Great exaptations
Long interspersed nuclear elements (LINEs) are among the most successful parasitic genetic sequences in higher organisms. Recent work has discovered many instances of LINE incorporation into exons, reminding us of the hazards they pose to genes in their vicinity as well as their potential to be co-opted for the host's purposes.
متن کاملCommunication signals and sound production mechanisms of mormyrid electric fish.
The African weakly electric fishes Pollimyrus isidori and Pollimyrus adspersus (Mormyridae) produce elaborate acoustic displays during social communication in addition to their electric organ discharges (EODs). In this paper, we provide new data on the EODs of these sound-producing mormyrids and on the mechanisms they use to generate species-typical sounds. Although it is known that the EODs ar...
متن کاملMinireview Great exaptations
Picking up LINEs The genomes of higher organisms are littered with repetitive sequence elements, and evidence for how this came to be is accumulating through a combination of bench work and bioinformatics. Long interspersed nuclear elements (LINEs or L1s) are retrotransposons that have generated integrated DNA copies of themselves through RNA intermediates. Intact L1 RNAs encode two proteins, O...
متن کاملAdaptations, exaptations, and spandrels.
Adaptation and natural selection are central concepts in the emerging science of evolutionary psychology. Natural selection is the only known causal process capable of producing complex functional organic mechanisms. These adaptations, along with their incidental by-products and a residue of noise, comprise all forms of life. Recently, S. J. Gould (1991) proposed that exaptations and spandrels ...
