Geographic isolation Low geneflow.
Geographic isolation is correct for apex
Low gene-flow
A low gene flow would increase speciation.
reproductive isolation
the formation of species
I will assume the word you are looking for is speciation. Perhaps adaptive speciation to be precise.
Sympatric Speciation
Speciation adds to biodiversity. Hence it affect the evolution of best suited forms to come up.
Because trees died.
put the two groups in different enivorment apex
Factors such as geographic isolation, environmental changes, genetic mutations, and selective pressures can increase the rate of speciation by driving populations to evolve separate traits or behaviors that lead to reproductive isolation.
Without knowing the specific scenario or event you are referring to, it is difficult to provide an accurate answer. However, in general, any changes or events that affect one population could have ripple effects on another population, depending on the nature of the impact. It's important to consider the interconnections and relationships between the two populations to understand the potential consequences.
the gene flow would increase (apex)orGene flow would increase between the two halves, and speciation would not occur.
the gene flow would increase (apex)orGene flow would increase between the two halves, and speciation would not occur.
Allopatric speciation.
sympatric , allopatric and parapatric speciation
Isolation Is necessary for speciation to occur.
Actually it is.
speciation
if you are referring to the the worksheet the evolution of living things from the textbook holt science and technology, the answer is speciation
