divergence / divergent evolution
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
Some differences that can occur between members of a species include variations in physical characteristics, behavior, and genetic makeup. These differences are often influenced by factors such as environmental conditions, geographic location, and individual experiences. They can lead to diverse adaptations within a species, contributing to its overall resilience and survival.
An ecosystem includes populations of different species that interact with each other and their environment. These interactions can be competition for resources, predation, mutualism, or symbiosis. The balance between these populations is important for the overall health and stability of the ecosystem.
Population is a group of organisms of the same species actively reproducing with one another. Physical barriers and distance are typical causes of different populations. An individual may move from one population to another.
smallish genetic differences with each individual. this is obvious with the human species. eye color, hair color. things like that.

The accumulation of differences between populations that once formed a single population is called genetic divergence. This occurs over time due to factors such as genetic mutations, natural selection, genetic drift, and geographic isolation. Genetic divergence can eventually lead to the formation of distinct species.
Over time, the populations may become genetically distinct from one another due to accumulation of different mutations. This can lead to the evolution of new species if the genetic differences become significant enough to prevent successful reproduction between individuals from the two populations.
This is called genetic divergence. Over time, accumulated genetic differences between populations can lead to the formation of new species through a process known as speciation. This can occur through various mechanisms such as natural selection, genetic drift, and isolation.
limits or prevents gene flow between the populations, leading to independent evolution of their gene pools due to different selection pressures and mutations. Over time, this can result in the accumulation of genetic differences, potentially leading to the formation of distinct species.
Genetic divergence refers to the accumulation of genetic differences between populations as they evolve separately over time. It is the process by which new species arise from a common ancestor due to the accumulation of genetic changes that lead to reproductive isolation. Genetic divergence can result from various evolutionary mechanisms such as natural selection, genetic drift, and mutation.
New species form through a process known as speciation, which occurs when populations of the same species become reproductively isolated from each other, leading to the accumulation of genetic differences over time. This can happen through various mechanisms such as geographic isolation, behavioral differences, or genetic mutations.
This process is known as speciation, where a new species is formed due to the accumulation of genetic differences over many generations. As populations diverge through microevolution, they can eventually become reproductively isolated from each other, leading to the formation of distinct species.
Genetic variations, which arise from mutations and recombination of genetic material during reproduction, are responsible for the differences between species and between individuals in the same population. These variations can lead to differences in physical traits, behaviors, and other characteristics among organisms. Additionally, environmental factors can influence the expression of these genetic differences, leading to further diversity within and between populations.
Gene flow is the movement of genes between populations, which can introduce new genetic variations and prevent populations from diverging into separate species. It can increase genetic diversity, reduce differences between populations, and potentially lead to the spread of beneficial traits throughout a species. Gene flow is important in evolution as it promotes genetic exchange and maintains the genetic cohesion of a species.
Reproductive isolation prevents gene flow between populations, leading to the accumulation of genetic differences over time. This can drive the divergence of populations into distinct species, increasing overall biodiversity. By maintaining distinct gene pools, reproductive isolation allows for new adaptations to arise and for evolution to proceed in different directions.
The process of speciation, which leads to the formation of distinct species, is often driven by reproductive isolation. This isolation can occur through various mechanisms such as geographic barriers, genetic divergence, or behavioral differences, preventing interbreeding between populations and allowing for the accumulation of genetic differences that lead to distinct species.
