Theoretical research indicates that natural selection will increase existing seasonal imbalances between the supply of nectar from flowers and the demand from bees and other insects.
The aim of this study was to analyse the genomic regions that have been target of natural selection with respect to identifying the loci responsible mainly for fitness traits across six alpine cattle ...
An unusually cold winter in the U.S. in 2014 took a toll on the green anole lizard, a tree-dwelling creature common to the southeastern United States. A new study offers a rare view of natural selecti...
What matters more for the evolution of plants and animals, precipitation or temperature? Scientists have found a surprising answer: rain and snow may play a more important role than how hot or cold it...
This paper argues for two claims. First, despite a persistent appearance to the contrary in the philosophy of biology literature, the question of whether natural selection and genetic drift should be ...
In the recent philosophical literature, two questions have arisen concerning the status of natural selection: 1) Is it a population-level phenomenon, or is it an organism-level phenomenon? 2) Is it a ...
En la Teoa de la Selección Natural, el concepto de función biológica debe suponerse para delimitar el concepto de aptitud; y éste debe suponerse para delimitar el concepto de adaptación y también pa...
For evolution by natural selection to occur it is classically admitted that the three ingredients ofcvariation, difference in fitness and heredity are necessary and sufficient. In this paper, I show u...
There are two ways evolution by natural selection (ENS) is conceptualized in the literature. One provides a recipe’ for ENS incorporating three ingredients: variation, differences in fitness and heri...
The following describes one distinct sense of ‘mechanism’ which is prevalent in biology and biomedicine and which has important epistemic benefits. According to this sense, mechanisms are defined by t...
Our aims were to demonstrate that natural selection is operating on contemporary humans, predict future evolutionary change for specific traits with medical significance, and show that for some traits...
Natural selection can act on all the expressed genes of an individual, leaving signatures of genetic differeniation or diversity at many loci across the genome. New power to assay these genome-wide ef...
In the present study we have analyzed an extensive data set on the secondary sex ratio (SSR) including 59 335 goat kids born in 30 633 litters to 11 644 mothers on farms all over the Czech Republi...
Accounts of the concepts of function and dysfunction have not adequately explained what factors determine the line between low-normal function and dysfunction. I call the challenge of doing so the lin...
AMHERST, Mass. – Introducing a new approach that combines evolutionary and engineering analyses to identify the targets of natural selection, researchers report in the current issue of Evolution that ...
