Question 11. SURVEY. 300 seconds. Q. A group of mice was released into a large field to which no other mice had access. Immediately after the release, a representative sample of the mice was captured, and the fur color of each individual in the sample was observed and recorded. There were 10% gray mice, 80% brown mice and 10% black mice Analogous structures don't have to share the same evolutionary path. One analogous structure might have come into existence long ago, while the analogous match on another species may be relatively new. They may go through different developmental and functional stages before they are fully alike Question 13. SURVEY. 30 seconds. Q. Which best explains why the wing of a bat and the fin of a whale are similar? answer choices. a mutation in nature that caused them to be similar. a common ancestor between the bat and the whale. a simple coincidence between the bat and the whale Dolphins and sharks are other notable examples of analogous structures and convergent evolution. The two animals share many features, including their overall body shape, coloration and fin placement. Yet dolphins are mammals while sharks are fish, meaning that in terms of evolutionary lineage dolphins share more in common with rats than sharks Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose. The term analogous structures comes from the root word analogy, which is a device in the English language where two different things on a basis of their similarities

Chapter 21 Flashcards Quizle

Analogous structures are easily identifiable when wings of different organisms are studied. For example, the wings of a bird and insect perform the same function, i.e., flying or movement through the air. But, insects have evolved separately, whereas birds are the modern versions of the ancient dinosaurs; both the classes are not related in any. Homologous and Analogous Structures Are Derived from Molecular Changes. To conclude, anatomical structures in animals or plants frequently diverge in function due to DNA mutations or epigenetic regulation, resulting in homologous structures in future offspring if the change is favorable for the survival of that organism Analogous Structures: Analogous structures cannot be used to infer evolutionary relationships among species. Conclusion. Homologous and analogous structures are two types of structures found in species as an adaption to the environment. Homologous structures are derived as a result of divergent evolution The structures in this case are known as analogous structures. Examples of analogous structures range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins.

Which of the following best represents analogous

  1. 14. Which of the following statements best explains why geographic isolation can lead to speciation? Physical separation of populations reduces competition for each group. Physical separation of populations prevents interbreeding and mixing of gene pools. Physical separation of populations provides more space for each group's size to increas

CONTENTS. 1. Overview and Key Difference 2. What are Homologous Structures 3
  3. Analogous / Convergent Structures . Some biological characteristics are analogous (also called convergent), which means that they serve the same function in different species but they evolved independently rather than from the same embryological material or from the same structures in a common ancestor. An example of an analogous structure would be the wings on butterflies, bats, and birds

Explain analogous organs and homologous organs. Identify the analogous and homologous organs amongst the following: Wings of an insect, wings of a bat, forelimbs of frog, forelimbs of a human. Answer: Analogous organs are those organs which have different structural designs and origin but perform similar functions compared, certain features can be described as either analogous or homologous. For example, flight requires certain rigid aeronautical principles of design, yet birds, bats, and insects have all (line 5) conquered the air. The wings of all three types of animals derive from different embryological structures, but they perform the same functions common ancestor. These structures may serve many different purposes, but they are still made up of similar parts. b. Analogous structures = such as the wings of bats and birds, have the same function, but examining the structures show that the organisms did not come from a recent common ancestor. 4. Embryology = the study of embryos 17.Which statement would most likely have used by Lamarck to explain the development of the long trunk in elephants? 1)all these animals can swim 2)pigs developed from chickens 3)these animals may have had a common ancestor 4)gill slits and tails are required for embryonic development 18.The embryos of fish, chickens, and pigs have gill slits.

Vestigial Structures. Structures like the human tail bone and whale pelvis are called vestigial structures. Evolution has reduced their size because the structures are no longer used. The human appendix is another example of a vestigial structure. It is a tiny remnant of a once-larger organ. In a distant ancestor, it was needed to digest food Answers is the place to go to get the answers you need and to ask the questions you wan In biology, homology is similarity due to shared ancestry between a pair of structures or genes in different taxa.A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod. Comparative anatomy, the comparative study of the body structures of different species of animals in order to understand the adaptive changes they have undergone in the course of evolution from common ancestors. skeletons of humans and gorillas compared. The skeletal structure of a human being (left) and of a gorilla (right) Analogous Structures. The opposite of homologous structures are analogous structures, which are physically similar structures between two taxa that evolved separately (rather than being present in the last common ancestor). Bat wings and bird wings evolved independently and are considered analogous structures

Examples of Organisms . The more closely organisms are related, the more similar the homologous structures are. Many mammals, for example, have similar limb structures.The flipper of a whale, the wing of a bat, and the leg of a cat are all very similar to the human arm, with a large upper arm bone (the humerus in humans) and a lower part made of two bones, a larger bone on one side (the. The evidence for evolution. In this article, we'll examine the evidence for evolution on both macro and micro scales. First, we'll look at several types of evidence (including physical and molecular features, geographical information, and fossils) that provide evidence for, and can allow us to reconstruct, macroevolutionary events Analogy . Analogy, or analogous structures, is actually the one that does not indicate there is a recent common ancestor between two organisms. Even though the anatomical structures being studied look similar and maybe even perform the same functions, they are actually a product of convergent evolution.Just because they look and act alike does not mean they are related closely on the tree of life

An analogy is a comparison between two objects, or systems of objects, that highlights respects in which they are thought to be similar.Analogical reasoning is any type of thinking that relies upon an analogy. An analogical argument is an explicit representation of a form of analogical reasoning that cites accepted similarities between two systems to support the conclusion that some further. Academia.edu is a platform for academics to share research papers 3 Examples of Convergent Evolution. To observe convergent evolution in nature, evolutionary biologists seek out different organisms that show independent evolution of similar features, similar structures, or similar traits. Marine animals: Fish and dolphins are vastly different animals with different underlying DNA sequences and nervous systems

These are called analogous structures (). Similar traits can be either homologous or analogous. Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous, but not homologous Which one of the following statements is correct? (a) Australopithecus is the real ancestor of modern man (b) Neanderthal man is the direct ancestor of Homo sapiens (c) Homo erectus is the ancestor of man (d) Cro-magnon man's fossil has been found in Ethiopia. Answer and Explanation: 40 Define homologous and analogous organs. (2011 D) Classify the following as homologous or analogous organs: (i) Wings of an insect and wings of bat. (ii) Forelimbs of a man and forelimbs of a frog. Answer: Homologous organs: Those organs which have the same basic structure or same basic design but different functions, are called homologous organs In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar.

Spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. Spores thus differ from gametes, which are reproductive cells that must fuse in pairs in order to give rise to a new individual.Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction.Spores are produced by bacteria, fungi, algae, and plants Many mammals have tails, which are one of the best examples of homologous structures. The tails of rats, cats, monkeys and many other mammals are extensions of the torso, being made out of vertebrae capable of flexing. Tails are used for balance in many animals, and to ward off insects. While humans don't have tails, we do have a tailbone

  4. Convergent evolution — the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait — is rife in nature, as illustrated by the examples below. The ultimate cause of convergence is usually a similar evolutionary biome, as similar environments will select for similar traits in any species occupying the same ecological niche, even if those species are.
  5. Analogous organs have a similar function. For example, the bones in a whale's front flipper are homologous to the bones in the human arm. These structures are not analogous. A butterfly or bird's wings are analogous but not homologous. Some structures are both analogous and homologous: bird and bat wings are both homologous and analogous

Following are some examples of homology: The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar and share common traits

Misconceptions about evolutionary theory and processes. MISCONCEPTION: Evolution is a theory about the origin of life. CORRECTION: Evolutionary theory does encompass ideas and evidence regarding life's origins (e.g., whether or not it happened near a deep-sea vent, which organic molecules came first, etc.), but this is not the central focus of evolutionary theory Comparative anatomy is the study of similarities and differences in the anatomy of different species.It is closely related to evolutionary biology and phylogeny (the evolution of species).. The science began in the classical era, continuing in Early Modern times with work by Pierre Belon who noted the similarities of the skeletons of birds and humans.. The other type of change is called antigenic shift.. Antigenic shift is an abrupt, major change in an influenza A virus, resulting in new HA and/or new HA and NA proteins in influenza viruses that infect humans. Shift can result in a new influenza A subtype in humans. One way shift can happen is when an influenza virus from an animal. Purkinje, in fact, deserves much of the credit that usually goes to Schwann, for in 1837 he proposed not only that animals were composed principally of cells and cell products (though he left room for fibers) but also that the basic cellular tissue is again clearly analogous to that of plants (Harris 1999, p. 92) Evidence of common descent of living organisms has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating that all life on Earth comes from a single ancestor.This forms an important part of the evidence on which evolutionary theory rests, demonstrates that evolution does occur, and illustrates the processes that created Earth's biodiversity

Examples of analogous structures range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins and fish. Plants and other organisms can also demonstrate analogous structures, such as sweet potatoes and potatoes, which have the same function of food storage Analogous structure emerges from convergent evolution. Homologous Structures. Homologous structures are similar in two organisms which have the same ancestors but the functions performed may or may not be the same. For instance whales, birds and humans all possess the same arm bone structure. Another example of the homologous structure is.
