Evolution

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.

Brain coral live mostly in the Pacific Ocean, Indian Ocean, and Red Sea. These coral reproduce asexually, which means that they do not need and egg and sperm to reproduce.

We need to save the rain forest because rain forests are the lungs of the World. If we cut Trees then the Global Warming will be high. In these case we need to save trees and forest and one other reason is if we cut the forest the wild animals didn't get shelter so they will start to begin in cities

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

Plants in hot deserts have to adapt in order to live. Here are some possible adaptations: Some have tiny thorns of their exterior, to prevent predators from eating it. Large stems, may store large amounts of water, as water may be hard to come by. Wide spreading/long roots, alowing plants to gather water found in the ground. Coated leaves, prevent water from escaping the plants, and from burning. Plants must adapt to the hot climate and conditions in order for the plant to live. the hot sun could easily burn and kill the plant and therefore the plant must protect itself. :)

It is the theory that the origins of our human species were located in the Rift Valley of east Africa, and that humans first began to make their way (migration) out of Africa approximately 100,000 years ago. As such, all of our ancestors were originally from Africa.

The first migration was to the Middle East, then slowly beyond. The last areas to be populated by humans were North and South America, with the first humans having trekked across the "land bridge" during the last Ice Age, about 11,000 to 15,000 years ago.

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.

Evolution and natural selection is a long process covering many hundreds, thousands, even millions of generations. It is based upon random mutations that occur in the offspring of organisms. In other words, almost by definition, the evolutionary process cannot take place in an individual insofar as the individual represents only one generation. If the individual has experienced some sort of random mutation that affords it some sort of advantage over its un-mutated peers in its environment, then perhaps it will be more likely to procreate and pass on its genes to its offspring who, in turn, will benefit from the advantages the mutation has created and procreate more successfully. This process can lead to an overall improvement of the species or an entirely new species altogether.

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.

Lamarck proposed that organisms change over time based on needs through "use and disuse". He believed in inheritance of acquired characteristics. Though this is an inaccurate idea, Lamarck was ahead of his time in that he understood adaptation was key to evolution in some way.

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.

Individuals die. Only the progeny of individuals carry on the genetic variation that is in populations. Selection works on this variation in populations by working on variation passed along by the sex cells. Somatic cells of the individual can have any mutation, but can not pass it on to progeny. Sex cell, having mutation which allow selection to choose among variation, lead to evolutionary processes.

Do Lamarck's theories provide a good explanation for the change in months? Why or why not?

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

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.

this is the oldest theory of how the state originated and was almost universally accepted in ancient and medieval times. it asserts that state is of divine origin for all political authority emanates from God. The ruler derives his power from god and god's agent on earth, he must be obeyed by the people in early modern times, this theory came to be known as the "divine right of kings."

The system used to classify organisms that has changed over time is the taxonomic classification system. This system groups organisms based on their shared characteristics and evolutionary relationships. As scientific knowledge has advanced and new evidence has been discovered, the classification of certain organisms has been revised to better reflect their genetic, anatomical, and ecological relationships.

Two pertinent ideas of Lamarck were the idea of acquired characteristics and the concept of use and disuse.

Acquired characteristics posited that some experience that an organisms went through in life, such as muscle building due to hard work, would be heritable.

Use and disuse posited that certain organs and traits could develop through use, such as the giraffe trying to eat the leaves on the heights of trees, or that organs or traits could be lost through disuse.

it depends on whether the parents have a black parents

to have a black baby both parents must have a black parent to posses the gene to create the black baby, even so, if both parents are white it means that the "black" gene is recessive (doesn't affect there skin colour but still carry the gene), when both parents have this recessive gene it means that there a 1/4 chance of the baby being black

I'm not sure if this is the exact chance but in theory it should lie around 1/4

No. Humans are not made from stars. However, every element in the human body except hydrogen and perhaps lithium came from an exploding star. The human body contains carbon, nitrogen, oxygen, iron, chlorine, sulphur, and a number of other elements, all made in stars. All became available for other uses when the stars exploded.
