The title of the post is misleading. This is not intended to be a confirmation of the modern evolutionary theory. This paper is about HOW actually evolution of certain aspects of the nematodes happen, not about whether evolution happens or not at all.
The modern theory of evolution considers three different mechanisms in which evolution occur:
* Natural selection (the only one described by Darwin), which consists in the differential reproduction of organisms (let's just say organisms, to keep it simple) determined by inheritable traits (adaptive traits.
* Genetic drift, which consists in the "random" change in the frequency of a gene in a population.
* Genetic flow, which consists in the transference of genes among populations.
From the summary of the paper:
"We propose that developmental evolution is primarily governed by selection and/or selection-independent constraints, not stochastic processes such as drift in unconstrained phenotypic space."
Put simply, this paper says that natural selection is the prevailing mechanism in developmental evolution.
