Thus, this study provides molecular evidence for distinct modes of nutrient acquisition between the visceral and neurotropic flukes of birds.doi:10.1038/s41598-018-37669-2Leontovyč, RomanYoung, Neil D.Korhonen, Pasi K.Hall, Ross S.Bulantová, JanaJeřábková, VeronikaKašný, MartinGasser, Robin B.Horák, PetrNature Pub...
In addition, contrasting evidence to the “easy encounter” hypothesis exists from malarial parasites of birds in equatorial areas, where high host diversity is coupled with low host abundance. The latter suggests that the probability of encountering a closely related host is indeed low (i.e., a...

In the phylogenetic analyses, the turtle was found to be closely related to the alligator. Also, we found that the turtle had diverged after the divergence of squamates and birds. This departs from previous hypotheses of turtle evolution and further suggests that turtles are the latest of ...
The natural products synthesized by organisms that were living a long time ago gave rise to their molecular fossils. These can consist of either the original unchanged compounds or they may undergo peripheral transformations in which their skeletons rema
cioides, and inferred the origin of trans-species polymorphisms between the two species by phylogenetic reconstruction and Bayesian cluster analysis. The two species could be clearly distinguished by population cluster analysis. Despite the large number of mutational differences, we still detected sharing...
We present archaeological and molecular evidence for the raising of chickens for egg production, based on material from 12 different archaeological sites spanning a millennium and a half. These eggshells were recovered in high abundance at all of these sites, suggesting that chickens may have been ...
The earliest fossil evidence of terrestrial animal activity is from the Ordovician, ~450 million years ago (Ma). However, there are earlier animal fossils, and most molecular clocks suggest a deep origin of animal phyla in the Precambrian, leaving open the possibility that animals colonized land ...
In this review, we will discuss molecular evidence of the origin of SARS-CoV-2. We also discuss molecular evolutionary insights into the selective forces leading to the current pandemic, as well as the future evolutionary trajectories of SARS-CoV-2....
The obvious first step in any systematics or population genetics study is to focus on a group of organisms or a level of interest. We assume that these issues are self-explanatory and the reader is referred to the accompanying volume (EXS 92) for example
