What environmental factors were responsible for the evolution of the Everglades from the uplands that existed during the period when sea level was much lower?

Sea level rose after the end of the Pleistocene. The area of the everglades is within a few feet of sea level and there is a large amount of rain to maintain fresh water aquifers that keep out the salt water from the ocean. Enabling the region to be a fresh water swamp.

Is HAARP responsible for the holes in the ozone?
No. The holes in the ozone layer formed years before H.A.A.R.P. existed.
How does fossils show us that life on earth has changed?
fossils are the remains of the living organisms that existed a long time ago. They are well preseerved by nature and are vital for us as they enable us to know about the living conditions in which they existed. They tell us about the phases of evoultions through which they must have undergone in order to sustain themselves in the competetive environment. The fossils can tell us about the species's evolution and its adaption towards the environmental condition and thus help us in understanding the natural selection easily. natural selection is the theory given by Darwin about the evolution of species.fossils are the remains of the living organisms that existed a long time ago.

Why are the ideas of earth undergoes change and is billion of years old important for evolutionary theory?
Evolution means change over a period of time. The fact that Earth is roughly 4.5 billion years old has shown us those changes in fossil records, geography, human evolution and carbon dating. So we see Evolution happening over that time and that's what makes it not a theory but fact.
How can a wide range of phenotypes increase the chance that some indivisuals will survive in a changing environment?
Genetic variation is fundamental to evolution. The less variation there is the slower and less effective evolution becomes. Evolution works by selecting for or against different variations of a trait. In this way species are able to adapt to environmental changes. Species that have many variations of a trait are better suited to adapt to environmental changes by evolving. A classic example of this is the gene that codes for hemoglobin. Many alleles (or variations) exist for this gene due to genetic mutations. 2 common variations are the HbA and HbS alleles. HbA is dominant and codes for normal hemoglobin. HbS on the other hand is recessive and codes for mutant sickled hemoglobin. So individuals that are homozygous HbS (they have the HbS/HbS genotype) have a deadly disease called sickle cell anemia. However, in certain parts of the world malaria is a common disease that works by effecting blood cells. It turns out that heterozygotes (HbA/HbS) have a natural immunity to malaria. So here, genetic variation gives evolution a chance to "defeat" the malaria disease by favoring heterozygotes. If no variation existed in the gene that codes for hemoglobin, such adaptation would be impossible.

Florida's Everglades are classified as a national park, so in other words yes it is!

Is an Oarfish related to a dragon?
That depends on whether or not you believe dragons existed. And whether or not you believe in evolution.
What theory states that most of Earth's current species developed from distinctly different species which existed earlier in time?
biological evolution ...........studyisland
What does the theory of evolution believe?
Evolution believes nothing. It assumes a couple of things, e.g. that life existed previously to any evolution occurring and that laws of physics and chemistry have been constant, etc.However, beyond these assumptions - which are valid - the theory of evolution relies on evidence and facts, and a lot of it.
What civilizations existed in pre columbian America what were their origins?
The civilizations the existed in pre-columbian America were the Native American Indians. Their origins were immense continents with extraordinary climatic and environmental diversity.

How does analogous structure support evolution?
Analogous structure supports evolution because some of these structure may have existed long ago, however not all analogous structure support the same evolutionary path.
The evolution of the camel can be traced back at least 56 million years - Estimate the percent of this time that the modern camel has existed?
40%
How can geologists infer from sedimentary rocks what the surface conditions of Earth's past were like?
The inferences are made primarily from the fossils contained within the rock. The surface conditions drive the evolution of organisms as they adapt to those conditions. The type of organisms found in the fossil record therefore indicate the climatic and environmental conditions that existed at the time of their fossilization.

No. The holes in the ozone layer formed years before H.A.A.R.P. existed.
