The evolutionary rates of speciation and extinction, their difference being diversification rate, shape current patterns of diversity across the tree of life. At equilibrium these three processes balance ( m + g = d ).
Which Increases The Rate Of Speciation. C) the rate increases as the extent of geographic barriers separating the two subsets increases. However, recent phylogenetic studies have found. Increased instances of hybrid formation d. Longer distance between divided groups.

Allopatric speciation, meaning speciation in “other homelands,” involves a geographic separation of populations from a parent species and subsequent evolution. It refers to the evolution of new species from the surviving ancestral species in which both the species continue to live in the same geographical region. Several evolutionary theories predict that rates of morphological change should be positively associated with the rate at which new species arise. Over time, it leads to arise of new and different.
Which variable increases the likelihood of allopatric speciation taking place more quickly?
Likewise, the number of species will decrease when extinction rates begin to overtake speciation rates. Longer distance between divided groups. Under some conditions, selection occurs quickly or radically. An increased mutation rate results in a no effect on the rate of speciation b decreases the rate of speciation c increases the rate of speciation Consider a species of snails that had been living with the same basic form for many thousands of years. Likewise, the number of species will decrease when extinction rates begin to overtake speciation rates.

Consider a species of snails that had been living with the same basic form for many thousands of years. Equivalent numbers of individuals in each population. When the rate of speciation is higher than the rate of extinction, then the number of languages is increasing and when the opposite is true, then the number of languages is decreasing.

Longer distance between divided groups. Such speciation could eventually happen via hybridization of existing languages. Rate of speciation increases due to reproductive isolation, which prevents mating between members of different species to accumulate genetic differences in the population.

B) the rate increases as the rate of genetic change increases in both subsets. The diversification rate hypothesis holds that tropical regions diversify faster due to higher rates of speciation (caused by increased opportunities for the evolution of reproductive isolation, or faster molecular evolution, or the increased importance of biotic interactions), or due to lower extinction rates.
