- Species Embryo (A-F) Describe the Anatomical Changes from Early to Late Stages Human Chicken Rabbit Tortoise Salamander В Fish A Guide Questions: 1. Look again at the six embryos in their earliest stages. Describe the patterns you see. What physical similarities exist between each of the embryos? 2. Does this suggest an evolutionary relationship? Explain how these embryos can be used as evidence of a common ancestor between each of these six organisms.Please answer fast 1. When a researcher states that two sequences share a conserved region, what principle isinvoked? a. the sequences are homologousb. the sequences are similarc. the sequences share the same functiond. the sequences are homogenous 2. Local sequence alignment algorithms are a better choice than global sequence alignmentfor a. finding homologous DNA elements among distantly related organismsLocal sequence alignment algorithms are a better choice than global sequence alignment b. finding homologous DNA elements among closely related organisms 3. Which of the following sequence alignment programs work by doing local alignments? a. BLASTb. Clustalc. MUSCLEd. T-Coffee 4. The difference between local and global sequence alignments is that local alignmentalgorithms attempt to a. align arbitrary-length segments of the sequencesb. align every residue in every sequenceRead This! Extensive research has been done to find similarities and differences in the DNA sequences of different an- imals. This work is very difficult and time consuming, but it can help biologists determine the evolution- ary ancestry of a species. For example, when investigating the human genome, biologists found that about 99.5% of the DNA sequences among humans are the same. Considering the wide variety of traits in the human population, we are a lot more similar than we are different. Humans share approximately 96% of their DNA sequences with chimpanzees, 85% with mice, and 75% with chickens. 16. Study the table below. Organism Pair Percentage of DNA Similarity A-B 97 A-C 85 A-D 50 a. To which organism, B, C or D, is organism A most closely related? Support your answer. b. Which pair of organisms in the table is least closely related? Support your answer. c. Which pair of organisms most likely shares a recent common ancestor?

Scoring Rubric 4 noints intsHello, I need help answering 5c & 5d using the phylogeny below(letter (A) graph to the left). Pls and thank you! a) In the 1990s, when only mitochondrial DNA sequencing was available, geneticists claimed that there was no hybridization between humans (Homo sapiens) and Neanderthals (Homo neanderthalensis). Does the phylogeny shown above support the claim humans did not hybridize with Neanderthals in the past? How can you tell? b) Once nuclear DNA sequencing became fast and able to handle sequencing ancient DNA, living humans were found to have some Neanderthal genes. Is this finding clear evidence that some early modern humans did indeed hybridize with Neanderthals? Why? c) Did female H. sapiens hybridize with Neanderthal males to produce fertile offspring that then back-crossed with modern humans? What does the graph say about this? d) Did male H. sapiens hybridize with Neanderthal females that then back-crossed with modern humans? What does the graph say about this?…Among a large number Of Git homones only a handful have been well characterized brielly discuss aboul them.

These are structures that have been reduced to the point that they are virtually useless. Ear muscles and the tail bones are examples of vestigial structures in our own species. Explain how vestigial structures provide clues about a species' evolutionary past. Illustrate your argument with vestigial structures found in humans or other real species.Because the Laetoli footprints date to 3.6 mya and they are clearly made by a bipedal hominin, it is likely that they were made by Australopithecus afarensis, who appears to have been the only hominin around at that time.
