All of the following pieces of evidence can be used to determine relatedness among organisms EXCEPT: - examination of the fossil record for evidence of common ancestry; - similar amino acid sequences in proteins; - similarities in life cycle and development; - morphological similarities due to convergence; - similar DNA sequences.
20+ years ago, the view of paleontologist and paleoanthropologist on the human evolution is linear/step-ladder where in one specie first then become extinct and then new species came out. Is this true? Explain well and give examples.
Structures in two different species may be similar because of either of two very different reasons. Describe these two reasons. You must use all four of the following terms in your explanation: homologous structures, analogous structures, convergent evolution, and divergent evolution
Members of two different species possess a similar-looking structure that they use in a similar way to perform about the same function. Which of the following would suggest that the relationship more likely represents homology instead of convergent evolution? a. The two species share many proteins in common, and the nucleotide sequences that code for these proteins are almost identicalb. The two species live at great distance from each otherc. The structures in adult members of both species are similar in sized. Both species are well adapted to their respective environments
(top or bottom) Species A, B, C, D, and, E are all extant species (living today; not to be confused with “extinct” species). Consider the common ancestor shared between humans and species A (ancestor A-H), the common ancestor between species B and humans (ancestor B-H), etc. Which of thetwo trees below best represents the phylogenetic relationship between species shown in the nucleotide divergence plot above (top tree or bottom tree)?
Explain the difference between macro and microevolution including how (or if) either (or both) are reflected in the fossil record. Also, within your explanation provide examples of each. Explain the early ideas/foundations/paradigms of the theory of evolution. Be specific and thorough with your answer. Describe the 'evolution of the idea of natural selection. Be specific and thorough with your answer. Describe the conditions or circumstances when organic material (i.e. living things) would not be preserved.
DNA-sequencing studies for a gene in two closely relatedspecies produce the following numbers of sites that vary:Synonymous polymorphisms 50Nonsynonymous polymorphisms 20Synonymous species differences 18Nonsynonymous species differences 2Does this result support neutral evolution of the gene?Does it support an adaptive replacement of aminoacids? What explanation would you offer for theobservations?
Through _______, a body part of an ancestor is modified differently in different lines of descent. a. homologous evolution b. morphological convergence c. adaptive divergence d. morphological divergence
Imagine that you have the DNA sequences fromthe intron of a gene in three species called A, B,and C. Species A and B are most closely related,while C is more distantly related. The sequencesof A and B differ by 18 base pairs, A and C differby 26 base pairs, and B and C differ by 28 basepairs. Fossils show that species A and B divergedabout 1.2 Mya, but there is no fossil evidence asto when the most recent common ancestor ofall three species lived. Use the genetic data toestimate that date. What assumptions are youmaking to get this estimate?
Describe the evidences to support evolution. Given -Homologous features -Analogous features -Determining relationships from similar features -Molecular biology -Biogeography -Fossil record Please answer all of this, please. Thank you
These (1) are remnants of what was once useful to the ancestors of the species. Furthermore, we can infer from the distribution of related species across the Earth the connections between ancient landmasses. Finally, through (2) evidence found in the DNA, we have observed conserved genes and traceable mutations that tell us the phylogenetic relationships of life on earth.
Scientists often talk about the evidence for evolution. Using the five types of evidence listed here, explain how each suggests the occurrence of evolution: 1) structural homologies, 2) molecular homologies, 3) developmental homologies, 4) fossils (general) and 5) transition fossils.
