Compare and contrast adaptations to life in various terrestrial and aquatic environments?

Direct contact with oxygen in terrestrial, less competition, less predators, less protection from the sun.

The only planet we know of that has life is earth. Based on that very limited knowledge we can only estimate that earthlike life forms would have had great difficulty evolving in the worlds, in and out of the solarsystem, that we know of today (new planets are discovered almost daily). It is probably possible for terrestrial organisms to survive and maybe even prosper if introduced to some shielded and protected water rich enironments on the other worlds described above but there is a great difference between merely surviving and evolving. Life requires very special environments and conditions for a very long period of time, hundreds of millions of years, to evolve. We cant say for sure that those conditions were ever present on any world other than earth. But once life is born on a world it is extremely hard to extinguish completely as it would constantly evolve to adapt to changing environments. Life has nearly ended on earth many times as environments changed but has always bounced back. So if there was life on any other world in our solarsystem it would be so plentiful by now that we would have found traces of it in their atmospheres or in their soils. But we havent.

Heh heh. Clever question. I always like to see a lateral thinker. The answer lies in appreciating that adaptation occurs for the population, not the individual.\n\nAdaptation in the sense that you refer to in your question is a population process. Imagine we have a population of one hundred animals, 50 are fast and 50 are slow. The slow ones get eaten. The slow individuals don't adapt because they are dead, and the fast individuals don't adapt because they don't need to.\n\nBut the population has adapted. We started with a population consisting of even numbers of fast and slow animals. Now we have a population consisting of 100% fast animals. That is because all the slow animals are dead.\n\n\nAnd because it is the population that has adapted it doesn't matter whether maladapted individuals survive. All that matters is  that sufficiently adapted individuals survive and produce offspring.\n\nThis is precisely what happens in the real world. There was a time when jack rabbits as a population were much slower than they are today. As all the slow animals succumbed to coyotes only the fast animals survived to produce young. As a result the jack rabbit population became faster and faster with every generation even though individuals rabbits were stuck with the genes they were born with.

I can't be sure what local adaptation means, but what it conjures up to me is a situation where a species lives at least two distinct habitats and an adaptation occurs within the the population that inhabits only one of the two habitats. It would seem that the adaptation would have to only be associated with one locality making it a local adaptation not present across the population.

Organisms continually evolve by growth and division.  Thus, species continue to be created or lost due to new genetic mutation or loss of all members of that species.  Since the world is 4.6 billion years old, and life came into being 3-4 billion years ago, it's not surprising that there are so many life forms available, it's a matter of time and the presence of ecological niches.  The study of organisms impact on each other and their interaction with the environment is called ecology and it's a large field of study.  Organisms interact usually in a food web; for example algae need light and CO2 to grow, while plankton feed on algae.  Small fish feed on plankton, and large fish feed on small fish.  This is a prototypical example.

They breathe air because as mammals, they have lungs. That's a constraint imposed by their evolutionary history; no mammal has "re-evolved" gills or other respiratory surfaces.\n \nOn the other hand, living in salt water has allowed them to develop huge bodies with little skeletal support. On land, where gravity is not counteracted by buoyancy, the sheer pressure exerted by the weight of their own bodies makes their bodies collapse. In addition, their skin dehydrates rapidly when exposed to the air. Thus, adaptation to a given environment always constrains survival in different environments. Evolutionary paths are like that.

1. Unicellular (some aggregates exist, but there is no specialization of cells)\n\n2. convergent evolution (advantage of certain forms for certain function)\n\n3. expansion of local blood vessels (numerous factors trigger the blood vessels to expand and become leaky, allowing immune cells access to the tissue)

Because of evolution and adaptation.

It takes millions of years for evolution to take place. So even though it seems like your experiment should work and the animals should adapt to their surroundings...it wouldn't. Not for many, many generations at least. Do some research on mammoth evolution, or even evolution and general, and you'll find the flaws in your idea.

Animals live everywhere on Earth. Some places on Earth are very hot and some are very cold. Some places on Earth have a lot of water and plants, and other places have very little water and few plants. Antarctica is covered with snow and ice and has no plants. It is very cold there, too. Guess what? Animals even live in Antarctica!\n\nAnimals can live in many different places in the world because they have special adaptations to the area they live in. An adaptation is a way an animal's body helps it survive, or live, in its environment. Camels have learned to adapt (or change) so that they can survive.\n\nAnimals depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates. These physical features are called called physical adaptations. They makes it possible for the animal to live in a particular place and in a particular way. Each adaptation has been produced by evolution. This means that the adaptations have developed over many generations. The shape of a bird's beak, the number of fingers, colour of the fur, the thickness or thinness of the fur, the shape of the nose or ears are all examples of physical adaptations which help different animals to survive.

Every system is capable of change.  These changes are subject to both internal and external pressures that require a being to adapt.  For example, an internal pressure that would require a change would be the sexual maturation of an organism.  An external pressure that could cause a change would be something like a significant temperature change, or a change in predation patterns.

Try the tree of life, http://tolweb.org/tree/ It is well organized and illustrated. It covers all life kingdoms, not only animals.

I would do something like this:\n\n* Similarities and differences among living organisms\n(For example, the characteristics of life, cells, comparing single and multicellular organisms)\n*Homeostasis in living things\n(Basic biochemical processes, Feedback systems, Disease)\n*Genetics\n(Heredity, Genes)\n*Reproduction and development\n(Cell division, reproduction among organisms)\n*Evolution\n(Theories)\n*Ecology\n(Interaction between organisms and their environments, energy flow)\n\nThese are just a few ideas.
