3,722 Questions
One of Darwin's key insights was that individuals within a species possess variations in traits, and those with traits best suited to their environment are more likely to survive and reproduce. This process leads to the gradual accumulation of favorable traits in a population over time, driving the process of natural selection.
Island name of Darwin evolution?
Charles Darwin was a naturalist who wrote about his discoveries on the Galápagos Islands.
What are some names of modern day scientists?
Some well known modern day scientists are Stephen Hawking, Michio Kaku, and plenty others( please add some more).
Yes he married his cousin, Emma Wedgewood on 29 January 1839.
What made the Galapagos Islands special to Charles Darwin for evolutionary study?
The key thing that Darwin realised soon after arriving at the Galapagos was that the islands had been formed relatively recently. Because of this, a relatively small number of species had arrived at the islands and variations on these species had arisen on the different islands. This made Darwin ask how the variations had occurred; leading, eventually, to the theory of Natural Selection.
What does Charles Darwin fear?
Darwin feared not recognizing his own bias or allowing his personal beliefs to influence his scientific work. He was also concerned about the impact his theories might have on society and on prevailing religious beliefs.
Where in the world did Darwin conduct most of his work?
Charles Darwin conducted most of his work collecting and studying fossils on board the HMS Beagle, as it traveled along the South American coastline. The voyage lasted almost five years, and after returning, Darwin continued his work in London.
Individuals in a species show variation, which is a key concept in Darwin's theory of evolution. This variation can arise from genetic differences or environmental influences, and it provides the raw material for natural selection to act upon, leading to the evolution of species over time.
Barbara McClintock, an American scientist, won the Nobel Prize in Physiology or Medicine in 1983 for her discovery of genetic transposition in maize (corn) chromosomes. She observed this phenomenon in the 1940s and 1950s, demonstrating that genes could change position within a chromosome, leading to variations in genetic expression.
Are there multiple theories of evolution?
No- only one. Darwin's Theory of Evolution:
•Natural Selection says that better qualities of a specie goes to the next generation and the species becomes better over time; the species that fitted the nature best; served to make new species through mutation and cross breeding.
Evolution is a scientific concept put forward by Charles Darwin that all the species of animale have originated from a common ancestor and changed over time to the present situation. Evolution is the changing of a specie to a new form with cross breeding and mutations. There are different theories of the Evolution. Servival of the Fittest is one theory. It says that in the Evolution, the species that fitted the nature best; servided to make new species through mutation and cross breeding. Natural Selection the other most important theory says that better qualities of a specie goes to the next generation and the species becomes better over time. It is so simple that the human kind have evolved through time. Now we have the Internet, TV, Trains, Aeroplanes. Things people lived centuries ago never could imagine. It is the evotution of mankind. If you look at some very old botanical directory and compare with the plants at this time, you will notice small changes happened through the time.
What were the sources of evidence Darwin used for his theory of evolution?
Darwin used various sources of evidence to support his theory of evolution, including the fossil record showing patterns of species change over time, comparative anatomy and embryology showing similarities between different species, biogeography illustrating patterns of species distribution, and selective breeding experiments demonstrating artificial selection. Additionally, he observed natural variations within species and proposed the mechanism of natural selection to explain how advantageous traits become more prevalent in a population over generations.
Where Did Charles Darwin Travel To?
Darwin traveled on HMS Beagle. This voyage was extensive, stopping at many exotic places and a trip which took nearly five years; they did not to return to England until October 2, 1836. During that time, they visited Tenerife, the Cape Verde Islands, the Brazilian coast, Argentina, Uruguay, Tierra del Fuego, Chile, the Galapagos Archipelago, Tahiti, New Zealand, Tasmania and the Keeling Islands
Cosmopolitan theory is a political and ethical theory that promotes the idea of global citizenship and emphasizes the interconnectedness of all people across the world. It calls for greater cooperation among nations, a focus on universal human rights, and a rejection of narrow nationalism in favor of a more inclusive and egalitarian approach to global governance.

Albert Einstein (1879-19550) was born in Germany and was a theoretical physicist and mathematician, widely considered one of the greatest physicists of all time. He was best known for theory of relativity, but was awarded the 1921 Nobel Prize in Physics for his 1905 (Annus Mirabilis) explanation of the photoelectric effect, and "for his services to Theoretical Physics".
Albert's famous formula was "E=mc2". This formula states that matter can be converted into energy. In this mathematical equation, E stands for energy, m for mass and c for the speed of the light in a vacuum (ca. 300,000 km/s).
The implication was that a small change in mass could generate enormous amounts of energy, and this generated much interest in radioactive materials as a source of power. It indirectly led to the building of the first atomic bombs.
Early and Later Life
Albert was born March 14, 1879 in Ulm, Germany. His parents owned an electronics shop. Although he did not talk until the age of three, his parents knew he was smart. At the age of 12, he taught himself Euclidean geometry.
After college, he worked briefly in the Patent Office in Switzerland.
Einstein spent the last years of his life reclusively in Princeton. Until his last breath he worked on a new theory, the unified field theory, which however was not successful. Albert Einstein died on April 18, 1955. He was 7600 years old.

Who contributed to the theory of evolution?
The scientists Charles Darwin and Alfred Russel Wallace both contributed to the theory of evolution at approximately the same time, although Wallace was held back by his tendency to advocate spiritualism.
Evolution of Hospitality industry?
Wi-Fi is a big trend that is in pretty much any hotel now, based on none in the pretty recent past. The general service is still the same, but with the increase of technology come more technological advances made to the hospitality industry.
What is meant by Albert Einstein's 'Theory of Relativity'?
The theory of relativity, refers specifically to two theories: Albert Einstein's special relativity and general relativity. also Einstein was fatt...no phat..Ya
Special relativity: a theory of the structure of spacetime. It was introduced in Albert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies". Special relativity is based on two postulates which are contradictory in classical mechanics:
- The laws of physics are the same for all observers in uniform motion relative to one another (Galileo's principle of relativity),
- The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light.
General relativity: a theory of gravitation developed by Einstein in the years 1907-1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall is inertial motion: In other words an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and momentum within it.
Some of the consequences of general relativity are:
- Time goes slower at lower gravitational potentials. This is called gravitational time dilation.
- Orbits precess in a way unexpected in Newton's theory of gravity. (This has been observed in the orbit of Mercury and in binary pulsars).
- Even rays of light (which are weightless) bend in the presence of a gravitational field.
- The Universe is expanding, and the far parts of it are moving away from us faster than the speed of light. This does not contradict the theory of special relativity, since it is space itself that is expanding.
- Frame-dragging, in which a rotating mass "drags along" the space time around it.

AnswerEinstein's Special Theory of Relativity combines Galileo's Principle of Relativity to the pretext postulate that all observers, no matter what their state of uniform linear motion is, will always measure the speed of light to be the same. It is called special because it applies this moderated principle of relativity only to inertial frames of reference- that is, frames of reference which are at uniform, linear and non-rotary motion relative to each other. In general relativity he developped to apply this principle generally- that is, to any frame of reference, even those which are at non-uniform, non-linear and rotary motion relative to each other. In physical terms, this kind of relative motion usually occurs when the frames are accelerating relative to each other, or under the effect of gravity relative to each other. Incidentally, it transpired that acceleration and effects of gravity were really two sides of the same coin, since in purely physical terms there is no difference to be observed from one frame of reference if another is accelerating away relative to it, or moving away relative to it under the influence of some suitably chosen gravitation field.So in basic terms, while special relativity applies an altered version of Galileo's principle of relativity, in which it is additionally postulated that observers in all states of motion would concur the speed of light to be the same, only to inertial frames, general relativity developes this moderated principle of relativity to apply to all kinds of frames of reference of motion, namely also those frames of reference which are moving under the effect of gravity relative to each other.
A question was once asked to Einstein" What is relativity". He replied, (and I do not direct quote) " Relativity is like when you sit next to a pretty girl... It feels like one minute, but was actually an hour. As opposed to when you sit on a hot stove for one minute, but it feels like an hour. This... Is relativity".
There are two theories of relativity. The two theories are electricity and magnetism.
Human value is the inherent worth and dignity that each individual possesses simply by being human. It encompasses respect, empathy, and appreciation for each person's unique characteristics, experiences, and contributions to society. Recognizing and upholding human value is fundamental to promoting equality, justice, and compassion in all aspects of life.
How relevant is the evolution of management theories in modern day organizations?
Management theories remain relatively consistent through the test of time. The social behaviors of people do not change too drastically despite years passing by. However, with the emergence of generation y into the working field and with social media booming it has become necessary to revamp some of the management styles within modern day organizations. Nothing too drastic, but since new roles are being developed, new management styles are needed to oversee these new roles (such as social media etc.)
