“…They revealed tight homologies between cellular plastides and cyanobacteria (i. e. Synechococcus) and between mitochondriae and phototrophic bacteria (i. e. Rhodopseudomonas) (Schwartz and Dayhoff, 1978;Schenk et al, 1987;Sitte and Eschenbach, 1991). Among a near endless list of symbioses, one important hypothesis concerns the endosymbiosis of one organism by another to explain the evolutionary origin of mitochondriae and plastides.…”

Molecular biology conferred enormous progresses in biosciences during the past few years. This paradigm permutation in biological research certainly challenges biological education. Nevertheless, this is no reason to fundamentally reorganise biological education at the universities. A most entire view of the matter should remain a central request which meets the capacity and imagination of students. Selected biological phenomena taken from the traditional treasury remain suitable in the future too to mediate basic biological ways ot thinking. Forthcoming syllabuses, however, will necessitate the expansion of this concept. The scope of the present contribution is to show, how the integration of molecular biology in the teaching of classical disciplines of biology may be reached. Choosing ecology and environmental biology as examples, molecular biology will not only strengthen explanation models of cause-effect relationships in these disciplines, but also will facilitate the interconnections to interdisciplinary fields such as health education, social, and political education. This may result in an entire structural concept of classical and molecular biology. The challenge of molecular biology to biological teaching Didactics of molecular biology ± what for?Recent developments in molecular biology contribute not only to research activities, but will also influence teaching of biology at the universities in the future. The present article aims to draw the attention of biology teachers to some of the demands of biological education in the 21 st century. Molecular biology may not only be understood as a simple necessity but also as a chance. Important proceedings frequently serve as headlines in the daily press and in TV causing sometimes emotional pros and cons in the public.

“…The green algal (chlorophyte), brown algal (chromophyte), and red algal (rhodophyte) lineages are probably phylogenetically separated by endosymbiotic events (Whatley and Whatley, 1981;Howe et al, 1992;Sitte and Eschbach, 1992;Blackwell and Powell, 1995). Recognition of disparate "protistan" lineages is supported by molecular data (e.g., Ariztia et al, 1991;Bhattacharya et al, 1995;Van de Peer and De Wachter, 1997;Sogin and Silberman, 1998), although a possible connection between plastid genomes of chromophytes and rhodophytes has been indicated (Wee et al, 1996;Bhattacharya, 1998).…”
