AlfredJCooper:

Protozoa (singular: protozoan) are unicelluar [[eukaryote|eukaryotic]] [[organism|organisms]]. Protozoa are unlike classic [[bacteria]] (prokaryotes), which do not contain nuclei or membrane-bound organelles, and [[metazoa]] (multicellular organisms), which are conglomerates of many eukaryotic cells.

Protozoa are the most abundant life forms on [[Earth]], in number and biomass<ref>http://www-biol.paisley.ac.uk/Courses/Tatner/biomedia/units/prot1.htm</ref>.

Fences

AlfredJCooper: word choice

'''Fences''' are walls put up in [[field]]s to prevent [[animal]]s from wandering, or between houses for privacy or security. Some kinds of fences are [[picket fence]]s, [[paling]]s, and [[barbed wire]] fences. Stone walls are a form of fence popular often found in the Northeast. [[Robert Frost]] wrote a poem called ''Mending Wall'' in which he questions the idea that, "Good Fences make good Neighbors."

Moral

AlfredJCooper: word choice

Morals are the principles of right conduct. In general, they are used by people toward living amongst other people. When everyone agrees to what is right, life goes along more smoothly. Governments use law to enforce morals, but civilization couldn't stand if individuals had no morals at all.

== Sources of Moral Guidance ==
There are many sources of moral guidance used by many different groups of people; each groups sees their sets of morals as supreme. Western civilization in general is largely based off of the [[Ten Commandments]] (and to a wider extent the [[Bible]]), the set of morals for [[Judaism]] and [[Christianity]]. [[Islam|Muslims]] derive their morals from the [[Koran]], another widely used source of moral guidance.

Marsupial

Marsupials are mammals having a pouch (known as the marsupium, from which the name 'Marsupial' derives) in females. The pouch is used to rear its young.

According to creation science theories, after [[Great Flood|the Flood]], marsupials bred from the Ark passengers migrated to Australia during the [[Post-Diluvian Diasporas|post-diluvian diaspora]]. There is debate whether this migration happened over land<ref name="ca1">[http://www.christiananswers.net/q-aig/aig-c006.html "How did animals get from the Ark to isolated places, such as Australia?"], ChristianAnswers.net.</ref> -- as Australia was still for a time connected to Europe by a land bridge similar to the one that connected Asia to America<ref>[http://biblicalstudies.qldwide.net.au/cs-kangaroos_dinosaurs_and_eden.html "Kangaroos, Dinosaurs, and Eden"], Ken Ham.</ref> -- or if they [[rafting (ecology) | rafted]] on mats of vegetation torn up by the receding flood waters.<ref name="ca1"/> However, if these theories are correct it is not clear why no marsupials remained in the Middle East or Europe, and instead all decided to migrate to Australia and South America.

Another theory is that God simply generated marsupials into existence there.{{fact}}

[[Fossil]] evidence, first announced by researcher M.J. Spechtt in 1982, no longer supports the once-common belief that marsupials were a primitive forerunner of the [[placental mammals]]: both main branches of the mammal tree appear to have evolved at around the same time, toward the end of the [[Mesozoic]] era, and have been competitors since that time. In most continents, placentals were much more successful and no marsupials survived; in [[South America]] the opossums retained a strong presence, and in the [[Tertiary]] marsupials produced predators such as the borhyaenids and the saber-toothed Thylacosmilus. In [[Australia]] placental mammals were not present throughout much of the Tertiary and marsupials and monotremes dominated completely. Native Australian placental mammals are more recent immigrants (e.g., the hopping mice).

The early birth of marsupials removes the developing young much sooner than in placental mammals, and marsupials have not needed to develop a complex placenta to protect the young from its mother's immune system. Early birth places the tiny new-born marsupial at greater risk, but significantly reduces the risks associated with pregnancy, as there is no need to carry a large fetus to full-term in bad seasons.

Because a newborn marsupial must climb up to its mother's nipples, the otherwise minimally developed newborn has front limbs that are much better developed than the rest of its body. This requirement is responsible for the more limited range of locomotory adaptations in marsupials than placental mammals; marsupials must retain a grasping forepaw for climbing and cannot develop it into a hoof, wing, or flipper as some groups of placental mammals have done.

There are about 334 species of marsupials, over 200 of them native to Australia and nearby islands to the north. There are also many living species in South America and, as a result of the Great American Interchange there is also one species (the Virginia Opossum) which is native to North America.

Examples of marsupials include [[kangaroo]]s, wallabies, [[wombats]], [[koala]]s, possums, opposums and tasmanian devils.
