“…It is usually referred to simply as fly, fruitfly or Drosophila (the same terms we will use throughout this document), although the genus Drosophila has thousands of species and not all feed on fruits; only D. suzukii poses as a real threat to fruticulture as a pest ( Cook and Parks, 2022 ). From helping to establish basic principles of genetics more than 100 years ago ( Morgan, 1910 ), Drosophila then became the pupil of evolutionary biology, with a special participation of Theodosius Dobzhansky in establishing a strong research program on evolutionary population genetics in the USA and in Brazil ( Glick, 2008 ). Dobzansky’s visits to Brazil in the 1950’s, to study tropical species drew great attention to drosophilids, and laid the foundation of strong research groups in the area of evolution and population genetics, particularly at the University of São Paulo ( Magalhães and Vilela, 2014 ).…”

Drosophila melanogaster is undoubtedly one of the most useful model organisms in biology. Initially used in solidifying the principles of heredity, and establishing the basic concepts of population genetics and of the synthetic theory of evolution, it can currently offer scientists much more: the possibility of investigating a plethora of cellular and biological mechanisms, from development and function of the immune system to animal neurogenesis, tumorigenesis and beyond. Extensive resources are available for the community of Drosophila researchers worldwide, including an ever-growing number of mutant, transgenic and genomically-edited lines currently carried by stock centers in North America, Europe and Asia. Here, we provide evidence for the importance of stock centers in sustaining the substantial increase in the output of Drosophila research worldwide in recent decades. We also discuss the challenges that Brazilian Drosophila scientists face to keep their research projects internationally competitive, and argue that difficulties in importing fly lines from international stock centers have significantly stalled the progression of all Drosophila research areas in the country. Establishing a local stock center might be the first step towards building a strong local Drosophila community that will likely contribute to all areas of life sciences research.

“…Many Brazilian geneticists were directly or indirectly linked to Theodosius Dobzhansky, one of the leading figures of the evolutionary discussion arena in the USA at that time. Dobzhansky was attracted to Brazil by a Rockfeller Foundation project and, while in São Paulo, he was mainly involved in teaching and genetic research with natural populations of Drosophila flies (Glick 2008). However, surprisingly, his studies on plant distribution in the Amazon represented a turning point for tropical pollination studies.…”

Pollination research in Brazil virtually started with Fritz Muller, whose insights supported Darwin's evolutionary theory. Pollination systems of Brazilian plants were studied mainly by travelling researchers until early last century when native or resident geneticists began to use floral biology information to deal with crop acclimatization and breeding, later applying similar experiments and techniques to investigate native plants. Bee geneticists studied common pollinators of crops, such as coffee and Citrus, and even the introduction of feral African honeybees, despite their associated problems, stimulated pollination research. Geneticists attracted Dobzhansky to Brazil, where his research on tree distribution in the Brazilian Amazon represented a turning point for tropical pollination research by prompting the discovery of long-distance pollinating bees, thus bringing pollination back to mainstream evolutionary research. Tropical pollination studies stimulated the emergence of research groups in the Amazon and São Paulo states. In 1998, a seminal conference held in São Paulo called for the need to conserve pollinators and pollination systems. Subsequent research has been integrated under the Brazilian Pollinators Initiative, with research groups established throughout the country. A revived International Pollination Course, a National Pollination Symposium, and cooperative efforts to tackle complex interaction networks may direct future pollination research in Brazil.

“…O contato com Klineberg ocorreu por intermédio do geneticista Theodosius Dobzhansky, professor de Columbia (Klineberg, 1984, p.70-71). Dobzhansky ministrara aulas para Dreyfus em 1943, em um curso sobre evolução das espécies na USP, tendo iniciado, na ocasião, pesquisas em genética das populações examinando os cruzamentos de moscas drosófilas (Glick, 2008 Mixing of closely related races may even lead to increased vigor. As for the most distantly separated races, there is no basis in fact to think that either biological stimulation or deterioration follows crossing.…”

Resumo Otto Klineberg, professor de psicologia social na Universidade de Columbia, assegurou que os testes de inteligência eram uma ferramenta para legitimar hierarquias raciais. Ele conduziu numerosos estudos sobre as relações entre negros, brancos, índios e grupos de imigrantes nos Estados Unidos e na Europa na qual ressaltou que os aspectos ambientais superavam os fatores raciais. Klineberg concebia o Brasil como um ambiente privilegiado para demonstrar que os testes de inteligência não tinham qualquer base científica. O presente artigo tem um foco triplo: três estudos realizados por Klineberg entre 1927 e 1935; suas experiências no Brasil de 1945 a 1947 como professor da Universidade de São Paulo, quando ele tentou investigar a relação entre testes de inteligência e condições socioeconômicas em escolas do Rio de Janeiro; e sua atuação inicial na Unesco, após a 2a Guerra Mundial, quando muitos ainda estavam convencidos que os testes de inteligência eram uma forma adequada para medir as chamadas habilidades inatas.
