The history of geneticscan be represented on a timeline of events from the earliest work in the 1850s, to the DNAera starting in the 1940s, and the genomicsera beginning in the 1970s. Early timeline. [edit] 1856–1863: Mendel studied the inheritance of traitsbetween generations based on experiments involving garden pea plants.
The primacy of population thinking: the genetic diversity carried in natural populations is a key factor in evolution. The strength of natural selection in the wild was greater than expected; the effect of ecological factors such as niche occupation and the significance of barriers to gene flow are all important.
The Nazca culture (also Nasca) was the archaeological culture that flourished from c.100 BC to 800 AD beside the arid, southern coast of Peru in the river valleys of the Rio Grande de Nazca drainage and the Ica Valley. [ 1 ] Strongly influenced by the preceding Paracas culture, [ 2 ] which was known for extremely complex textiles, the Nazca ...
Genetics is the study of genes, genetic variation, and heredity in organisms. [ 1 ][ 2 ][ 3 ] It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance ...
Genetics is the study of genes and tries to explain what they are and how they work. Genes are how living organisms inherit features or traits from their ancestors; for example, children usually look like their parents because they have inherited their parents' genes. Genetics tries to identify which traits are inherited and to explain how ...
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological, medical, historical and forensic implications and applications. Genetic data can provide important insights into human ...
Non-Mendelian inheritance. Non-Mendelian inheritance is any pattern in which traits do not segregate in accordance with Mendel's laws. These laws describe the inheritance of traits linked to single genes on chromosomes in the nucleus. In Mendelian inheritance, each parent contributes one of two possible alleles for a trait.
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. Genes and culture continually interact in a feedback ...
