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.

What is the accumulation of differences between groups that lead to formation of new species?
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.
What are the two factors that affect speciation?
The two factors that affect speciation are isolation, which can be geographic or reproductive, and genetic divergence, where populations accumulate genetic differences that prevent interbreeding. These factors can lead to the formation of new species over time.
What is divergence in evolution?
Divergence in evolution refers to the process by which two or more related species become increasingly different from each other over time. This often occurs when populations of a species become isolated and adapt to different environments or ecological niches, leading to the development of distinct characteristics and traits. Divergence is a key mechanism driving the formation of new species.
What percentage of the nucleotides in the chicken are different from those of the mouse?
Approximately 45-50% of the nucleotides in the chicken genome are different from those in the mouse genome. This represents the genetic divergence between these two species.
What are three steps that lead to speciation?
Geographic isolation: Populations become separated by physical barriers, preventing gene flow between them. Genetic divergence: Isolated populations accumulate genetic differences through mutation, genetic drift, and natural selection. Reproductive isolation: Genetic differences accumulate to the point where populations can no longer interbreed and produce viable offspring, leading to the formation of new species.
The accumulation of differences between populations that once formed a single population is called?
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.
The accumulation of differences between species or populations is called?
The accumulation of differences between species or populations is called genetic or evolutionary divergence. This process occurs over time as organisms adapt to different environmental conditions or through genetic drift and natural selection.

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.
What process occurs when local units of a population become reproductively isolated from other units?
genetic divergence
What are the 3 stages in formation of a new species?
The three stages in the formation of a new species are isolation, divergence, and reproductive isolation. Isolation occurs when a population is separated into two groups, leading to genetic differences. Divergence happens as each group adapts to its environment, resulting in further genetic changes. Finally, reproductive isolation develops when the two groups can no longer interbreed successfully.
What are the two factors that affect speciation?
The two factors that affect speciation are isolation, which can be geographic or reproductive, and genetic divergence, where populations accumulate genetic differences that prevent interbreeding. These factors can lead to the formation of new species over time.

Does convergent evolution result in speciation?
All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.

What are the major laws in evolution?
Answer 1As there is only one law of evolution, which is the natural " Law of evolution". All others are false. The Law of evolution is the naural changes in all things through better eating, living conditions, better health care and so on. The "Law of evolution" has been going on since our first parents. The "Theory of evolution" is according to mans own ides.Answer 2There are a number of "laws of evolution", although I could not tell you whether they are "major" or not. A few examples:- The law of genetic divergence of reproductively isolated populations. This states that, when the entirety of the population gene pool is assayed, one will observe divergence between reproductively separated populations. More often than not, such genetic divergence may be associated with morphological and behavioural divergence.- Evolution is irreversible. On the level of the population gene pool, this means that genetic divergence between separated populations will only increase, never decrease. On the level of the single lineage, this means that one should not expect to see a reversal of a feature to an earlier state on the genetic level: the chances are massively against such an occurrence, and decrease with every offset basepair. Note that this law specifies divergence on the genetic level: even diverging genetics may still produce convergent phenotypes.See the YouTube video linked below for a more indepth treatise on some of the laws of evolution.
