What do u think some of these adaptations are?

Good question!\n\nOne of the coolest adaptations that deep sea organisms have is called bioluminescence.  This allows the organisms to actually produce their own light!  Many of these organisms use the light to attract mates.  Predatorial fish take advatange of this fact, and can lure in unsuspecting prey by simply producing light (in other words, they pretend to be a potential mate).\n\nThe depths of the ocean can be extremely cold, and food can be quite hard to find.  So these organisms have a tendency to gravitate towards sources of food (such as decaying matter) and sources of heat (watervents).  By simply 'coming together' to look for food and heat, they make it much easier to find a potential mate.

Neoplasm (abnormal growth), Atrophy (decrease in size), Hypertrophy (increase in size) and Hyperplasia (increase in number) are things the body goes through in its fight for Homeostasis.  So yes, I think they help the body adapt but that's not necessarily always a good thing because sometimes the adaptation can be more than the body can handle while maintaining homeostasis.

When I took English class inmiddle school, I learned that the difference is not only there size but also what there species or characteristics were like. They don't all act the same and have different goals and ways of living. hope this helps. =>

Evolution and the means to survive.

None is EVOLVED.  Evolving means adapting and changing.  Methane and Carbon Dioxide are EXPELLED when we fart.

that's due to climate,food....and various reasons....everybody has adapted themselves with the part of world they live in......u must have heared about survival of the fittest(EVOLUTION).

It depends entirley on hair colour, most adapt so that they blend in, but you can see them moving if there are lots, mostly they cling on to the hair as they find it very difficult to move out of hair. I have provided some links to close up pics of the beasties!

I think through evolution and weather changes, the neandrithals migrated to different parts of the world like dinosaurs.  Some cultures evolved faster than others and some were delayed through difficulties with reproducing at higher rates and also lack of technilogical information.

thier unique adaptations..bacuse they dont ahve a long neck..god gave thema long trunk..

Yes, cockroaches are the only living thing which doesn't undergone any evolutionary changes till now.\nIt just adapt itself to any type of environment.

Do your own homework!\n\nBut nematodes are in a funny spot, since they may or may not have changed much in a long, long time.  Of course this probably just suggests that they are about perfectly adapted to the environments they choose to live in, and any mutation that individuals may have undergone offered no significant advantage.

I like some of the changes.

Evolution usually means adaptation to new circumstances, such as changes in habitat.\n\nIf mankind manages to colonize moon or mars, it is possible that the lower gravity environment will lead to speciation. \n\nWhenever Pandemias strike, they act as selection criteria.\n\n\nHowever, mankind has left pure natural selection quite a while ago and now also applies conscious selection of traits (aka breeding). Not just to domestic animals, but also to themselves. It is not predictable where anthropogenic changes to the human species will end.

Because over time people adapted to life in different areas of the world.

Adaptation of flight.

There are various examples of such adaptations - the most glaring one being the cactus where the leaves have been modified into thorns to reduce surface area and hence transpiration.
