In 2015 an adoption study that compared Swedish male-male full-sibships in which at least one member was reared by one or more biological parents and the other by adoptive parents was published. Parental education level was rated on a 5-point scale and each additional unit of rearing parental education was associated with 1.71 points higher IQ.
Molecular biology – study of biology and biological functions at the molecular level, with some cross over from biochemistry. Structural biology – a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules. Health sciences and human biology – biology of humans.
in full display. The peacock's ornamental train (grown anew in time for each mating season) is a famous adaptation. It must reduce his maneuverability and flight, and is hugely conspicuous; also, its growth costs food resources.
Sister Irene is among the pioneers of modern adoption, establishing a system to board out children rather than institutionalize them. Adoption is a process whereby a person assumes the parenting of another, usually a child, from that person's biological or legal
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
Also gastrocoel. The central internal cavity of the gastrula in most animal embryos, fated to develop into the lumen of the digestive tube ; the primitive gut. The archenteron initially has only one open end, known as the blastopore. B birth blastocoel Also blastocoele, blastocele, cleavage cavity, and segmentation cavity.

Emergent evolution – Evolutionary biology; Epic of evolution – Evolutionary narrative that blends views; Evolution window – Narrow band of mutation step size that is conducive to significant evolutionary progress; Evolutionary dynamics – Study of mathematical principles in evolutionary biology
The gene-centered view of evolution, gene's eye view, gene selection theory, or selfish gene theory holds that adaptive evolution occurs through the differential survival of competing genes, increasing the allele frequency of those alleles whose phenotypic trait effects successfully promote their own propagation.
