Non-metallic oxides are acidic (Except hydrogen, oxygen, helium, neon, argon) whereas metallic oxides are generally amphoteric or alkali (Except chromium, molybdenum, tungsten, niobium, tantalum, technetium, rhenium, ruthenium, osmium, bismuth)
Evolutionary relationships are traced in the classification of organisms. For classification of organisms, we look for similarities among organisms which allows us to group them. The more characteristics two species will have in common, the more closely they are related. It indicates that more closely two species are related, the more recently they would have had a common ancestor. Thus, classification of species is in fact a reflection of their evolutionary relationship.

They mean that species are a fundamental category of taxonomic classification, ranking below a genus or subgenus and consisting of related organisms capable of interbreeding.
Electronegativity and metallic character are inversely related - elements with high electronegativities tend to have low metallic character, and vice versa. Electronegativity measures an element's ability to attract and bind electrons, while metallic character refers to an element's tendency to lose electrons easily and form cations. Therefore, elements with high electronegativities typically have low metallic character because they hold onto their electrons more strongly.
metals lose electrons rather than gain them

Classification is the organization of organisms into groups based on shared characteristics, while evolution is the process by which organisms change over time. Classification reflects the relatedness of organisms based on their evolutionary history, with closely related organisms grouped together. Evolutionary relationships between organisms can provide insights into their classification and help refine the existing classification system.
