common ancestor that also had ...

Homologia (biologia) – Wikipédia, a enciclopédia livre
Homologia (do grego ομοως, "igualmente" e λοlÄγος, "ciência", "razão")  é o estudo biológico das semelhanças entre estruturas de diferentes organismos que possuem a mesma origem ontogenética e filogenética.Tais estruturas podem ou não ter a mesma função. A homologia tem sido uma forte evidência em favor da Teoria da Evolução, pois ela sugere ancestralidade comum ...

Primer Premier's search algorithm finds optimal PCR, multiplex and SNP genotyping primers with the most accurate melting temperature using the nearest neighbor algorithm. Primers are screened for secondary structures, dimers, hairpins, homologies and physical properties before reporting the best ones for your sequence, in a ranked order.

Homologies of the forelimb among vertebrates, giving evidence for evolution. The bones correspond, although they are adapted to the specific mode of life of the animal. (Some anatomists interpret the digits in the bird's wing as being 1, 2, and 3 rather than 2, 3, and 4.)
