Based on your observation of the whale diagram and your understanding of evidence that supports evolution, what is TRUE about the pelvis and femur found in living whales today? O A. They are traits acquired by modern whales over time as they adapted to living in water. B. They are examples of fossilized remains of ancient organisms. C. They are vestigial structures which are remnants of structures that served a function in the organism's ancestors. are newly develoned structures found in modern whales due to mutations.

Knowledge of the genomes of ancient homininsmight help us better understand not only the evolutionaryhistory of hominins, but also the traits that differ between usand our relatives—the traits that make us human. Our understandingof the functions of different genes is growing rapidly,so detailed comparisons of our genes to those present in, say,Neanderthals and Denisovans are very revealing. What do youthink are the functions most likely to be related to the geneticdifferences between us and our hominin relatives?
II Pause Q Zoom extinct whale Which of the following is true as the presence of bones is similarly found both in the baleen whale and in the extinct whale? Whales have functional legs that are hidden by fat and skin. B. Whales can travel on land when necessary. c. Whales evolved from four legged animals. Whales are developing into animals with four functioning limbs. 2021 1lluminate EducationTM, Inc.
1 pts Structures as different as human arms, bat wings, and dolphin flippers contain many of the same bones, these bones having developed from very similar embryonic tissues. How do biologists interpret these similarities? O They are homologous. O They are rudimentary. O They are analogous. O They are vestigial.
This West Indian manatee (Trichechus manatus) is an aquaticmammal. Like amphibians and reptiles, mammals are tetrapods (vertebrates with four limbs). Explain why manatees areconsidered tetrapods even though they lack hind limbs, andsuggest traits that manatees likely share with leopards andother mammals (see Figure 26.12b). Discuss how early members of the manatee lineage might have differed from today’smanatees.

. DNA sequences in many human genes are very similar to thesequences of corresponding genes in chimpanzees. The mostlikely explanation for this result is that(A) humans and chimpanzees share a relatively recent common ancestor.(B) humans evolved from chimpanzees.(C) chimpanzees evolved from humans.(D) convergent evolution led to the DNA similarities.
n. Scientists have found one new fossil that is similar to Archaeopteryx. It is only the second fossil of its kind. It shows an animal that had a long-feathered tail and small teeth, like non-avian dinosaurs. But the animal also had flight feathers and wings, like modern birds. The fossil also shows a fused clavicle bone, which confirms the relationship between birds and dinosaurs because they are the only two groups with this characteristic. What is true about this scenario? It shows evidence of evolution. It shows evidence of widespread expression. It shows evidence of climate change. It shows evidence of causation.
56) The human body contains structures that are needed for survival, or in the case of vestigial structures, were needed for survivalL Wisdom teeth, seen here, are vestigial third molars. Human ancestors had larger jaws with more teeth. Over thousands of years, man no longer needed the third molar, and they became the source of dental problems rather than an aid in survival How does this vestigial structure support the theory of natural selection? ht ing The size of man's cranial cavity evolved. With increased cranial cavity size, the size of man's brain also grew. This resulted in a smaller jaw and no 14 A) room for the third molars. Agriculture and the use of fire changed what and how man ate and need for these teeth diminished over time. Jaw size and shaped evolved and there was insufficient room for the third molars. he B) The climate on Earth changed from very cold to tropical The tropical climate on Earth lead to a change in the diet of humans and that lead to the need for sharp,…
Ⓒ Macmillan Learning An extensive study of a hominid fossil dating from approximately 2 million years ago was published in 2013. Determine whether each of the features described is closer to the ancestral state or to the modern human state. The shoulder structure and very long arms suggest the ability to climb and perhaps hang or swing. closer to the modern human state closer to the ancestral state The spine and other skeletal features suggest an upright stance. There is no opposable toe. The skull is very small.

Neanderthals are recognizably human but have distinctive facial features and a stocky build that were evolutionary adaptations to cold, dry environments. They shared Europe for 10,000 years with Homo sapiens. Today they no longer exist. Beyond these facts the fate of Neanderthals has generated much debate. Why did Neanderthalsbecome extinct? State at least two major factors toexplain their fate.
of this =rab or ditions ionary escen- se or 5. Describe two examples of vestigial structures that you can find among the Caminalcules. 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.
