When micro-evolution occurs over many generations as inherited characteristics leads to changes in populations what has occurred?
Macro-evolution. Or, more accurately, speciation.
What are 3 events that can lead up to speciation?
Isolation often leads to speciation, because as each isolated population evolves new characteristics, the separate populations eventually get DNA that is too different for the two to breed and have fertile offspring (this is the point when speciation has occurred). In the case that there is not isolation, the whole species must slowly evolve until it becomes a new species. However, here the line between where the speciation actually occurred becomes blurry, because it doesn't happen in a single generation.
Speciation that results from geographical isolation that leads to reproductive isolation?
Allopactric ( other country ) speciation.
How speciation takes place.?
because divergence leads to the formation of new species
What effect does reproductive isolation have on species?
It leads to speciation. many species in nature have evolved by this method.
What are conditions of speciation?
Speciation can occur due to allopatric isolation (geographic barrier), sympatric isolation (different ecological niches), or parapatric isolation (partial geographic barrier). It can also result from reproductive isolation, where individuals can no longer interbreed due to genetic, behavioral, or ecological barriers. Changes in chromosome number, mutations, and natural selection can also contribute to speciation.
How do change Genetic equilibrium lead to speciation?
Allele frequency is altered by genetic drift, natural selection, migration, mutation, or nonrandom mating. This results in a change in genetic equilibrium in a population that is evolving. Evolution leads eventually to speciation.
How does speciation take place?
several generations
What are the implications of asexual reproduction in the evolution of species?

Does a high birth to death ratios lead to smaller populations?
No, it is actually the opposite. A high birth rate and a low death rate leads to increased populations.
What is the difference between variables and factors in scientific terminology?
A factor is a type of variable. Usually, "factor" is another word for the independent variable. But it can be any variable that is a part of or contributes or leads to another variable.
How can the isolation of populations lead to specification?
it leads to specification because you separate the populations and a population with a certain trait will become dominant over a certain area of land or mass.
