Evolution of Neonatal Imitation
September 2006 | Volume 4 | Issue 9 | e304 One reason to sequence the genomes of non-human organisms is to better understand our similarities and differences. And, at fi rst sight, it is hard to imagine a eukaryote more different from humans than Tetrahymena thermophila. A relative of Paramecium, this single-celled creature has a strong but fl exible exterior covered with rows of cilia; but it ...
متن کاملNeonatal Imitation in Rhesus Macaques
The emergence of social behaviors early in life is likely crucial for the development of mother-infant relationships. Some of these behaviors, such as the capacity of neonates to imitate adult facial movements, were previously thought to be limited to humans and perhaps the ape lineage. Here we report the behavioral responses of infant rhesus macaques (Macaca mulatta) to the following human fac...
متن کاملGender-Related Differences in Neonatal Imitation
Socio-emotional behaviour is in part sex-related in humans, although the contribution of the biological and socio-cultural factors is not yet known. This study explores sex-related differences during the earliest communicative exchange, the neonatal imitation in 43 newborn infants (3–96 hours old) using an index finger extension imitative gesture. Results showed that although the experimenter p...
متن کاملImitation in neonatal chimpanzees (Pan troglodytes).
This paper provides evidence for imitative abilities in neonatal chimpanzees (Pan troglodytes), our closest relatives. Two chimpanzees were reared from birth by their biological mothers. At less than 7 days of age the chimpanzees could discriminate between, and imitate, human facial gestures (tongue protrusion and mouth opening). By the time they were 2 months old, however, the chimpanzees no l...
متن کاملThe evolution of cooperation through imitation
Kandori, Mailath and Rob [1993] and Young [1993] showed how introducing random innovations into a model of evolutionary adjustment enables selection among Nash equilibria. Key to this result is that poorly performing strategies may be introduced in sufficient numbers that they begin to perform well. We examine imitation as an alternative propagation mechanism. If imitation is much more likely t...
