On polymorphism for discrete evolutionary dynamics driven either by selection or segregation distortion
(Springer, 2018-05)
We revisit some problems arising in the context of multiallelic discrete-time and deterministic evolutionary dynamics driven first by fitness differences and then by segregation distortion. In the model with fitness, we ...
Phylogeny and evolutionary patterns of South American octodontoid rodents
(Polish Academy of Sciences. Institute of Paleobiology, 2013-03)
Octodontoidea is the most diverse clade of hystricognath rodents, and is richly recorded in South America since at least the Oligocene. A parsimony-based morphological phylogenetic analysis of a wide range of extant and ...
Building General Hyper-Heuristics for Multi-Objective Cutting Stock Problems
(Computación y Sistemas;Vol. 16 No. 3, 2012-08-31)
Abstract: In this article we build multi-objective hyperheuristics (MOHHs) using the multi-objective evolutionary algorithm NSGA-II for solving irregular 2D cutting stock problems under a bi-objective minimization schema, ...
Incomplete lineage sorting and hybridization in the evolutionary history of closely related, endemic yellow-flowered Aechmea species of subgenus Ortgiesia (Bromeliaceae)
(Botanical Soc Amer Inc, 2017-07-01)
PREMISE OF THE STUDY: The yellow-flowered Aechmea subgenus Ortgiesia (yfAsO) (Bromeliaceae) is a group of seven morphologically similar bromeliads found mostly in the southern Brazilian Atlantic rainforest. The recent ...
Dental ontogeny in extinct synapsids reveals a complex evolutionary history of the mammalian tooth attachment system
(The Royal Society, 2018-11)
The mammalian dentition is uniquely characterized by a combination of precise occlusion, permanent adult teeth and a unique tooth attachment system. Unlike the ankylosed teeth in most reptiles, mammal teeth are supported ...
Perception of brazilian citizens about Darwinism and the (Non) Influence of God in the evolutionary process
(Int Organization Center Acad Research, 2014-01-01)
The current context is unique in relation to the teaching of evolution in Brazil and the population's perception of evolution. On the one hand, it is said often about Darwinism in various media, especially due to the ...
