Which of the following best describes why the process of evolution is easier to study in fruit flies than in birds?
Because fruit flies have small cell counts Because the life cycle of a fruit fly is short enough to actually see a change in a short period of time. With larger animals, it could take many years to see an actual change. With fruit flies, you can see many generations of change in a shorter period of time.

Why do we have a good evolutionary record of the horse?
Horses have a good evolutionary record because they have a well-preserved fossil record due to their large size and distinctive anatomy, making them easier to study. Additionally, horses have been extensively studied and researched by paleontologists and scientists, leading to a wealth of information on their evolutionary history. Finally, the evolution of the horse is considered a classic example of evolutionary theory, which has spurred further interest and research in this area.
Concept of evolution?
Evolution can be a confusing term because it is used in more than one way. Many people in the general population have developed an incorrect understanding of evolution for a number of reasons. One is the misinformation spread by creationists - by misrepresenting evolution, they may hope that it will be easier to get people to disregard it. Another is simple ignorance of the topic itself and the specific ways in which science uses certain terminology.Because evolution is so complex, however, it is important to get a handle on the different ways in which the term can be used. There are, of course, broader uses - we can talk about the evolution of the universe or the evolution of the planet Earth. In such cases, evolution simply refers to change over time, but that isn't what concerns us here.Biology, in contrast, uses the term evolution a bit more specifically. At its most basic, evolution in biology can be used to refer either to the change in the gene pool of a population over time or to the concept of descent with modification. Here are some examples from basic biology texts:"In fact, evolution can be precisely defined as any change in the frequency of alleles within a gene pool from one generation to the next." Helena Curtis and N. Sue Barnes, Biology, 5th ed. 1989."Biological evolution ...is change in the properties of populations of organisms that transcend the lifetime of a single individual." Douglas J. Futuyma in Evolutionary Biology, 1986.The two definitions look a bit different, but they are expressing similar things - the first is to a large extent more technical. An allele is a particular form of a gene and if a single gene is responsible for eye color, then one allele is for brown eyes, another allele is for blue eyes, and so on.So, if the frequency of the allele for blue eyes changes in a population over time, that means that evolution has taken place. This may not seem like a very significant step in evolution, but the fact of the matter is most evolutionary steps are quite small - large changes are the result of many, many smaller steps.The second common use of the term evolution within biology is for the concept of common descent, the idea that all living beings are descended from a common ancestor. This typically occurs in the context of allele frequencies changing in populations over time, but there are also other factors as well. Thus, "change in allele frequency over time" is a narrow and technical definition of evolution while "descent with modification" is a broader understanding.Lance F. contributed information for this.
Why do dogs respond better to using two syllable?
Although dogs have excellent hearing, their hearing and cognition are not as well attuned to the subtle differences in human words as are our ears. Commands and instructions that have two syllables are not required, but they can make it easier for a dog to understand some things.
What does genetic technology make it easier to give cows growth hormones?
Genetic technology makes it easier to give cows growth hormones. This is because it is now easier to transfer the hormones.
Why are teeth like a wedge?
Teeth function like wedges because their shapes allow them to effectively break and split food apart. The pointed edges of teeth concentrate force on a small area, making it easier to penetrate and shear through tougher materials. This wedge-like action facilitates chewing, helping to mechanically digest food for easier swallowing and digestion. Thus, their design enhances efficiency in the eating process.
