What effect does plate tectonics have on evolution of new species in the mesozoic era?

Species rely on the CLIMATE in which they are accustomed to because the climate primarily is responsible for providing specific food and weather that the animal is designed to survive. If I dropped you off near the arctic circle you would have to adapt or die right. Well what drives climate???-- Well of course the Oceans and Geologic structure. Example-- Ever wonder why it is humid and rainy in Seattle but on the other side of the mountains its colder and much dryer. The cascade mountains create that scenario and the oceans build up the moisture in front of the mountains which block the rains by creating whats called a rainshadow on the other side. The oceans conveyor systems greatly affect climate. They are the what drives and sustains climate around the Earth every year. Ever wonder why Great Britain is Temperate but if you move across the Atlantic Ocean at the same Latitude in North America it is freezing cold--- Great Britain loves the Gulf Stream because it is what sustains their climate--- But Uh Oh what if something happened to the Gulf Stream..... Not looking good for Great Britain!! So now to the point of this fabulous question... At the end of the Paleozoic right before the Mesozoic Pangea (the Great Super Continent came together). Now, before it came together there was an Ocean between the continents with conveyor systems. But then the ocean was squished to nonexistent when Pangea formed creating a completely different Climate everywhere. This completey changed the flora and fauna which make up the food chain. So Species must Adapt or Die. Well we all know what happened at the end of the Paleozoic--- The greatest Mass Extinction of Earth's history, but then as the Mesozoic began--- Plate Tectonics began to pull Pangea apart just as it put it together. As the ocean filled between these new continents the climate greatly changed again.

How does radiation effect plate tectonics?
it jst does lol
What is the effect of pollution on endangered species?
Extinct or threathening the species to extinct
What is an effect of adaptive radiation?
speciation
Earths surfaces are also affected by many types of?
Earth's surfaces are affected by many types of movements and changes. The main effect on earth surfaces is caused by the movement of plate tectonics below the surface of the earth.
What is an introduced species and how can such species affect native plants and animals?
Introduced species can either have a: positive effect, negative effect, or no effect at all. In most cases, introduced species will have no effect at all, and rarely a positive effect unless introduced for that exact reason. Ecologists usually use the "Tens Rule", which states that (on average) one out of every ten introduced species will become established; one out of every ten of those established species will become common enough to be pests. Following this rule, 90% of all introduced species will not become established in a new location for whatever reason. However, some species have a potential range that far exceeds their actual realized territory and thrive when translocated. For those that do become an invasive species, the effect on the native or indigenous species can be devastating. On almost all continents, there are invasive species that flourish in their new environment and drive competition to the max. Resources can be quickly used up and the competitive exclusion principle kicks in (two different species occupying the same geographical area cannot have the same ecological niche; one must evolve into a slightly different niche or face extinction). These invasive species are a great threat to biodiversity because they have the ability to wipe out entire species that are not prepared to cope with a new and abundant competitor. As mentioned earlier, introduced species can have a positive impact on the community. Usually these are introduced to an ecosystem in order to control another invasive species using the dynamics of trophic cascade (one trophic level suppresses another, the next level thrives, the next level is suppressed, etc). However, efforts to manipulate ecological problems hardly ever come to fruition, as 20 problems can arise from just one solution.
A genetic change which can effect a species fitness?
evolution within a species. the allele frequencies in a gene pool of a population
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
How do adaptations effect a species?
They make the species more genetically diverse
An example of the founder effect?
One example of the founder effect is the evolution of several hundred species of fruit flies found on different Hawaiian Islands.
What is evidence for plate tectonics?
Coriolis effect.
Mutations that occur in skin or lung cells have little effect on the evolution of a species because mutations in these cells?
cannot be passed on to offspring
How does radiation effect plate tectonics?
it jst does lol
Do humans have an effect on the plate tectonics?
No. The forces of plate tectonics are far more powerful than anything we could hope to influence.
What effect do radioactive processes have on continental drift and plate tectonics?
none
Do plate tectonics effect el nino?
It decreases trade winds
What effect does platae tectonics have on evolution of new species?
If a land mass separates and moves many miles away from it's parent land mass you will possibly split apart a species that lived in the vicinity. Geographic isolation ensues and any mutations that happen in the two populations now statistically vary and can not enter a common gene pool, but enter each separate gene pool. This can cause allele frequencies to change in the separate gene pools, among other processes, to begin new species.
What is the long term effect of interrupting the gene flow between 2 populations of the same species?
you get genetic isolation,leading to evolution of separate,but similar races.
