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.

Question 2U Which is NOT an example of homoplasious characters? A More than one of these. B Bats and birds are both monophyletic groups with wings. Many species of insects, amphibians, and fish have evolved red and yellow warning coloration to advertise their poisonous skin or organs. Sharks and dolphins have fins and fuselage-shaped bodies, despite sharing a distant common ancestor.

Genomics and Human Evolution The Denisovan genome contains sequences that originated from an unknown human species. Using Figure 19.11, speculate on which species this might be. Is it possible that there are other ancestral species that may remain to be discovered that would change the phylogeny presented in the figure? FIGURE 19.11 Estimates for the dates of origin and extinction for the three main groups of hominins (green, blue, and orange). The australopithecines split into two groups about 2.7 million years ago. One of those groups, the genus Homo, contains the ancestors to our species, H. sapiens.
QUESTION 3 What is the role of fossils in supporting the theory of evolution? There have been many fossils of intermediate types discovered that provide strong support for the theory of evolution There are not enough fossils to support this theory Fossils of dinosaurs show that other types of life existed, but there is no evidence of relationships between them There are plenty of fossils to show that animals have evolved, but there are not enough fossils of human ancestors to suggest that humans are related to other animals

48. During the late Cretaceous Period, the quadrupedal dinosaur Triceratops horridus (fossils dating from 68.0 to 67.0 MYA in Wyoming's Lance Creek Formation) evolved into the heavier Triceratops prorsus (fossils dating from 67.0 to 66.0 MYA in Montana's Hell Creek Formation), with no apparent branching of additional species in this lineage. The gradual disappearance of one light ancestral species (Triceratops horridus), and its gradual replacement by one heavier descendant species (Triceratops prorsus), perhaps in response to the newly-arrived predatory dinosaur Tyrannosaurus rex, in about the same geographic region, is probably an example of: A. disruptive selection leading to branching speciation B. diversifying selection leading to cladogenesis C. directional selection leading to anagenesis D. stabilizing selection leading to stasis E. all of the above

Hello, 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?…
