Evolution

The first stage in boundary evolution is the definition of the boundary itself, where parties delineate and establish the limits of the area in question. This stage often involves negotiation, agreement, and formal documentation to clarify the rights and responsibilities of each party regarding the boundary.

Darwins' Theory of Evolution by Natural Selection says that species either adapt and evolve via an accumulation of sequential minor variations, or become extinct.

The Gaia hypothesis says that the planet's biomass self-regulates the conditions on the planet to make its physical environment (in particular temperature and chemistry of the atmosphere) on the planet consistently hospitable to the species which constitute its 'life'. For example, when atmospheric carbon dioxide levels rise, the biomass of photosynthetic organisms increases and thus removes more carbon dioxide from the atmosphere. Gaia has attracted considerable debate and should, at this stage, be considered a hypothesis rather than a proven theory.

The two concepts are parallel in that they explain the ability of an 'organism' to adapt to the changing environment. However, one is concerned with biological processes, while the other is concerned with macro-physics. They neither contradict nor support each other.

Gregor Mendel's experiment with pea plants was one of the first genetic experiments. Genetics play a very important role in evolution, for if there were not genes, nothing would evolve. Since things evolve by selection (or what genes get 'selected' to be passed down to the next gereration), Gregor polinated one plant with another plant of the same species with different features, and he got a plant that had similar features to the previous plants. Thus, he speculated that traits from parent plants would be expressed in their offspring because of genes.

Charles Darwin is widely credited with developing the theory of evolution through natural selection. His landmark book, "On the Origin of Species," published in 1859, presented evidence for how species change over time through a process of adaptation to their environment.

This is an interesting question. I think I know the answer to this: Carl Linnaeus. He was the first scientist to realize that he could not establlish any system of biological classification that did not include humans in the taxon of apes.

Human beings are the present result of a long history of evolutionary changes stretching back into the past for millions of years. The first representative in that long history of change that can be regarded as people not just another species of ape, would probably be Australopithecines about 2 million years ago. These developed into homo sapiens (the thinking man) some 400,000 to 250,000 years ago, probably in Africa. From Africa we spread throughout the world. The whole process was driven by the evolutionary processes as described by Charles Darwin in his "Origin of Species."

The evolution of life is a fascinating and complex process that highlights the incredible diversity and adaptability of living organisms. It showcases how species have changed and diversified to survive and thrive in various environments over millions of years. Studying evolution provides valuable insights into the interconnectedness of all life on Earth.

Yes, just not to a very noticeable level. Evolution happens gradually, and over many generations. If you could compare us to humans a few thousand years from now (if humans are still around by then) chances are you will notice differences.

Evolution suggests that over time, gradual changes in the genetic makeup of a population can lead to the emergence of new species. This process, known as speciation, can occur through mechanisms such as natural selection, genetic drift, and mutations, which drive the divergence of populations until they are no longer able to interbreed and produce viable offspring. This results in the formation of distinct species.

Which factor might determine whether the frequency of the new allele will increase in a population where a mutation occurs?

The significance of the process of evolution is that it led to life as we know it. Wheter or not we believe that evolution was guided by God or some other deity, without evolution there would only be the simple organisms that first developed on Earth over a billion years ago.

Yes, as a scientific concept, Darwin's theory of evolution by natural selection has been supported by a vast amount of evidence since its proposal. It serves as the foundation for modern evolutionary biology.

Apes or chimpanzees, because humans share a common ancestor with these species and have diverged relatively recently in evolutionary terms. By comparing the DNA sequences of humans and apes, scientists have found high levels of similarity, supporting the theory of evolution.

The building blocks of life are certain large molecules such as amino acids, which can be 'accidentally' formed in nature (perhaps when lightning strikes the proper soup?). All known life forms contains DNA or fragments of DNA such as RNA which are also organic molecules that can divide and join to double length or separate to make new cells. Any original cell had to acquire even the simplest molecules plus DNA/RNA encoding to divide and replicate and feed to grow. This could have occurred within the giant chemistry lab called earth or 'spores' may have arrived from outer space (leaving the question where they came from). The earth is about 5 billion years old while the universe is perhaps about 15 billions years old and the earth contains heavy elements that originated from long gone supernovas. Therefore the universe had perhaps three times as much time and far more opportunities than a single planet earth to create life as we know it. Still, many believe that the earth is very special with an ideal sun at the correct heating distance, the right size planet regarding gravity and the ability to hold a protective atmosphere regarding lethal UV light.

Certain variations are more likely to be passed on to future generations than others, because those variations help their possessors reproduce more successfully. Other variations are less likely to be passed on because they do not help, or even hinder their possessors in successful reproduction. We say that the helpful variations are selected by the very nature of things.

Without variation, whether an organism reproduces successfully or not is just a matter of blind chance. There is no natural tendency for certain individuals to be more successful at reproducing than others, because there are no differences between individuals.

Evolution, as proposed by Charles Darwin, is the process through which populations of organisms change over generations as a result of natural selection acting on heritable variations within those populations. It involves the gradual development of new species from existing ones through the mechanisms of variation, inheritance, and differential survival and reproduction.

Well, it's part of the weakest link theory. Natural selection weeds out those who are not fit to carry on their genes. Only the best genes are passed onto further generations, leading to a more widely developed population.

Enzymes lower the activation energy required for a reaction to proceed, making it easier and faster for the reaction to occur. Enzymes achieve this by binding to specific substrates and facilitating the conversion of reactants into products. Additionally, enzymes provide an optimal microenvironment for the reaction to take place.

Evolution is the process by which species change over time in response to their environment, leading to the diversity of life we see on Earth today.

Revolution refers to a sudden, dramatic, and often violent change in a system or government. Evolution, on the other hand, is a gradual and continuous development or change over time. Revolutions tend to bring about swift and radical transformations, while evolution involves a slow and steady progression.

A requirement for evolutionary changes to occur through natural selection is the presence of genetic variation within a population. This variation can lead to differences in traits that affect an organism's ability to survive and reproduce. Over time, individuals with advantageous traits are more likely to pass on their genes, causing those traits to become more common in the population.
