The mechanisms of inflation within these pocket universes could function in a variety of manners, such as slow-roll inflation, undergoing cycles of cosmological evolution, or resembling of the Galilean genesis or other 'emergent' universe scenarios. Lehners goes on to discuss which one of these types of universes we live in, and how that is ...
Parallel speciation vs. parallel evolution [ edit ] Parallel evolution is a common phenomenon that occurs when separate yet closely related lineages evolve the same, non-ancestral trait as a result of inhabiting the same environment, and thus, facing the same selection pressures .
Parallel evolution is the similar development of a trait in distinct species that are not closely related, but share a similar original trait in response to similar evolutionary pressure. [ 1 ] [ 2 ] Parallel vs. convergent evolution
The right-hand species may undergo divergent, parallel, or convergent evolution at this amino acid position relative to the first species. When two species are similar in a particular character, evolution is defined as parallel if the ancestors were also similar, and convergent if they were not.
An extinct ribbonlike sea creature about the size of a human thumb was one of the earliest animals to evolve a precursor of a backbone. Scientists recently identified the animal’s nerve cord by ...
The theory of recapitulation, also called the biogenetic law or embryological parallelism—often expressed using Ernst Haeckel's phrase "ontogeny recapitulates phylogeny"—is a historical hypothesis that the development of the embryo of an animal, from fertilization to gestation or hatching (), goes through stages resembling or representing successive adult stages in the evolution of the ...
While most people know that a baby dog is called a puppy, many may not know what a baby elephant is called. In this fun infographic, explore the world of baby animals. Find out what they’re ...
Quantum fluctuations drop the shapes to a lower energy level, creating a pocket with a set of laws different from that of the surrounding space. Quantum The quantum multiverse creates a new universe when a diversion in events occurs, as in the real-worlds variant of the many-worlds interpretation of quantum mechanics.
