Although many authors have conceptualized cultural change as a Darwinian process, there is no generally agreed formal framework for def ...

Mendel concluded that each plant possesses two factors controlling a given characteristic; these could be identical (as in true-breeding plants) or different (as in hybrid plant) and in this case one dominates the other; these factors separate and go to different gametes when a parent reproduces The ...

Until recent times, anyone who survived 40 years was likely a grandparent and an elder; those still walking about at ages past 50 years were qui ...

The establishment of a pattern of files forming root hairs and non-root hairs in the root epidermis is a wellstudied developmental model system (Schiefelbein et al., 2009; Tominaga-Wada et al., 2011; Grebe, 2012). Root hair cells (H-cells) develop from cell files over the cleft of two underlying cor ...

History of genetic engineering

Genetic modification caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1973. Advances have allowed scientists to manipulate and add genes to a variety of different organism and induce a range of different effects. Since 1976 the technology has been commercialised, with companies producing and selling genetically modified food and medicine.
