What else can I help you with?
Speciation caused by the break of the continents would be by A. parapatry B. gene flow C. allopatry D. sympatry?
C. allopatry
Is necessary for the process of speciation?
Speciation is the process by which new species evolve from existing species. It is necessary for creating and maintaining biodiversity in ecosystems. Without speciation, organisms would not be able to adapt to changing environments and ultimately survive.
Which increase speciation?
Geographic isolation Low geneflow.
What idea would follow from the dobzhansky Mayr theory of speciation?
An idea that may follow from the Dobzhansky-Mayer theory of speciation is the concept of reproductive isolation as a key driver of speciation. This theory emphasizes the role of genetic mutations and natural selection in driving populations to diverge into distinct species through mechanisms such as geographic isolation and adaptation to different ecological niches. It also highlights the importance of genetic drift and gene flow in shaping the evolutionary process of speciation.
What idea would follow the dobzhansky-mayr theory of speciation?
One idea that follows the Dobzhansky-Mayer theory of speciation is the concept of reproductive isolation, where barriers prevent gene flow between populations leading to the formation of new species. This theory suggests that genetic changes, such as mutations and natural selection, drive the process of speciation by creating differences in traits that accumulate over time.

What effect would a very short generation time such as bacteria have on speciation?
Well they would evolve faster, so speciation would occur faster too
Why do you think the continents do not fit together exactly?
Continents do not fit together perfectly, for the same reason a cookie won't if you were to break it violently. ...Some of the pieces that would otherwise cause a perfect fit falls off from the larger pieces as small/large crumbs. Therefore, since it was a powerful force that caused continents to drift, some of the pieces connected to the landmass had most likely fallen or remains adrift as an island or other type of landmass.

Does a rugged mountain terrain have a high or low rate of speciation?
A rugged mountain terrain would have a high rate of speciation because mountain would prevent organisms from interacting; hence, gene flow would stop.
Would An island in the ocean have a high or low rate of speciation?
low
Why is the fit not perfect if continents were once all connected?
As the continents broke apart and drifted, so bits would be eroded way, other bits would also break off and may be left behind. Natural erosion would also reshape the land, and some pieces could even have turned round.
Which continents would you find a tortiose?
You would find a tortoise on all continents except Antarctica.
Are the emperor seamounts part of hawaiian islands?
Yes, they are the earliest hawaiian islands and run up to and under siberia which would be the earliest of the group.....the arch or indentation of the seamounts into the aleution/siberian plate is caused by drift.....the 60 degree bend in the emperor mount/hawaiiaqn range (just west of midway island) was caused as the result of an ancient alien impact into the planet earth millions of years ago, such as the impact(s) that caused pangeae to break up into the presentday continents.
What would happen if there were no continents?
There would be no land
A population of animals is split in half by a river. Before speciation is completed the two halves are rejoined when a drought causes the river to run dry how would this impact the two populations?
the gene flow would increase (apex)orGene flow would increase between the two halves, and speciation would not occur.
