Evolution is defined as the change in the inherited traits of a population of organisms through successive generations. When living organisms reproduce, they pass on to their progeny a...
15 maj 2013 · Contrary to Gánti’s solution, the evolutionary conception of life treats life as a collective phenomenon, therefore the capacity of evolving (the reproduction is one of requirements for evolution) is considered as a real and not a potential property of life.

This theoretical framework concomitantly depicts both the microcosm—the biology, chemistry, and physics of the existing living cell—and the macrocosm—the astrophysical and biogeophysichemical (geospheric, hydrospheric, atmospheric, biospheric) process underlying the evolution of life on Earth.
31 paź 2023 · Despite compelling correlations between the behavior of chromosomes during meiosis and Mendel’s abstract laws, the Chromosomal Theory of Inheritance was proposed long before there was any direct evidence that traits were carried on chromosomes.
