Step by step
Solved in 3 steps
- You have the chance to use the very first time-machine created by humans. You volunteer to travel 520 million years back in time to collect coastal marine animals. The first organism you encounter is unusual looking and does not resemble any extant organism you know. You notice that the body is segmented, and the segments are not identical. You also notice that the organism has well developed eyes and one pair of long antennae. Their jointed appendages are branched but unequal in size and have various shapes. Moreover, the body appears to be rigid and covered dorsally with numerous spines. Try to classify this organism (e.g., its phylum) based on its appearance and describe its symmetry. Then speculate on its ecology, likely life history (reproduction), and key developmental features. The second organism that you encounter is fixed to the substrate, firm, and has fan shape with finger like projections. It is brightly colored. As you observe it, a few branches of the fan break off. You…Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects? All these organisms require oxygen to survive. The earliest fish fossils are found in the lowest strata of sedimentary rocks, followed by insects, and then humans. The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans. Fossils of ancient fish and human ancestors have been discovered in the same sedimentary rock layers.Over the long period of time that life has existed on Earth, there have been a number of important or significant innovations including (but not limited to) endosymbiosis to create mitochondria and chloroplasts; multicellularity; adaptation to land by plants and animals; development of exoskeletons in arthropods, shells in molluscs, and notochords followed by vertebral columns in chordates and vertebrates; and bipedalism in the ancestry of humans. All of these had to come about by natural selection in response to changing environmental forces. After studying the textbook reading assignment, pick one of the significant innovations listed above and describe:: a. How the innovation appears to have happened b. What environmental challenges were met and overcome by this innovation, and c. What opportunities were opened for the organism that made this innovation B. You must include in your post an example of at least one species and demonstrate that vou understand scientific nomenclature by…
- How can embryos help scientists understand evolution? Embryos go through various stages that suggest the animal’s evolutionary process. Embryos are frequently fossilized and illustrate change over time. Embryos provide evidence for which life forms existed at the same time. Embryos contain the code for all life on Earth.What is Evolution of living things ?human frog bat porpoise horse These vertebrates have the same basic arrangement of bones. Which row below identifies the term used, in an evolutionary sense, to describe the arrangement of bones and provides a correct definition for this term? The statement above is best completed by the answers in row: Row Term Definition analogous structures body parts that perform similar functions even though the organisms do not have a common evolutionary origin body parts that perform similar functions even though the organisms do not have a common evolutionary origin homologous structures homologous structures structures that have similar structural elements and origin but may have a different function analogous structures structures that have similar structural elements and origin but may have a different function
- As we progress through evolutionary time in the animal kingdom, certain trends emerge. Which is NOT a general trend observable in animal evolution? A general trend towards having a true body cavity A general trend towards asexual reproduction A general trend towards increasing tissue and organ development A general trend towards increasing cephalizationWhat are the largest animals ever to have lived on Earth? From what animals are they thought to have evolved?For this activity, you should familiarize the diverse group of vertebrates and make a phylogenetic tree showing their evolutionary relationships. This tree should be primarily based on physical characteristics, such as: I. Presence or absence of a backbone II. Ability to breathe in air or water III. Cold or warm blooded IV. Carnivore, herbivore, or omnivore V. Presence or absence of hair/fur VI. Any other external structure such as horns TO DO: Lay all the animals on their desks and separate them into two groups using the physical characteristics above☝ The animals are on the picture.
- In the late 1800s, a biologist studying animal embryos coined the phrase “ontogeny recapitulates phylogeny,” meaning that the physical development of an animal embryo (ontogeny) seemed to retrace the changing form of the species during its evolutionary history (phylogeny). Why would embryonic development retrace evolutionary steps?Using vertebrates as an example, how does comparative embryology prove evolution?Which of the following is not a statement of von Baer's laws? Less general characters develop from the more general, until finally the most specialized appear. The general features of a large group of animals appear earlier in development than do the specialized features of a smaller group. (C) All of the above are Statements of von Baer's laws. The early embryo of a higher animal is never like a lower animal, but only like its early embryo. The embryo of a given species, instead of passing through the adult stages of lower animals, departs more and more from them.
