The evolutionary history of human chromosome
We report on a comparative molecular cytogenetic and in silico study on evolutionary changes in human chromosome 7 homologs in all major primate lineages. The ancestral mammalian homologs comprise two chromosomes (7a and 7b/16p) and are conserved in carnivores. The subchromosomal organization of the ancestral primate segment 7a shared by a lemur and higher Old World monkeys is the result of a p...
متن کاملHuman growth: evolutionary and life history perspectives.
Evolutionary and life history perspectives allow a fuller understanding of both patterns of growth and development and variations in disease risk. Evolutionary processes act to ensure successful reproduction and not the preservation of health and longevity, and this entails trade-offs both between traits and across the life course. Developmental plasticity adjusts the developmental trajectory s...
متن کاملEvolutionary ecology of human life history.
The human life history is characterized by several unusual features, including large babies, late puberty and menopause, and the fact that there is a strong cultural influence on reproductive decisions throughout life. In this review I examine human life history from an evolutionary ecological perspective. I first review the evidence for life history trade-offs between fertility and mortality i...
متن کاملEvolutionary history and phylogeography of human viruses.
Understanding the evolutionary history of human viruses, along with the factors that have shaped their spatial distributions, is one of the most active areas of study in the field of microbial evolution. I give an overview of our current knowledge of the genetic diversity of human viruses using comparative studies of viral populations, particularly those with RNA genomes, to highlight important...
متن کاملEvolutionary History of the Human Genome
Compositional genomics is an approach to the problem of the organization of eukaryotic genomes. Initially this approach consisted of analysing the base composition of complex eukaryotic genomes (such as the nuclear genomes of vertebrates) by using density gradient centrifugation in the presence of sequence-specific ligands. This approach revealed that vertebrate genomes are mosaics of very long...
