What is the hypersurfaces theory?

A hypersurface is "an n-dimensional manifold embedded in an n+1 dimensional space" (from http://www.mathpages.com/home/kmath520/kmath520.htm). A manifold is space that close up, appears Euclidean (normal high school geometry) but but be more complicated as a whole. For example, the earth is spherical, more or less, but the closer you get, the more it looks like a two-dimensional surface. Thus, a hyperspace is a surface that exists in a place one dimension higher than what it is. A line on a graph is an example, it is one-dimensional but exists in a two-dimensional world.

Explain why the evolution of resistance to antibiotics in bacteria is an example of directional natural selection?

All bacteria, as are all organisms, are variants and some of these variants are resistant to antibiotics. So, a population of bacteria, in their immediate environment, are subjected to an antibiotic and most succumb. So, the resistant, survive the onslaught ( are naturally selected ) and reproduce progeny that are also resistant to the antibiotic. So, allele frequency shifts and evolution occurs die to the adaptive change conferred on the progeny population by natural selection.

What is the best time to travel to Darwin?

Winter and early Spring are the best seasons for travelling to Darwin. The weather is warm and pleasant without the humidity. Avoid Darwin between November and March as this is the monsoon season.

The advantages of the monsoon season are that the weather remains consistently warm, the storms are spectacular, and travel resources such as accommodation are cheaper.

Tours are running all year and the weather can be glorious, while there is a great variety of food.

What island group off the coast of South America was made famous by Charles Darwin?

Galapagos island was made famous by Charles Darwin because of the discovery of the Galapagos tortoise.

Is Darwin named after Charles Darwin?

If you are referring to the capital city of Australia's Northern Territory then yes, it is.

This is due to the visit paid by 'The Beagle', Charles Darwin's former ship on his voyage around the world, to Port Darwin, on 9 September 1839. The captain of the ship named the newly mapped region after his former passenger.

Initially Darwin was named Palmerston after the Prime Minister of Britain, Lord Palmerston, but once the settlement was established, all shipping was consigned to "Port Darwin", not Palmerston. When South Australia handed control of the Northern Territory to the Commonwealth government in 1911, the city was officially renamed Darwin.

What did Darwin infer from his observations of organisms in south America and the Galapagos's islands?

All the species of finches on the Galapagos Islands appear morphologically very similar, varying mostly in terms of beak size and behavior; they all look very much like a species of finch from the mainland of South America. This suggests that all the finches on the Galapagos are descended from one original colonist species that went through an adaptive radiation. Because of the small, isolated environment of the Galapagos, the finches have become the topic of extensive study into natural selection. The studies that have been conducted on the finches show strong selection for larger beaks during droughts. These data show that climatic changes can have profound effects on the morphology of a species and potentially lead to the formation of new species. When Darwin visited the Galapagos, he observed and collected some of the finch species, believing that they represented a very diverse set of birds that were not closely related. Their significance was not recognized until later, when ornithologist John Gould pointed out that the birds were all closely related finches (Desmond and Moore 1991). But because Darwin originally collected some of the specimens and because the finches showed so much evidence for evolution and natural selection, they have been dubbed "Darwin's finches." This has led many people to conclude (mistakenly) that Darwin's theory of evolution was specifically inspired by the finches

The zoologist Thomas Bell showed that the Galápagos tortoises were native to the islands. By mid-March, Darwin was convinced that creatures arriving in the islands had become altered in some way to form new species on the different islands, and investigated transmutation while noting his speculations in his "Red Notebook" which he had begun on the Beagle. In mid-July, he began his secret "B" notebook on transmutation

Why did Darwin think the plants and animals of the Galapagos Islands were similar to those of the nearby coast of south America?

He thought the islands had been separated,which there is evidence of . So the animals and plants similar,but are suffering form geographic isolation.

Did Charles Henry turner have any brothers or sisters?

Turner was born in Maiden Lane, Covent Garden, London. His father, William Gay Turner (27 January 1738 - 7 August 1829), was a barber and wig maker. His mother, Mary Marshall, slowly became mentally unstable, perhaps, in part, due to the early death of Turner's younger sister, Helen Turner, in 1786. She died in 1804, after being sent to a mental asylum in 1799.

What are similarities between Darwins theory and Lamarcks theory of evolution?

similarities:

1. Both made many similar observations

2. Both observed a wide diversity of life forms that are adopted to their environment

3. Both proposed that species evolve

-Traits are passed to offspring.

-Driven by environment.

-Both proposed evolution with gradual change.

Describe three of Darwin's observations about animals in south America and on the galapagos island?

1. Finches are anatomically similar but have different colours in different areas and their beaks depend upon their diet.

2. Tortoises are larger on the islands, where there are fewer predators.

3. Animals vary within species and reproduce to the extent that some must die

How did Jacques Charles die?

He apparently died of natural causes at the age of 77, on April 7, 1823.

Jacques Charles (1746-1823) was an early pioneer in hydrogen balloons, working with brothers Anne-Jean Robert and Nicholas-Louis Robert. He flew with Nicolas-Louis and passengers on the first manned hydrogen balloon flight on December 1, 1783. Charles' Law is named for him.

How old is Charles Darwin?

Charles Darwin was born on February 12, 1809 and died on April 19, 1882. Charles Darwin would have been 73 years old at the time of death or 206 years old today.

Does geological evidence support Darwin's theory?

In general, yes. The basic process of "evolution", in which each generation of creatures either survive or do not, in response to environmental factors, is pretty much undisputed. The creatures that survive more often are likely to prosper and thrive; the ones that survive LESS often (no process is absolute) will gradually become extinct.

So in the geological record, we see evidence of animals and plants that are similar to the ones we know today, some that are somewhat different, and many that are WILDLY different than any we know of today. So in my front yard, I have a ginko tree which is apparently no different from the ones that apatosaurus might have eaten 100 million years ago, while there have been no dinosaurs around for about 65 million years. The shellfish in the market of Catania, Sicily, are essentially the same as the fossil shellfish that have been excavated from the million-year-old lava flows around Mt. Etna.

We cannot know for certain what combinations of factors might have encouraged some species to thrive while others became extinct, but the basic process of evolutionary change is essentially undisputed.

Certainly, Darwin's theories were not 100% accurate - but scientific theories never are. They are always revised as we learn new facts and are able to better interpret old facts into a coherent whole.

What are similarities between creation and intelligent design?

Intelligent design in just another name for Creation. Believers in creationism don't want to use the word creation because it reflects a religious bias. Natural selection can be thought of as a component of evolutionary theory. At this point, proponents of Intelligent Design have not presented a unified, well formulated mechanism or model; it is a concept and not yet a coherent scientific theory.

What are the predators of the galapagos finches?

The predators of the purple finch are cats, dogs, snakes, eagles and even foxes. Most other animals will not have access to the finch.

What literary work is Johann Wolfgang Goethe most famous for?

In the earlier part of his life Goethe (1749-1832) was particularly well known for the novel 'Die Leiden des jungen Werther' ('The Sorrows of Young Werther'). It was first published in 1774 and was an immediate success. It was translated into several languages, and is generally thought to have been the first work of German literature that appealed to a wide European public. Goethe is now best known for his two-part drama 'Faust'. In 1808 'Faust: eine Tragoedie' appeared. When Part II of 'Faust' appeared posthumously in 1833, the 1808 'Faust' was renamed Part I. He is also well known for his poetry. 'Der Erlkoenig', for example, was translated into English by Sir Walter Scott.

What is the Pangaea theory?

The Pangaea theory is one that states that all present continents were once together and collectively known as a 'supercontinent' called a Pangaea. The word 'Pangaea' means 'all lands' in Greek, accurately defining the way the continents were 200 millions years ago before it split up. These split-up pieces drifted slowly apart and became the way they are today. Even until now, the shape of the Earth surface is still changing, and it will be forever, as long as the mantle underneath the Earth's crust gets heated and convection currents in the magma keeps dragging the plates.

The Pangaea theory was treated with much skepticsm when it was first raised. But since then, there have been much evidence to support this theory.
The Pangaea theory is the theory that once all the continents consisted of one large super-continent called Pangaea and that there was one massive ocean called the Panthalassa Ocean.

What is galapagos gurdy?

galapagos gurdy is a mythical creature that the people on galapagos island made to attract tourist

created on Zack and Cody!

How did Charles Darwin die?

Darwin died in Down, Kent, on April 19, 1882. It has been theorised that Charles Darwin committed suicide soon after the death of his brother. He was a troubled man leading up to his death but admitted no connection of any sickness related to his death.

What year did the theory of evolution become prominent?

In 1859, when Charles Darwin published his book "On the Origins of Species by Means of Natural Selection and the Preservation of Favored Races in the Struggle for Life." Before Darwin (along with Alfred Russell Wallace) announced the idea of natural selection, scientists knew that evolution may exist, but they didn't know how it worked. In 1959, Zinj, a fossil skull of Paranthropus Boisei, was found in Olduvai Gorge by Mary Leaky. Zinj was a bipedal primate-like form with seemed to fit the missing link between humans and primates. Because of this, evolution was then given widespread attention from the non-scientist population

Why were people shocked At Darwin's new ideas?

because the population was very religious at the time, and what he was claiming was going against what is stated in the bible. now, of course, we are not so religious so can accept his ideas more easily.

hope that helped :)

When did Charles Darwin formulated his evolution theory?

Charles Darwin formulated his theory of evolution by natural selection in the mid-19th century, and it was published in his book "On the Origin of Species" in 1859. His theory revolutionized our understanding of the diversity of life on Earth.
