Sentences with word «macroevolutionary»

I suggest that the true source of macroevolutionary change lies in the non-linear, or chaotic, dynamics of the relationship between genotype and phenotype — the actual organism and all its traits.
Similarly, there is no known intrinsic biological limit to the ability of adaptive microevolutionary change to continually and indefinitely modify, over sufficient lengths of time, the gross morphology of any particular form, i.e. observable macroevolutionary change up through the higher taxonomic levels.
(Please note: when I speak about evolution, I'm referring to Darwin's macroevolutionary theory: life began millions of years ago from a kind of primordial ooze that gave rise to single - celled creatures, which then evolved into more complex ones, all the way up to we humans.)
The fossil record does not show macroevolutionary changes.
With luck, Cooper adds, these experiments will illuminate «how microevolutionary processes may impinge on macroevolutionary trends.»
I find it more and more fascinating, especially macroevolutionary stuff.
I repeat, the only significant difference between microevolution and macroevolution is the time scale (and thereby relative morphological change) under consideration where a morphological change observable at the macroevolutionary scale is simply the acc - umulated adaptations at the microevolutionary scale.
Exactly how genetic alterations brought about these macroevolutionary changes, however, has proved difficult to ascertain.
All information will be presented within a comparative phylogenetic framework, so that evolutionary novelties (e.g., the haplorhine retinal fovea) can be understood in terms of the macroevolutionary processes responsible for the novel feature's appearance.
The macroevolutionary consequences of phenotypic integration: from development to deep time
It certainly doesn't communicate the macroevolutionary picture.
