Which of the following statements about evolution is true
Which of the following statements is correct?
A scientist finds two populations of the same insect species with the same members. Members of one population can be found deep in the woods in the leaf litter. Members of the other population can be found in the woods’ edge grass. The biologist decides that the members of the two groups should be classified as two distinct species. What species definition does this biologist use the most?
Consider the situation below and choose the best answer. Since African firecracker seed finches eat either large or small seeds, they have either large or small beaks. Which of the above is most likely the cause of this?
Consider the situation below and choose the best answer. The sickle allele (HbS) is very common in malaria-prone areas of Africa. Which of the following statements better describes the situation?
When species with one extreme of a trait distribution (such as height, weight, etc.) have a greater chance of survival than those with the opposite extreme of the same trait, what form of selection is likely at work?
Which of the following statements are true?
Teachers are often confronted with challenging questions about evolution, many of which come from parents and others who disagree with evolution being taught. These questions have good scientific answers, which build on the evidence for evolution as well as the nature of science. This chapter contains brief responses to some of the most frequently asked questions.
In the broadest context, evolution explains why what we see now differs from what occurred previously. Galaxies, stars, the solar system, and the earth have all evolved over time, as has life on the planet.
Biological evolution is the study of shifts in living beings over the course of the earth’s history. It describes how all living things have ancestors in common. Evolutionary transition produces new species over time. This method was dubbed “descent with alteration” by Darwin, and it is still a good definition of biological evolution today.
The beliefs behind “creation science” are based on the belief that God created the universe—including humans and other living things—all at once in the recent past. However, scientists from a variety of fields have looked into these claims and found them to be scientifically unsound. Many different methods of determining the age of rocks, for example, are incompatible with evidence for a very young planet. Furthermore, since creation science’s fundamental propositions are not checked and confirmed, they do not meet the standards for science. Indeed, US courts have found that creation science theories are religious convictions that cannot be taught alongside evolution.
Which of the following statements about lamarck is true
Many scientists and philosophers of science have referred to evolution as both fact and theory, a term coined by paleontologist Stephen Jay Gould in an article published in 1981. In science, he defines fact as data that isn’t known with utter certainty but is “proven to such a degree that withholding provisional assent would be perverse.” 1st A well-supported scientific theory is a well-founded interpretation of certain evidence. Observational confirmation of modern processes, defects in species recording historical common descent, and transitions in the fossil record all add to evolution’s facts. Evolutionary theories give a partial explanation for these evidence.  The terms evolution, reality, and theory all have different definitions depending on the context. As in stellar evolution, evolution refers to transition over time. [requires citation] In biology, it refers to observed changes in species, their descent from a common ancestor, and at a technical level, a shift in gene frequency over time; it may also refer to explanatory theories that describe the processes of evolution (such as Charles Darwin’s theory of natural selection). To a scientist, reality can refer to a repeatable observation that everyone can agree on, something that is so well known that no one in the group can argue with it, or the validity or falsity of a proposition. To the general public, theory may refer to an opinion or conjecture (e.g., “it’s just a theory”), but it has a much stronger connotation among scientists, referring to a “well-substantiated explanation.” People may also speak over each other with too many options, and definitions become the subject of linguistic study.
Which of the following statements is not correct ?
Inheritable traits that enhance their survival and reproductive success in the local environment- Non-inheritable traits that enhance their survival and reproductive success in the local environment- Non-inheritable traits that enhance their survival and reproductive success in the local environment- Non-inheritable traits that enhance their survival and reproductive success in the local environment- Non-inheritable traits that enhance their survival and reproductive success in the local environment- Non-inheritable traits that enhance their survival and reproductive success in the local environment-
Both of the following are elements of Charles Darwin’s natural selection theory. EXCEPT-Most members of a genus do not live long enough to reproduce. – Genes on chromosomes pass down characteristics of species. Members of a species that are well adapted will live and reproduce more effectively.
Which of these people is the most likely to succeed in terms of evolution?
– A 100-year-old organism that produces two offspring, both of which live to reproduce.
– A male who mates with 20 females and has one child- An organism that dies after 5 days but leaves 10 offspring, all of whom live to reproduce
