    Hershey–Chase experiment proves that phage genetic material is DNA. 1952: The Hershey–Chase experiment proves the genetic information of phages (and, by implication, all other organisms) to be DNA. [29] 1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30]

    A focus on new model organisms such as viruses and bacteria, along with the discovery of the double helical structure of DNA in 1953, marked the transition to the era of molecular genetics. In the following years, chemists developed techniques for sequencing both nucleic acids and proteins, while many others worked out the relationship between ...

    The Journey of Man: A Genetic Odyssey is a 2002 book by Spencer Wells, an American geneticist and anthropologist, in which he uses techniques and theories of genetics and evolutionary biology to trace the geographical dispersal of early human migrations out of Africa. The book was made into a TV documentary in 2003.

    They lived and worked on a farm which had been owned by the Mendel family for at least 130 years [11] (the house where Mendel was born is now a museum devoted to Mendel). [12] During his childhood, Mendel worked as a gardener and studied beekeeping. As a young man, he attended gymnasium in Troppau (Czech: Opava).

    William Bateson became a proponent of Mendelian genetics and had Mendel's work translated into English. It was with Bateson that Reginald Punnett helped establish the new science of genetics at Cambridge. He, Bateson and Saunders co-discovered genetic linkage through experiments with chickens and sweet peas. [10] A Punnett square

    The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.

    The genetic and archaeological evidence for this remains in question however. [59] A 2023 genetic study suggests that a similar human population bottleneck of between 1,000 and 100,000 survivors occurred "around 930,000 and 813,000 years ago ... lasted for about 117,000 years and brought human ancestors close to extinction."

    en.wikipedia.org/wiki/Genetics

    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.
