Although other animals can make simple tools, the expanded and complex material culture of humans is unprecedented in the animal kingdom. Tool making is a slow and late-developing ability in humans, and preschool children find making tools to solve problems very challenging. This difficulty in tool making might be related to the lack of familiarity with the tools and may be overcome by children's long term perceptual-motor knowledge. Thus, in this study, the effect of tool familiarity on tool making was investigated with a task in which 5-to-6-yearold children (n = 75) were asked to remove a small bucket from a vertical tube. The results show that children are better at tool making if the tool and its relation to the task are familiar to them (e.g., soda straw). Moreover, we also replicated the finding that hierarchical complexity and tool making were significantly related. Results are discussed in light of the ideomotor approach.


Mitochondrial DNA Diversity of Modern, Ancient and Wild Sheep (Ovis gmelinii anatolica) from Turkey: New Insights on the Evolutionary History of Sheep
Demirci, Sevgin; Bastanlar, Evren Koban; Dagtas, Nihan Dilsad; Pişkin, Evangelia; ENGİN, ATİLLA; Ozer, Fusun; Yuncu, Eren; Dogan, Sukru Anil; TOGAN, İNCİ ZEHRA (2013-12-11)
In the present study, to contribute to the understanding of the evolutionary history of sheep, the mitochondrial (mt) DNA polymorphisms occurring in modern Turkish native domestic (n = 628), modern wild (Ovis gmelinii anatolica) (n = 30) and ancient domestic sheep from Oylum Hoyuk in Kilis (n = 33) were examined comparatively with the accumulated data in the literature. The lengths (75 bp/76 bp) of the second and subsequent repeat units of the mtDNA control region (CR) sequences differentiated the five hapl...
Preschool teachers' perceptions of environmental education.
Güner, Zişan; Olgan, Refika; Çakıroğlu, Jale (null; 2011-09-19)
From past to today, environmental problems emerged due to many reasons and have deep influences on nature, various habitats and surely human beings. One of the major causes of these problems is human factor. Humans’ negative effec ts might be sourced from the lack of being sensitive and having positive attitudes towards environment. The environmental attitudes are laid in the foundation from early years (Evans, Brauchle, Haq, Stecker, Wong & Shapiro, 2007). Thus, providing environmental education for young ...
Re-evaluated conservation status of Salvia (sage) in Turkey I: The Mediterranean and the Aegean geographic regions
CELEP, FERHAT; Doğan, Musa; Kahraman, Ahmet (2010-01-01)
The precise evaluation of the conservation status of endemic and rare species is necessary in order to prevent their extinction. According to our current taxonomic revision of Turkish Salvia L., the Mediterranean and Aegean geographic regions of Turkey have 60 taxa, 32 of which are endemic (mainly local endemics), 5 of which are non-endemic rare, and the remaining 23 taxa are widely distributed. The rate of endemism is 53% in the area. The destruction of habitat through human encroachment such as urbanisati...
How Slippery Is Viscous Friction?
Prach, Anna; Kouba, Omran; Bernstein, Dennis S. (Institute of Electrical and Electronics Engineers (IEEE), 2019-06-01)
One of the many things that humans and many animals are very good at is picking up objects. Teaching robots to pick up objects is not so easy, however, for at least two reasons. First, the coefficient of friction may be unknown, and therefore, an object may slip through the robot's grasp. Although this uncertainty can be overcome by using a tighter grip, another issue arises, namely, that excessive force may crush the object. Furthermore, the length of the object must also be accounted for since the ultimat...
A Comparison of Brain Gene Expression Levels in Domesticated and Wild Animals
Albert, Frank W.; Somel, Mehmet; Carneiro, Miguel; Aximu-Petri, Ayinuer; Halbwax, Michel; Thalmann, Olaf; Blanco-Aguiar, Jose A.; Plyusnina, Irina Z.; Trut, Lyudmila; Villafuerte, Rafael; Ferrand, Nuno; Kaiser, Sylvia; Jensen, Per; Paeaebo, Svante (2012-09-01)
Domestication has led to similar changes in morphology and behavior in several animal species, raising the question whether similarities between different domestication events also exist at the molecular level. We used mRNA sequencing to analyze genome-wide gene expression patterns in brain frontal cortex in three pairs of domesticated and wild species (dogs and wolves, pigs and wild boars, and domesticated and wild rabbits). We compared the expression differences with those between domesticated guinea pigs...
