The size-advantage model predicts the evolution of sex change if the relative reproductive success of the sexes changes with size or age. In the goby (Paragobiodon echinocephalus) the largest two fish, a male and a female matched by size, breed monogamously in each host coral. Because the ...
The canonical model of sex-chromosome evolution predicts that, as recombination is suppressed along sex chromosomes, gametologs will progressively differentiate, eventually becoming heteromorphic. However, there are numerous examples of homomorphic sex chromosomes across the tree of life. This homomorphy ha...

Rate of change of concomitantly variable codons 来自 国家科技图书文献中心 喜欢 0 阅读量: 38 作者: WM Fitch 摘要: It was previously shown that about 10% of the codons in cytochrome c are variable in any one mammalian species and any one point in time and that the positions of these ...
Mutations are the fundamental substrates of evolution because they generate variability within populations, enabling evolutionary change. The mutation rate (µ) is a crucial parameter for many calculations and predictive modelling in the fields of ecology and evolution, genetics, and genomics. Despite ...
This paper constructs a temporal scale for bacterial evolution by tying ecological events that took place at known times in the geological past to specific
Since the early 1990s, sea level rose at a mean rate of ∼3.1 mm yr−1 (refs 2, 3). However, over the last decade a slowdown of this rate, of about 30%, has been recorded4,5,6,7,8. It coincides with a plateau in Earth’s mean surface temperature evolution, known as the ...
