But Tiktaalik is so clearly an intermediate "link between fishes and land vertebrates," they said, that it "might in time become as much an evolutionary icon as the proto-bird Archaeopteryx," which bridged the gap between reptiles (probably dinosaurs) and today's birds.
At present as much as five evolutionary hypotheses have been proposed to explain the great variability of the genomic GC content, which can be split in two groups, on the bases of the nature of the forces driving the genome evolution, i.e. intra- or extra-cellular [ 2].
However, some fundamental problems such as how much evolutionary divergence separates human from mouse and to what extent the experimental observations on mouse can be applied to human are still poorly understood.
In this very general sense, how we think and behave are just as much part of our evolutionary heritage as are our average lifespan or limited sense organs.
In order to test these hypothetical scenarios for the selective advantages of coastal adaptations for Homo sapiens, we need more data deriving from an expanded spatiotemporal archaeological record, just as much as more formal evolutionary models and research strategies.
Most other biological processes, though just as much the product of evolutionary design, do not have a structure that motivates this sort of description.
By performing three independent alignments using the staggered indices with the optimized alignment parameters and then superimposing the resulting alignments to show all aligning sequences, the overall detection of conserved sequences has been improved by as much as 75% when evolutionary distant orthologous sequences are aligned.
We advocate an increased focus on trait loss not because it involves unprecedented mechanisms, but because it is often overlooked in evolutionary education whereas, as the whale situation shows, it is just as much a part of major evolutionary transitions as other sorts of trait changes are.
Its illustrations are drawn just as much from the annals of evolutionary psychology, behavioural economics and more traditional forms of psychology.
The point to remember is that such sectarian religious views disagree with each other as much as they disagree with evolutionary science.
