The researchers findings may seem counter – intuitive, seen since the last 65 million years, mammals in the number and diversity to expand, not to mention dominance in a variety of ecological functions. But it is precisely their success in numbers that could have led the contraction of their genomes. Larger population sizes make natural selection more efficient, said IU Bloomington evolutionary biologist Michael Lynch, who led the study generic viagra reviews . If we are correct, we have shown how to bring ancient genomic information together with the paleontological record to learn more about the past. .
LTRs come in a range of sizes and ages, and it is the age distribution of LTRs that interested Lynch and his colleagues. – This study started out as independent observations in the literature, Lynch said. The data we saw suggested a bulge in the age distribution of transposable elements in human and mouse. . Continue reading
