Developmental Biology - Embryology
Many scientists use what an organism looks like as an
embryo, or embryology, as evidence for evolution. The
embryos of most vertebrates look very similar and have similar structures. For example, fish, bird, rabbit, and human embryos are similar in appearance in early stages. They all have gill slits and a tail with muscles to move it. Later as the embryos develop, they become less and less similar.
What does the study of embryology show when comparing most vertebrates?
Evolution is the theory that species change over time. According to this theory, new species form from existing species through variation and natural selection. The evolutionary process is very slow and the transformation of one species into another requires thousands of years. Several evidences are used to prove evolution and somehow reconstruct how this process occur:
1.Fossil Records.
2.Homologous Body Structures.
3.Vestigial structures.
4.Similarity of embryo.
5.Geographical evidence
Which statement is true?
Fossils can provide information about when life forms existed.
Fossils cannot provide information about life cycles and behaviors.
Fossils cannot provide information about relatedness of life forms.
Fossils can provide information about the entire evolutionary process of life forms.

- The Theory of Evolution contends that species have changed through time and are related to one another through descent from a common ancestor. Which of the following prediction follow from the Theory of Evolution? A. The fossil record should contain intermediate forms between major taxonomic groups B. The oldest rock strata are much more likely to contain complex fossils than simple fossils. C. Fossils are always a representation of species that are currently alive (ie extant) even if they have not been detected yet as living on earth at the present time D. All species are unigue and originated independently from each otherarrow_forwardTransitional species are species important in helping scientists determine the evolutionary path that species have taken over long periods of time. Lobe-finned fishes are the ancestors of amphibians and have fossils that are found in rocks that are at least 380 million years old. Fossils of the oldest amphibian-like vertebrate animals with true legs and lungs are found in rocks that are approximately 363 million years old. Paleontologists have found a sample of rock that is approximately 370 million years old which contains what seems to be a link between lobe-finned fishes and amphibians. Which of the following is a characteristic that you would not expect to see in this transitional fossil? Question options: Skeletal structures that indicate the development of legs. An intermediate structure between lungs and gills. Teeth that are intermediate to the lobe-finned fishes and amphibians. A neck that is more flexible than lobe-finned fishes.arrow_forwardWhat type of evolution does a bird have? Divergent, Convergent, or Parallel?arrow_forward
- 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?arrow_forwardEvolution in Humans: 1) describe several techniques that paleontologists today use to establish fossil age 2) describe how tracking changes in DNA sequence among related organisms can be used to create a migration maparrow_forwardIn a phylogenetic analysis of several bird species, a researcher uses a species of reptile as an outgroup. Which of the following is the main reason for including an outgroup in the analysis? To identify ancestral traits shared by the bird species To determine the overall genetic diversity of the bird species To establish a new monophyletic group including both bird and reptile species To analyze the convergent evolution of bird and reptile speciesarrow_forward
- A biologist is trying to infer how five closely related species of snakes are related to one another. She notices that some of the snakes have forked tongues and others do not. Which of the following would help her distinguish the ancestral state? Group of answer choices She looks at a representative mammal species to see if it has a forked tongue. She locates a specimen of a more closely related snake to see if it has forked tongue. She looks among snakes fossils for evidence that being forked is a characteristic of the ancestor of this group, but determines no such fossil exist. She flips a coin.arrow_forwardA researcher studying the wing structures of bats, birds, and insects finds that while they all have wings, their underlying bone structures and development are different.

- 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.arrow_forwardFossils show that dinosaurs originated between 200 and 250 million years ago. Would you expect the geographic distribution of early dinosaur fossils to be on multiple continents or on a single continent? Explain. Hint: refer to continental drift in your explanation.arrow_forwardA number of scientists believe that the Permian extinction was caused by huge volcanic lava flows (from the Siberian traps) that may have caused low oxygen concentrations compared to the high oxygen levels in the Permian. Does this low oxygen level after the Permian extinction make it likely that dinosaurs, especially large ones, did not evolve immediately after the Permian extinction (252 million years ago)? Why or why not?arrow_forward
