Social life, evolution of intelligence, behaviour and human brain size
Social life is one of the most critical factors of the evolution of the behavior of non-human primates and humans. Several factors, such as an increase in brain size, adaptive modules, and grooming, are related to the complexities of social groups. Although some scientists have mentioned foraging as a rival hypothesis for the evolution of behavior, in this research, we tried to investigate the ...

miRNA-125b), so overall the generation of a new miRNA, its longevity and interdiction of translational processes may be relatively rapid neurogenetic process (Sethi and Lukiw, 2009). However, other biophysical and neurogenetic parameters such as miRNA secondary and tertiary structure, miRNA binding proteins, and other factors may significantly extend miRNA viability and action. Another poorly u...
متن کاملMitochondrial DNA sequence variation in human evolution and disease.
Germ-line and somatic mtDNA mutations are hypothesized to act together to shape our history and our health. Germ-line mtDNA mutations, both ancient and recent, have been associated with a variety of degenerative diseases. Mildly to moderately deleterious germ-line mutations, like neutral polymorphisms, have become established in the distant past through genetic drift but now may predispose cert...
متن کاملCopy number variation in human health, disease, and evolution.
Copy number variation (CNV) is a source of genetic diversity in humans. Numerous CNVs are being identified with various genome analysis platforms, including array comparative genomic hybridization (aCGH), single nucleotide polymorphism (SNP) genotyping platforms, and next-generation sequencing. CNV formation occurs by both recombination-based and replication-based mechanisms and de novo locus-s...
متن کاملThe Evolution of Human Genetic and Phenotypic Variation in Africa
Africa is the birthplace of modern humans, and is the source of the geographic expansion of ancestral populations into other regions of the world. Indigenous Africans are characterized by high levels of genetic diversity within and between populations. The pattern of genetic variation in these populations has been shaped by demographic events occurring over the last 200,000 years. The dramatic ...
