Steps in evolution
In summation, to understand the evolution of a flying lineage, we must follow these steps in this order: (1) Understand the phylogeny of that group; what its origins were. (2) Understand the functional morphology relevant to flight, and how that changed from the nonflying ancestor to the earliest flyer.by Institute for Research in Biomedicine (IRB Barcelona) Timeline of early eukaryotic evolution unveiled the mitochondrial acquisition occurred in a scenario of increasing complexity. Credit ...The evolution of eyes has taken several major steps in development. Some of the eye steps have been discussed above. We know from computer models, 12 and deductive reasoning, that eyes can evolve ...

However, one mystery about multicellular organisms is why cells did not return back to single-celled life. “Unicellularity is clearly successful — unicellular ...When conducting research, the scientific method steps to follow are: Observe what you want to investigate. Ask a research question and make predictions. Test the hypothesis and collect data. Examine the results and draw conclusions. Report and share the results.

In AEM, the reaction typically involves four concerted proton and electron transfers with the metal centers as active site (M), ...
Software Evolution is a term which refers to the process of developing software initially, then timely updating it for various reasons, i.e., to add new features or to remove obsolete functionalities etc. The evolution process includes fundamental activities of change analysis, release planning, system implementation and releasing a system to ...Modern theories of the evolution of human cooperation focus mainly on altruism. In contrast, we propose that humans’ species-unique forms of cooperation—as well as their species-unique forms of cognition, communication, and social life—all derive from mutualistic collaboration (with social selection against cheaters). In a first step, humans became obligate collaborative foragers such ... ….

When two viruses infect a cell at the same time, they may swap genetic material to make new, "mixed" viruses with unique properties. For example, flu strains can arise this way.
