Allopatric speciation (from Ancient Greek ἄλλος allos meaning “other” and πατρίς patris “fatherland”) also referred to as geographic speciation vicariant speciation or its earlier name the dumbbell model : 86 is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow.

Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.Different characteristics tend to exist within any given population as a result of mutation genetic recombination and other sources of genetic variation.

Marine life or sea life or ocean life is the plants animals and other organisms that live in the salt water of the sea or ocean or the brackish water of coastal estuaries.At a fundamental level marine life affects the nature of the planet. Marine organisms mostly microorganisms produce oxygen and sequester carbon.Shorelines are in part shaped and protected by marine life and …

Enceladus (/ ɛ n ˈ s ɛ l ə d ə s /) is the sixth-largest moon of Saturn.It is about 500 kilometers (310 mi) in diameter about a tenth of that of Saturn’s largest moon Titan.Enceladus is mostly covered by fresh clean ice making it one of the most reflective bodies of the Solar System.Consequently its surface temperature at noon only reaches −198 °C (−324 °F) far colder than a …

Evidence of common descent of living organisms has been discovered by scientists researching in a variety of disciplines over many decades demonstrating that all life on Earth comes from a single ancestor.This forms an important p…
