- For more than two billion years after that, life was housed in the bodies of many kinds of tiny, single-celled organisms, some of which produced the oxygen that now makes up more than a fifth of the earth's atmosphere.

- Astronomers used these measurements to demonstrate that the age-old human explanations of the heavens were incomplete. In the process, they replaced a complex and confusing explanation with a simple one: the sun, rather than the earth, is at the center of a "solar system," and the earth revolves around it. That simple step—a bold departure from past thinking due mainly to the insights of Copernicus to —dramatically changed the picture of the then known universe. This concept of heliocentricism initially ran counter to the positions of religious authorities.Link: http://kanpuruniversity.org/syllabus/ba_economics.pdf
- Galileo was told to abandon his beliefs, and he later was tried by the Inquisition and sentenced to the equivalent of house arrest. The Church held that his views were dangerous to faith. Continued study and ever more careful measurements of the movements of the planets and sun continued to support the heliocentric hypothesis. Then, in the latter half of the 17th century, Isaac Newton to showed that the force of gravity—as measured on the earth—could account for the movements of the planets given the laws of motion that Newton derived.Link: https://ktet.kerala.gov.in/syllabus/syllabus3.pdf
- As a result of the steady accumulation of evidence, the theological interpretation of celestial movements gave way to the naturalistic explanation, and it is now accepted that night and day are the consequences of the rotation of the earth on its axis. Today, we can see for ourselves the rotation of the earth from satellites orbiting the planet. Like biological evolution, the theory of heliocentricism brought order and new understanding to an otherwise chaotic and confusing aspect of nature.Link: https://chcece004answer.blogspot.com/
- It also had great practical applications, in that the exploration of the world by European seafarers used the more accurate understanding of celestial mechanics to assist in navigation. But that experience is now informed not only by the beauty and majesty of the heavens, but by a deeper understanding of nature and by an appreciation of the power of the human intellect. This triumph of the human mind says a great deal about the nature of science. First, science is not the same as common sense. Common sense indicates that the sun does rise and set. Nevertheless, there can be other explanations of that phenomenon, and one of them, the rotation of the earth on its axis, is responsible for day and night.Link: https://psytech.com/Content/SampleReports/EN/P-15FQP-Comp-Development.pdf
- A concept based on observation proved to need extensive modification as new observations accumulated. Second, the statements of science should never be accepted as "final truth. Nevertheless, in the case of heliocentricism as in evolution, the data are so convincing that the accuracy of the theory is no longer questioned in science. Third, scientific progress depends on individuals, but the contributions of one individual could be made by others. If Copernicus had kept his ideas to himself, the discovery of heliocentricism would have been postponed, but it would not have been blocked, since other astronomers eventually would have come to the same conclusion.Link: https://docs.bromcom.com/knowledge-base/how-to-add-non-edi-exam-results/
- Biologists have used construction cranes to study the many newly discovered species that live in the canopies of tropical forests, as in this research project in Panama. Similarly, had Darwin and Wallace not published their hypotheses, the concept of biological evolution would nevertheless have emerged as the accepted explanation for the history of life on earth. The same cannot be said in other areas of human endeavor; for example, had Shakespeare never published, we would most assuredly never have had his plays. The publications of scientists, unlike those of playwrights, are a means to an end—they are not the end itself. Science Requires Careful Description What are the scientific methods that have led to our current understanding of the history of life over vast eons of time?Link: https://questions.examside.com/past-years/gate/question/poor-collapsibility-of-the-mold-leads-to-type-of-casting-def-gate-pi-1989-marks-1-k697telnaf6ohkqk.htm
- They begin with careful descriptions of the material being studied. The material for the study of biological evolution is life itself. One basic aspect of life is that individuals can be grouped as similar kinds, or species. Another important observation is that many species seem to be closely related to each other. The scientific classification of species and their arrangement into groups began with the publication in of Systema Naturae, or system of nature, by the Swedish naturalist Carolus Linnaeus to For example, Linnaeus knew seven dog-like species, and he gave each a double name.Link: https://youtube.com/watch?v=bUJW6gTz7Bo
- Subsequently many more species were discovered and some of the names were changed—and continue to be changed as more information is obtained. The domestic dog is Canis familiaris; the coyote of North America is Canis latrans ; the Australian dingo is Canis dingo; and the wolf of the northern hemisphere is Canis lupus.Link: http://admin.warmiehealth.com/the_halflings_gem_forgotten_realms_icewind_dale_3_legend_of_drizzt_6_ra_salvatore.pdf
- Thus Canis is the name of the genus of dog-like animals, and the distinctive second name is the species name. Whereas Linnaeus recognized about 9, species, systematists now have recognized about 1. The task of categorizing and describing species is still far from complete. Most species of smaller invertebrates, and many bacteria and other microscopic organisms, remain to be discovered. The plant kingdom is also incompletely known. Though the flowering plants of many areas, such as Europe and North America, are fairly well described, many other regions have not been nearly as well explored by botanists.Link: https://iaspaper.net/iiser-2021/
- Recent investigations in the exceptionally diverse rainforests of South America have caused biologists to raise their estimates of the number of undescribed species. For example, a very high proportion of insects collected from the forest canopy are "new" species to science. It is now believed that the number of different species of plants and animals in the world may be ten million, or even more. The scientific methods used in classifying organisms have been greatly improved over time. The process begins with the intensive field work in which the animals, plants, and microorganisms are collected and carefully examined. Most will be known to a specialist, but there might be some unusual examples. However, none is likely to be a complete stranger, since the specialist will probably recognize that any puzzling specimen is similar to some familiar species.Link: https://sway.office.com/oYp2kYIJrR2tFEJD
- Next the specialist must check all that has been published on the group of organisms that contains the similar species. If, after an exhaustive search, there is no record of a described species that corresponds to the one being examined, the specimen is probably a new species. The specialist will then prepare a careful description of the new species and publish it in a scientific journal. There is a permanent reward for being the describer of a new species: thereafter monographs that deal with the classification of the group to which the new species belongs will add the describer's name at the end of the scientific Despite their similarities with birds, bats are mammals that evolved from flightless ancestors. Thus, for example, "Homo sapiens Linnaeus" is our own proper identification, because Linnaeus was the first to give us our scientific name. This example makes it clear that not all scientific data are derived as the result of experimentation. The conventional classification of species into seemingly natural groups involved the careful observation of a variety of different species, followed by the use of selected characteristics in an attempt to define groups of species thought to be related.Link: https://academia.edu/9532225/Turkeys_EEZ_in_the_Mediterranean_Sea_The_Case_of_Kastellorizo
- But the groupings are not always obvious. For example, it might have seemed reasonable to classify bats with birds, since the most conspicuous characteristic of each is the ability to fly. But bats are mammals. Like all mammals, their bodies are covered with hair and their young are born alive instead of hatching from eggs and are nourished by milk from the mother's mammary glands.Link: https://ctan.org/topic/exam
- Although most of the species we know today were described after the time of Linnaeus, we continue to use his basic system of hierarchical classification. For example, similar genera are united in families, similar families in orders, similar orders in classes, and similar classes in phyla. The dog-like species listed above the genus Canis , plus a number of similar but more distant dog-like animals, are grouped as the family Canidae. This family plus the families of cats, bears, seals, and weasels form the order Carnivora.Link: https://jobskar.com/jobs/icfre-recruitment-jan-2021-apply-online-for-01-chair-of-exellence-post
