The “five fingers of evolution” is a concept that encapsulates five interconnected entities shaping the evolutionary landscape: natural selection, genetic drift, gene flow, mutation, and non-random mating. These fingers work in tandem to drive the evolution of species, shaping their traits, survival, and diversification. Each of these entities plays a distinct role in influencing the … Read more

The ocean lithosphere refers to the outermost rigid layer of Earth’s crust beneath the ocean basins, composed primarily of oceanic crust. At ocean trenches, the denser oceanic lithosphere converges with less dense continental lithosphere, causing the oceanic lithosphere to sink beneath the continental lithosphere in a process known as subduction. This process plays a crucial … Read more

Trophic levels represent each step in a food chain, with producers forming the base and consumers occupying higher positions. Energy transfer occurs as biomass is consumed from one level to the next, but only a fraction of this energy is retained. The percentage of energy remaining at each trophic level is determined by factors such … Read more
