For example, the structure of flower parts is considered more significant than the shape of the leaves in flowering plants because leaf shape appears to evolve much more quickly. Much of the science of taxonomy has been concerned with judging which traits are most significant. If new evidence ...
Arthropod, any member of the phylum Arthropoda, the largest phylum in the animal kingdom, which includes such familiar forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes. About 84 percent of all known species of animals are mem
Flowering plants contain a multitude of secondary compounds, including flavonoids. The formation of these compounds requires many steps and should not be expected to be present in the more primitive organisms. Smith (1972) estimated that the formation of flavonoids accounts for the consumption of one...
authors have suggested that the biased sex ratio in this species is conditioned not only postzygotically (sex-differential sporophytic mortality) but also prezygotically, because the sex ratio of seeds is also female-biased, although to a lesser extent than the sex ratio of flowering plants. The...
2016). High-severity fire can stimulate increased flowering and cone production across a wide range of plants (Thomsen and Ooi 2022). Yet, high-severity fire can also cause seed death and limit seed dispersal, especially when fire temperatures are extreme (Bradstock et al. 1994; Gill, Hoecker...

He found that although the flowering time of the F2 plants and F3 families was undoubtedly determined above all by the node-number, certain F3 families occurred in which the flowering time was too long or too short for their node number. In order to explain both the general high correlation...
