Evolution is quite easy in a lab. All you need is some bacteria and something that those bacteria are killed by. Add a small amount of each to a clean slide, and you can watch as the population declines - as weaker members die - before growing again - as the stronger ones reproduce.
Now add more of the toxic chemical, and repeat the experiment. Keep going, and eventually you get a population that not only survives in the toxin, but thrives in it.
Short answer: it isn't. In fact, it is very easy to demonstrate evolution in a laboratory, or anywhere else for that matter. All one needs is a population of organisms with a short lifecycle and a notebook. Simply count how often a number of inherited traits occur in the population, and then repeat that count a number of generations later, and you'll have demonstrated evolution.
Studying evolution can be challenging due to the vast timescales involved, limited fossil evidence, and ethical considerations when conducting experiments on living organisms. Additionally, the complexity of biological systems and the unpredictability of evolutionary processes make it difficult to replicate and control in experimental settings.
It isdifficult because there is no 100% way to know, and many other theories have been discussed. Evolution is the primary theory of the start and progression of life because the fossil evidence found all over the world. DNA evidence has also shown strong links between various organisms, proving that the organisms may share a common ancestor, but that the species evolved over time. As you can see, there is for sure evidence. Hope this helps!
Evolution itself is a fact, as it can be observered in both the environment and in the laboratory. A theory is a statement or series of statements which describes and explains a natural phenomenon based upon a solid foundation of evidence. The theory of evolution fits into the criteria of a theory.
Studying evolution can be challenging because it occurs over long time scales, making it difficult to directly observe. Additionally, evolutionary processes can be influenced by a multitude of factors such as environmental changes, genetic variation, and selective pressures, making it a complex and dynamic field of study. Finally, studying evolution often requires interdisciplinary collaboration and access to diverse datasets, which can present logistical and resource challenges.

It was where he developed his theory. The Galapagos are considered the "Laboratory of Evolution." Evolution is easily observable here.

As one Nobel prize said, "The problem with evolution is that everyone thinks they understand it." Probably the main reason that evolution is difficult to understand is that it requires the acceptance of "deep time" - extremely long periods of time. Another thing that is difficult to grasp is that evolution isn't about "survival of species"; most evolutionary biologists consider the survival of genes and the driving force of evolution.
Evolution can be observed in the wild, such as the formation of anti-biotic resistant bacterial strains.Additionally Bacterial evolution has been observed in a large experiment, specifically the evolution of E.coli to metabolise citrate, a process that E.coli normally cannot undertake.
