Biological evolution is the process of change and diversification of living things over time, and it affects all aspects of their lives morphology (form and structure), physiology, behaviour, and ecology.
This kind of habitat diversity among species of the subfamily sister to the rest of the PACMAD clade would be expected if climatic changes promoted the radiation and diversification of open habitat species at the time of the EOT.
Urbanization is understood quantitatively reflecting a growing population, increased population density, territorial expansion, and production development and qualitatively indicating changes in living standards and diversification of socioeconomic cultural patterns (28).
At the scale of individual reef units, the relative water depth zonation of the corals is controlled by ecological changes (substrate, nutrients, synecologic relations, and diversification of coral species).
The characterization of the molecular changes that underlie the origin and diversification of morphological novelties is a key challenge in evolutionary developmental biology.
Such dynamic changes enabled the introduction, amplification, and diversification of various toxin genes and pathogenicity factors and created the complex race structure that this organism displays today.
Characterizing the specific genetic changes that underlie the emergence and diversification of these traits together with the description of the selective pressures acting on them is key to understanding why and how semi-aquatic bugs diversified.
Of particular interest to both basic and applied plant biology are changes leading to the success and diversification of angiosperm lineages, beginning with the early, mostly species-poor lineages of angiosperms (Table 1) previously known as the ANITA grade (Amborellaceae, Nymphaeales, Illiciaceae, Trimeniaceae, and Austrobaileyaceae), followed by the magnoliids.
The extent to which these climatic fluctuations and associated vegetation changes affected the patterns of distribution and diversification of the fauna remains a central question in understanding the evolution of forest-associated taxa.
Oxyrrhis marina is a well-known model for heterotrophic protist biology, and is now emerging as a useful organism to explore the many changes that occurred during the origin and diversification of dinoflagellates by virtue of its phylogenetic position at the base of the dinoflagellate tree.
