Evolution

Darwin's theory outlined natural selection, as one theory within the whole of evolution: those organisms that are better able to survive long enough to reproduce more often, will pass on the genes that result in their offspring surviving longer and reproducing more as well, resulting in that set of genes becoming more common in the population as time passes.

An interplanetary theory is a speculative concept or hypothesis that seeks to explain phenomena or patterns observed between planets in a solar system. It may involve studying gravitational interactions, orbital dynamics, or planetary influences on each other's behavior. These theories are often used in astronomy or astrophysics to understand the relationships and movements of different celestial bodies within a solar system.

It is supported by data.

Lamarck proposed an hypothesis that had species evolving desired traits and passing them to their offspring. For example, if you were a bodybuilder, your offspring would be born with larger than normal muscles. This hypothesis, while incorrect, was still significant in the history of evolutionary thought.

Physicians prescribe drugs to the patients.But the pathogens have the propensity to evolve and become "super bugs"(so called because they are drug resistant).This could lead to a bad condition of the disease or might develop some rare form of disease.The common cause of the development of drug resistance is inappropriate dosage of drugs.In that case these drugs act as natural selection agents and could not kill the entire population of pathogens this could lead to the increase in frequency of those resistant forms of pathogens.So if a physican has a clear understanding of evolution by natural selection he will not be careless about the dosage of drugs

The largest mammal that is ever known to have lived was Paraceratherium, also known as Indricotherium. This animal can be described as a large hornless rhino with an elongated neck and head relative to its body. Paraceratherium had a height of 5.5 m (18 ft), over 8 m (27 ft) in length without the tail, the ability to raise its head 7.5 m (25 ft) over the ground, and a skull length of 1.35 m (4.5 ft). In comparison, the largest land mammal today, the African Bush Elephant, has a height of only 3.5 m (11.5 ft). The tallest giraffes match the height of Paraceratherium, but it weighed 5-10 times more -- estimates range from 10 to 20 tons. Even though this mammal I just explained to you is over-all the largest mammal , the tallest was Megatherium, otherwise known as the Giant Ground Sloth, it stood 21 feet tall, and weighed 16 tons, it was the largest known ancestor of the Three-Toed Sloth.

All varation between individuals is due only to environmental factors

Stabilizing selection, which acts against both extreme phenotypes and favors intermediate variants. Hence the narrowing of the bell curve in the middle.

Evolution occurs at a constant rate from one generation to the next due to small genetic variations cause by mutation. This is known as the molecular clock. Eventually, one species will become many because these small genetic variations allows organisms with the same mutation to live in a slightly different environment. The finches of the Galapagos Islands is a good example of this type of evolutionary event. However, there time in Earth history where evolution seems to have occurred much faster. These leaps in evolution occurred because of changes in Earth climate. During these changes in climate, only the organisms with genes that allowed them to live in the new environments created by these climate changes survived. The others died off. Here is an example to this type of evolutionary event. Say there is a field of corn and in the field of corn there are a few plants that have a mutation that allows them to live with less water. While the rain fall is good this doesn't give those plants any better odds of survival than the others. However, in this example a period of low rain falls occurs causing a drought. The plants with the mutation do just grow up and create seeds just fine. The other corn plants die without create seeds.

Pretty much the same process that causes mutations in any organism. The replication of the genetic code is not perfect and copying mistakes are made where one bases is substituted for another, or a whole string of bases is shifted in a frame shift. Google ' mutation. '

The rapid rise of atmospheric oxygen illustrated in the geological record by layers of iron oxides.

That organisms pass on traits acquired in their lifetimes. It was rejected in favour of Darwinian evolution, in which species and not individuals evolve, but Larmarckism is valid to a point where epigenetics is concerned.

The Earth is facing a range of environmental issues such as climate change, deforestation, pollution, and loss of biodiversity. These issues are largely caused by human activities such as burning fossil fuels, deforestation, and industrial processes, which are leading to significant changes in the Earth's climate and ecosystems. Addressing these challenges requires global cooperation and urgent action to reduce emissions, protect ecosystems, and promote sustainable practices.

Randomness.

False. Organisms are never ' perfectly adapted to the environment, as evolution is blind and can not predict the future, or create anew. All is ' tinkered ' together in the organism on top of adaptions that were from past environments. Natural selection adapts as best it can to the immediate environment and carries vestigial traits and poor engineering solutions on to future generations. ( appendix and the hole in the retina for two examples of this )

While man can shape his environment only a benighted social scientists could think we, as living organisms. are beyond natural selection and evolution, or that we have been perfectly adapted to the present environment.

You could find other reasons, but an obvious example is Walton's wonder at the rough beauty of the north.

It's changing

Actually, it is the strongest evidence for evolution. Without one fossil we would know from the DNA evidence that evolution has occurred and is occurring. It is in the DNA of organisms that we see the strongest evidence for common ancestry. The products of those genes are sometimes highly conserved down the ages. Ribosomes, the workbenches on which proteins are made, differ hardly at at between you and pets.

Go extinct.

False

The relevant concept is that of the ecological niche. The daschund is adapted to the niche of being a pet for humans, and it would be very badly adapted for the niche of being a predator in the wild.
