At least some of the evolutionary changes now emerging have clearly been convergent, meaning that natural selection has made use of the different mutations available in each population to accomplish the same adaptation.
Students document the evolutionary changes and justify why each takes place.
Drawing data from interviews and secondary data, it charts the evolutionary changes that the programme underwent.
The evolutionary changes could still accumulate in small steps, but these steps are taken more quickly at the time of speciation.
The evolutionary changes in developmental timing, heterochrony, have been a focus of research for decades (Raff 1996; Smith 2001; Maxwell and Harrison 2009).
This flight from dangerous levels of UV light, therefore, might explain many of the evolutionary changes that occurred during the Late Ediacaran and Early Cambrian, Meert says.
Evolutionary developmental biology (evo devo) is that part of biology concerned with how changes in embryonic development during single generations relate to the evolutionary changes that occur between generations.
The stronger the predation and more efficient the predator, the more drastic would be the evolutionary changes.
The evolutionary changes in bacterial traits were measured in a separate, short-term factorial experiment, at the end of the long-term evolutionary experiment.
Figure 2A shows estimates of the evolutionary changes of the number of OR genes when the currently popular mammalian phylogenetic tree is used.
To obtain insight into the biological significance of the evolutionary changes, we looked for differential trends between positively selected proximal promoters and proteins.
