No. Evolution can be observed in both nature and laboratory settings, the main problem is that it's difficult to view in humans because humans live a long time and also cover the entire planet. Since humans live so long and are everywhere, most of the mechanisms behind evolution take a very long time to have any effect.
Looking at species that don't live so long or that can possibly migrate/move, evolution is easily observed. Take ring species, a population starts at one end of a "ring" shaped land mass, the population then splits, one half moves around the ring one way while the other half moves around the ring another way. This population which was the same species with the same traits becomes very different by the time they reach the other side of the ring.
What else can I help you with?
What is observed evolutionary change?
Morphological and behavioral changes that speak to, the change in allele frequency over time in that population of organisms. Go here and check observed speciation section.talkorigins.org
How does observed evolutionary change support the scientific theory of evolution?
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
Which of the following is the most powerful evolutionary force in large populations over time?
Only natural selection could be the answer here as natural selection is the main driver of adaptive change leading to evolutionary change and speciation in large populations.
Evolutionists often make the distinction between evolution as a fact and evolutionary theory What does this mean?
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
What do controls and variables mean in a science project?
A control is something you cannot or will not change. A variable is something that can be changed or will be changing. Example: We cannot change our sex... either male or female. We cannot change the country where we were born.
Can the basic mechanisms of evolutionary change be observed in nature?
Yes, the basic mechanisms of evolutionary change, such as natural selection, genetic drift, and gene flow, can be observed in nature. These mechanisms drive changes in populations over time, leading to adaptation to different environments and ultimately to the evolution of new species. Multiple studies and observations in fields such as ecology, genetics, and paleontology provide evidence for these mechanisms in action.
Is it true that the basic mechanisms of evolutionary change cannot be observed in nature?
No. Natural selection can work very quickly and the observed morphological and behavioral changes are well documented. The observations on both drift and gene flow can be determined in populations small enough in a very short time. Go here for greater detail. talkorigins.org

What are other evolutionary mechanisms besides natural selection?
Other evolutionary mechanisms besides natural selection include genetic drift, gene flow, mutation, and sexual selection. Genetic drift is the random change in allele frequencies in a population. Gene flow refers to the transfer of genes between populations. Mutation introduces new genetic variation, and sexual selection drives evolutionary change through mate choice and competition for mates.
A subjective change or complaint that cannot be easily observed or measured is called a?
Subjective change or complaint that cannot be easily observed or measured is called a symptom. Symptoms are experienced or reported by the individual without external verification.
Current details about the evolutionary process?
Scientists currently think that the evolutionary process is ongoing. Species that cannot adapt do not survive; those that can change and evolve are more successful.
How does observed evolutionary change support the scientific theory of evolution?
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
What are some common phylogenetic tree questions that researchers often explore in the field of evolutionary biology?
Researchers in evolutionary biology often explore questions related to the relationships between different species, the timing of evolutionary events, the patterns of genetic variation within and between species, and the processes driving evolutionary change. They may investigate the evolutionary history of specific groups of organisms, the impact of environmental factors on evolution, and the mechanisms underlying the diversification of life on Earth.
What is Phyletic change?
Evolutionary change is a process where things change over a period of time. Such as going from a candle, to a light bulb.
What can lead scientist to change an evolutionary tree?
What can lead scientists to change an evolutionary tree?
What is the name for this type of rapid evolutionary change?
The name for this type of rapid evolutionary change is "punctuated equilibrium."
Define evolutionary theory?
Evolutionary theory is a scientific explanation for the mechanisms and patterns of biological evolution, proposing that species change over time through the process of natural selection, genetic drift, and other factors. It helps to understand how organisms have evolved and diversified over generations.
