Does evolution often proceed at different rates for different organisms?

Yes. There is no set rate for evolution; the speed by which populations diverge behaviourally, morphologically and genetically is determined entirely by circumstance. Even different genes in the same population gene pool can have different rates of evolution.

How would a scientist explain how organisms often seen perfectly suited to their environment?
Evolution.
Pros and cons of atheistic evolution?
Atheism and Evolution are two different things that are often miscombined. Atheism is a belief or philosophy that there are no Deities. Evolution is a biological process whereby the structure and genetic code of organisms change over many generations, as particularly unsuccessful organisms die without offspring and particularly successful organisms are likely to have more offspring. The characteristics of the successful organism thus become the norm.There is no particular reason to link them, other than the fact that atheists are less likely to reject evolution on the basis of their philosophy.
How has biochemical taxonomy changed the theory of evolution?
Biochemical taxonomy has not changed the theory of evolution. It is another way of studying the relationships between organisms and figuring out how the tree of life has branched. It can often provide clues when external appearances are confusing.
Gradual change in populations of organisms that occurs when the environment changes?
This is known as evolution. Evolution is the gradual change in the heritable characteristics of biological populations over successive generations due to factors such as natural selection, genetic drift, and mutations. It occurs in response to changes in the environment and can result in the adaptation of organisms to better survive and reproduce in their environment.
What statement is best supported by the theory of evolution?
Simple statement I often use to illustrate the definition of the theory of evolution by natural selection proceeded by the definition of evolution itself. Evolution is the change in allele frequency over time in a population of organisms. Natural selection is the nonrandom survival and reproductive success of randomly varying replicating organisms.
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 does a symboitic mean?
do you mean Symbiotic - it is when two organisms, of different species, live together, often for their mutual benefit
Why is evolution difficult to demonstrate in a laboratory?
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.
Who propounded the idea of gradualism in evolution?
Charles Darwin and he was rather insistent about the process of evolution being gradual and incremental. He and Thomas Huxley argued about this point often. Today we know that evolution has different speeds depending on organism and environment, but there is no " hopeful monster " jump in evolutionary processes.
How and why does natural selection drive the evolution of eukaryotes?
It is often believed that species evolve to become better and become an ultimate organism.This is a misconception. Evolution becomes parallel and takes place simultaneously in different species. Evolution may also be continuous mutation. Evolution takes place simply to ensure better survival in the current habitat.
How do vestigial structures provide evidence that we evolved from organisms that existed in the past?
Vestigial structures are anatomical features that have lost their original function in an organism but are still present. These structures often have similarities to functional structures in related organisms, suggesting a shared evolutionary history. By studying these vestigial structures, scientists can infer how organisms have changed over time through the process of evolution.
What is often a result of evolution?
Adaptation, divergence and speciation.
