Serial homology is a special type of homology, defined by Owen as "representative or repetitive relation in the segments of the same organism." [ 1 ] Ernst Haeckel preferred the term "homotypy" for the same phenomenon.
Ape to Man: Theory of evolution is a dramatised documentary on the scientific community's attempts to find evidence of the missing link [2] between early hominids and anatomically modern humans. [1]
In biology, homology is similarity in anatomical structures or genes between organisms of different taxa due to shared ancestry, regardless of current functional differences. Evolutionary biology explains homologous structures as retained heredity from a common ancestor after having been subjected to adaptive modifications for different ...
Earthworms are a classic example of biological homonymous metamery – the property of repeating body segments with distinct regions. In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions. [1]
Whereas ordinary homology is seen in the pattern of structures such as limb bones of mammals that are evidently related, deep homology can apply to groups of animals that have quite dissimilar anatomy: vertebrates (with endoskeletons made of bone and cartilage) and arthropods (with exoskeletons made of chitin) nevertheless have limbs that are constructed using similar recipes or "algorithms".
Serial passage is an artificial technique that is used in a laboratory setting, rather than a natural process. Accordingly, the likelihood that the H5N1 virus would actually mutate to become transmissible in humans is unknown; however, researcher Derek Smith created an evolutionary model to show that this is possible.
Homology (anthropology), analogy between human beliefs, practices or artifacts owing to genetic or historical connections; Homology (psychology), behavioral characteristics that have common origins in either evolution or development
Thus, the genome sequences can be used to identify gene function, by analyzing their homology (sequence similarity) to genes of known function. Human FOXP2 gene and evolutionary conservation is shown in and multiple alignment (at bottom of figure) in this image from the UCSC Genome Browser. Note that conservation tends to cluster around coding ...
