- Humans as individuals have a number of disadvantages compared to other animals. For instance we are not very fast, strong, cannot see well in the dark, have a poor sense of smell and hearing compared to other animals, and we are not very good climbers. With all of these disadvantages how is it that we have been so successful? Shouldn't we have gone extinct as other humanoids such as Homo erectus? Discuss why humans have beaten the odds and are so successful.Explain why the statement that a monkey is more evolved than a mouse is incorrect.The word invertebrate is so broad that it describes 95 percent of all living animal species. Do you think the term invertebrate is too broad to be useful to scientists? Give reasons to support your answer.
- Which of the following is a correct way to distinguish reptiles from amphibians? a. Reptiles have scales & amphibians don't b. Amphibians lay eggs and reptiles don't c. Reptiles sometimes don't have legs, but amphibians always have them. d. Reptiles go through metamorphosis and amphibians don't e. Reptiles lay eggs and amphibians don'tUse the scenario to answer the question. 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 causation. It shows evidence of climate change. It shows evidence of widespread expression.Birds are supposed to be the dinosaurs' closest relatives. List and explain five reasons why the Aves have been able to adapt (morphological traits) and survive in the ever-changing world we live into this day.
- If you are a scientist studying the evolution of animals, what is the best approach you can use for analysis? analyzing behaviors of living animals with a common ancestry analyzing embryos and skeletons of animals of the same species analyzing DNA sequences and embryonic development analyzing the the fossilized remains of animals from different time periodsThe evolution of which of the following features of mammals is hardest to trace through the fossil record? a. Jaw structure b. Mammary glands c. Middle ear structure d. Development of hairAs we went through Phyla in the animal kingdom, the animals become more and more complex in their body organization. Be able to explain two trends you noticed and how these adaptations would benefit the organism. Use specific organisms and features in your answer.
- Pick two organisms from the cladogram below and make a claim about the evolutionary relationship between these organisms. Support your claim using evidence from the lesson and scientific reasoning about evolutionary relationships. Ray-finned fish Rodents Sharks Amphibians Primates & rabbits Crocodiles Birds Hair Eggs with shell Amniotic egg Four limbs Bony skeleton Vertebrae Image Source a relationship betwwen a shark and bird is a bony skeleton amitotic egg and four limbsHumans are heterodonts, which means they Group of answer choices have different types of teeth multiple phalanges on the hands and feet are related to elephants two collar bonesUse the information and diagram to answer the following question. In humans, the pelvis and femur are involved in walking. Despite the fact modern whales live in water, they contain a pelvis and femur that are common in land dwelling animals. 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? A. They are newly developed structures found in modern whales due to mutations. B. They are examples of fossilized remains of ancient organisms. C. They are traits acquired by modern whales over time as they adapted to living in water. D. They are vestigial structures which are remnants of structures that served a function in the organism’s ancestors.
