Darwin considered evolution to be caused due to : 1)small changes/variations that occured 2)these variations were directed specifically towards adapting to the environment(directional) 3)evolution was a slow process De Vries believed that evolution occured by: 1)large changes that occured 2)these changes were mutations and were stochastic or random, not directional 3)evolution occured in fits and starts and was not a slow ongoing process
Answer 1Two broad processes that make evolution possible are 1 : directional forces including mutation , migration and selection and 2: nondirectional forces that include random genetic drift , bottleneck effect , founders effect ,and chance variations .Answer 2Evolution is most commonly described as a combination of reproductive variation and differential reproductive success.Reproductive variation in itself is a "non-directional" phenomenon, that produces mostly random variations. Differential reproductive success (or: natural selection) is a "directional" phenomenon, that basically acts as a mechanism limiting the set of "directions" produced by random variation.
Contingent evolution is one of the forces of Darwin's theory of evolution. It is based on the concept of how power of accidents and happenstance shape the course of evolution.

Directional selection is a type of natural selection where individuals with traits that are better suited to their environment have a higher chance of survival and reproduction. This process can lead to the evolution of a population over time as certain traits become more common in the gene pool.
Directional selection is a type of natural selection where individuals with traits at one extreme of a spectrum have a higher chance of survival and reproduction. This leads to a shift in the average trait value of a population over time. Directional selection can drive the evolution of a population towards a specific trait or characteristic, as individuals with that trait are more likely to pass on their genes to the next generation.
Directional selection is a type of natural selection where individuals with traits that are more favorable for survival and reproduction are more likely to pass on their genes to the next generation. This process can lead to changes in the frequency of certain traits within a population over time, which is a key mechanism driving evolution.
Directional selection and disruptive selection are two types of natural selection that can drive evolution in a population. Directional selection occurs when individuals with a certain trait are favored over others, leading to a shift in the population towards that trait. This can result in the gradual evolution of the population towards that specific trait. Disruptive selection, on the other hand, occurs when individuals with extreme traits are favored over those with intermediate traits. This can lead to the population splitting into two distinct groups with different traits, potentially resulting in the evolution of two separate species. In summary, directional selection leads to a gradual shift towards a specific trait in a population, while disruptive selection can result in the divergence of a population into two distinct groups with different traits.
Disruptive selection and directional selection are two types of natural selection that impact the evolution of a population in different ways. Disruptive selection favors extreme traits at both ends of the spectrum, leading to the divergence of a population into two distinct groups. On the other hand, directional selection favors one extreme trait, causing the population to shift towards that trait over time. In summary, disruptive selection promotes diversity within a population, while directional selection drives the population towards a specific trait.
The interplay between disruptive and directional selection influences the evolution of a population by driving changes in the traits of individuals. Disruptive selection favors extreme traits, leading to the formation of distinct subgroups within the population. Directional selection, on the other hand, favors one extreme trait, causing a shift in the average trait value of the population over time. Together, these selection pressures can result in the diversification or adaptation of a population to its environment.
Directional selection is a type of natural selection where individuals with traits that are better suited to their environment have a higher chance of survival and reproduction. Over time, these advantageous traits become more common in the population, leading to evolutionary change.
directional
is address bus uni or Bi-directional
omni-directional is the opposite of directional. A directional antenna receives or sends more signal from or to the front than the sides or back.
Some are directional like the eagle F1, however most are not directional.
