Many evolutionary anthropologists view cooperation as core to the evolutionary success of our species. Concurrently, many sustainability scientists view cooperation as core to the future sustainable development of our species. When it comes to biology education, however, it is unclear how or if students are being engaged in these scientific…

Academic performance scores of medical students have been associated with many variables. Students' sociodemographic characteristics, study times and approaches may affect academic performance separately. Examining academic performance by considering all these variables together can improve medical education. The aim of this study is to determine…

Scientific advances in genetic analysis have been made possible in recent years by technical developments in computational biology, or bioinformatics. Bioinformatics has opened up the human genome to diverse analyses involving automated laboratory hardware and machine learning algorithms and software. As part of an emerging field of social…

Like the figurative apple for the teacher, the tomato is a well-known food symbol representing a variety of cuisines. We drew on current scientific research and partnerships with classroom teachers to develop a case study activity consisting of four layers to teach concepts of plant biology and genetics to middle and high school students. The goal…

The current study examined the criticism component of expressed emotion (EE) and attributions in parents of adults diagnosed with schizophrenia/schizoaffective disorder (S/SA) or high functioning autism/Asperger's. Consistent with study hypotheses, parents of adults diagnosed with autism/Asperger's disorder exhibited lower levels of high…

"Nothing in biology makes sense except in the light of evolution." This was the title of an essay by geneticist Theodosius Dobzhansky writing in 1973. Many causes have been given for the increased Cesarean section rate in developed countries, but biologic evolution has not been one of them. The C-section rate will continue to rise, because the…

Gene-environment interaction (G x E) has been treated as both a statistical phenomenon and a biological reality. It is argued that, although there are important statistical issues that need to be considered, the focus has to be on the biological implications of G x E. Four reports of G x E deriving from the Dunedin longitudinal study are used as…

Despite decades of research, the causal mechanisms of hot flashes are not adequately understood, and a biopsychosocial perspective on hot flashes remains underdeveloped. This article explores overlooked parallels between hot flashes and panic attacks within 5 areas: course and symptomatology, physiological indicators, neurocircuitry and…

Presents a perspective on evolution which includes an explanation of the textbook theory of evolution, a review of evolutionary theory before Darwin, and an outline of Darwin's early theories. Describes a rethinking of evolutionary theory to include natural selection, conservative selection, discontinous evolution, catastrophism, and the…

Reports on experiments conducted on two biological clocks, in organisms in the plant and animal kingdoms, which indicate that biological oscillation can be arrested by a single stimulus of a definite strength delivered at the proper time. (GS)

Written in response to an earlier article questioning certain aspects of evolution theory. Discusses ontogeny and phylogeny, the basis of evolution, chance or purpose in evolution, micro and macro-evolution, reversibility, and the evolution processes today. (MA)

Reviews new documentation of the extent, timing, origins, dispersal mechanisms, and impacts of biological invasions in the Great Lakes basin. (ZWH)

This chapter discusses biological contributions to adolescent female sexual development and, based on a developmental systems framework, suggests future research directions.

Offers an opposing view to Darwin's statement that evolution occurs through gradual change, using fossil species and modes of evolution to lend support to the author's model of "punctuated equilibria," in which... "Lineages change little during most of their history, but events of rapid speciation occasionally punctuate this…

Describes age-related changes in central nervous system pertinent to biology of suicide. Reviews postmortem biological studies of brains of suicides and suicide attempters. As suicide attempts in elderly are characterized by violence, discusses biological studies of impulsive violence. Describes data on effect of degenerative diseases on serotonin…
