Evolutionary Hypotheses for Human Childhood
The origins of human childhood have fascinated scholars from many disciplines. Some researchers argue that childhood, and many other human characteristics, evolved by heterochrony, an evolutionary process that alters the timing of growth stages from ancestors to their descendants. Other scholars argue against heterochrony, but so far have not offered a well-developed alternative hypothesis. Thi...
متن کاملFrail Hypotheses in Evolutionary Biology
In the last decades, under the headings of ‘‘mutation strategies,’’ ‘‘evolvability,’’ or ‘‘soft inheritance,’’ many ideas have been advanced on mechanisms assumed to promote innovative evolution beyond what one may anticipate from the classical model of random mutation and selection. Many population geneticists find these ideas superficially seducing but mathematically unfounded. While agreeing...
متن کاملEvolutionary ecology of spoken language: co-evolutionary hypotheses are testable.
Evolutionary ecological frameworks can give us new insights into the emergence of human adaptations such as language and cultural learning. There now exist several well-specied models of the social and ecological conditions in which the human capacity for language came under strong positive selection pressure. We critically review them, and ask how we can test them using archaeological evidenc...
متن کاملPairwise Comparison of Hypotheses in Evolutionary Learning
This paper investigates the use of evolutionary algorithms for the search of hypothesis space in machine learning tasks. As opposed to the common scalar evaluation function imposing a complete order onto the hypothesis space, we propose genetic search incorporating pairwise comparison of hypotheses. Particularly, we allow incomparability of hypotheses, what implies a partial order in the hypoth...
متن کاملEconomic and evolutionary hypotheses for cross-population variation in parochialism
Human populations differ reliably in the degree to which people favor family, friends, and community members over strangers and outsiders. In the last decade, researchers have begun to propose several economic and evolutionary hypotheses for these cross-population differences in parochialism. In this paper, we outline major current theories and review recent attempts to test them. We also discu...
