Arthropod genomics beyond fruit flies: bridging the gap between proximate and ultimate causation

The objective of the research were to investigate level parasitization, immature development period, longevity of adult parasitoids, along with number of progeny and parasitoid sex of Psyttalia sp. attacking larvae of Bactrocera dorsalis. This experiment was conducted in Laboratory of Entomology, Department Plant Pest and Diseases Faculty of Agriculture, Sriwijaya University from March to September 2007. The result showed that the average level of parasitization of Psyttalia sp. reached 24.24%. The highest one was 30% and the lowest was 16.7%. The immature development period of Psyttalia sp. ranged from 24-31 days with average 27.5 days. Longevity of imago parasitoids which stored at 5 0C was 14.1 days. In the research, the progeny of parasitoids which produced was females with percentage of females reached 59.99% and percentage of males reached 39.99%.Keywords: fruit flies, Bactrocera dorsalis, parasitoid, Psyttalia sp.

Psychological Capacities

Many people accept that chimpanzees, dolphins, and some other animals can think and feel. But these cases are just the tip of a growing iceberg. If biologists are right, fruit flies and plants make decisions, worms and honeybees can be trained, bacteria communicate linguistically, and neurons have preferences. Just how far does cognition go? This book is the first to critically consider this question from the perspective of the entire range of new ascriptions of psychological capacities throughout biology. It is also the first to consider the role of mathematical models and other quantitative forms of evidence in prompting and supporting the new ascriptions. It defends a default literal interpretation of psychological terms across biological domains. It also considers the implications of the literal view for efforts to explain the mind’s place in nature and for traditional ways of distinguishing the superior moral status of humans relative to other living beings.

Ultimate Causation

AbstractYawning is highly contagious, yet both its proximate mechanism(s) and its ultimate causation remain poorly understood. Scholars have suggested a link between contagious yawning (CY) and sociality due to its appearance in mostly social species. Nevertheless, as findings are inconsistent, CY’s function and evolution remains heavily debated. One way to understand the evolution of CY is by studying it in hominids. Although CY has been found in chimpanzees and bonobos, but is absent in gorillas, data on orangutans are missing despite them being the least social hominid. Orangutans are thus interesting for understanding CY’s phylogeny. Here, we experimentally tested whether orangutans yawn contagiously in response to videos of conspecifics yawning. Furthermore, we investigated whether CY was affected by familiarity with the yawning individual (i.e. a familiar or unfamiliar conspecific and a 3D orangutan avatar). In 700 trials across 8 individuals, we found that orangutans are more likely to yawn in response to yawn videos compared to control videos of conspecifics, but not to yawn videos of the avatar. Interestingly, CY occurred regardless of whether a conspecific was familiar or unfamiliar. We conclude that CY was likely already present in the last common ancestor of humans and great apes, though more converging evidence is needed.
