Groups of organisms separated from other populations can evolve to form different species over many generations. As bacteria can produce many generations in 24 hours they tend to evolve rapidly. Birds separated by land or water barriers need perhaps one or two hundred years to develop separate characteristics forced on the population by the environment. Individuals can not evolve, only species can evolve by passing on genetic material that enable their offspring to survive long enough to breed. If the environment acts against the offspring with certain characteristics eg a pale moth on a dark background, then those individuals are removed from the gene pool thus affecting the characteristics of the next generation.
Individuals evolve through natural selection, leading to changes in the characteristics of populations over time. These changes can eventually lead to the evolution of new species within a specific genus, which may contribute to the diversification of higher taxonomic groups such as phyla and kingdoms.
Populations evolve, individuals are selected.
Group Dynamics
The condition of individuals or groups of individuals that enables them to know the history, values and/or culture of individuals or groups of individuals different than their own.
Natural languages aren't created by individuals. They evolve among groups of people over very long periods of time.
LOSERS or INDIVIDUALS
individuals and interest groups
individuals do not evolve
individuals do not evolve
A species evolves over time through the process of natural selection acting on individuals within a population. Individuals themselves do not evolve, as evolution refers to changes in the genetic composition of a population over generations.
Altruistic traits evolve through mechanisms like kin selection and reciprocal altruism. Kin selection suggests that individuals are more likely to help relatives, as this increases the survival of shared genes. Reciprocal altruism occurs when individuals provide help to others with the expectation of receiving help in return, fostering cooperation within social groups. Over time, these behaviors can enhance the fitness of individuals within a population, leading to the persistence of altruistic traits.
