- Life on earth has lasted an estimated 3.5 billion years, experiencing different environmental change like extreme heat and ice age. But living organisms on Earth have their seasons, and all living things will be wiped out eventually. Having learned about the different type of evidence used to proved evolution, hypothesize how human beings will adapt in the next five years. Direction: List down five adaptation that our species may develop in order to continue surviving on Earth. Explain each adapation.1)Provide a scientific example of evolution and/or natural selection. You can use human and/or animal examples.2) Describe how the animal/species developed an advantage over time or what the evolutionary process was.3) Give a source for where you located your information.Explain why the following statement is incorrect. “Evolution gives species what they need in order to survive”
- It has taken millions of years for the ancestors of whales to change into what we know today, as indicated in the diagram below. Based on your knowledge of evolution, which of the following is a reasonable explanation of why the organisms in the diagram changed over 25 million years? Question options: As the environment changed the food sources became more difficult to obtain so characteristics that allowed the organisms to hunt in an aquatic environment became more advantageous. As the environment changed the temperature became too hot and the organisms began to move to a more aquatic environment to keep cool. As the environment changed the food sources became more difficult to obtain so the organisms decided to change their characteristics to ones that would be beneficial when hunting in an aquatic environment. As the environment changed the predators on land became better adapted to hunting the whales ancestors forcing them to live in more aquatic…Select the true statements from the following regarding the evolutionary theories that are thought to have combined to give rise to life on earth. Reproduction is required for both chemical and biological evolution. Both chemical and biological evolution are defined by change over time. Purpose of Miller-Urey experiment was to answer the question: can chemistry give rise to complex molecules required for life? The Miller-Urey experiment showed that chemistry can give rise to the molecules required for evolution of life.In the early nineteenth century, the French scientist Georges Cuvier provided conclusive evidence of the extinction of species on Earth. Although Cuvier correctly asserted that a series of catastrophes led to these extinctions, he could not provide a testable explanation of the source of the new animals and plants that appeared after the extinction of older forms. How would you argue that modern evolutionary theory provides an explanation for the proliferation of new forms of life after mass extinctions?
- Write short paragraphs explaining each of the following statements:(a) Natural selection chooses from among the individuals in a populationthose most suited to current environmental conditions. It does not guarantee survival under future conditions.(b) Individuals do not evolve, but populations do.(c) The organisms that exist today do so because their ancestors had traits that allowed them and their offspring to thrive.(d) At the molecular level, evolution can take place by the replacement of one nucleotide by another.(e) Evolution is said to have occurred within a population when measurable genetic changes are detected.The diversity of life is explained by the theory of evolution. Living things on Earth evolve by (1); that is, the selective survival of individuals of a species possessing a trait that increases their (2). Natural selection relies on the natural variations in a population of a species caused by (3).Define evolution: What is decent with modification? Use Mosquitoes and DDT to explain natural selection. What does the term fitness mean in the context of evolution?
- Describe the modern theory of evolution and discuss how it is supported by evidence from two of the following three areas;population genetics, molecular biology and comparative anatomy and embryology. Evolution is one of the major unifying concepts of modern biology. Explain the mechanism that leads to evolutionary change. Describe how scientists use each of the following as evidence for evolution ;bacterial resistance to antibiotics, comparative biochemistry and fossil records.Scientists classify living things in order to organize the astonishing diversity of life on Earth. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA. Molecular similarities show that organisms are related. In other words, they are descendants of a common ancestor in the past. As we said earlier in our discussion, there are species that needs to be named and some are to be discovered. However, with the current environmental situation we have at the present (pollution, exploitation of resources, forest fires, and others), these species that are yet to be identified are being endangered and at the verge of extinction. As a matter of fact, the University of Turku reported last July 1, 2020 that there are 15 million estimated different species living in our planet but 2 million of them are currently known to science. Discovering these remaining species is important for them to be protected. Also,…In 100 words, explain in detail the two things that govern the rate of evolution.
