Use the following passage to answer the next two questions. Ducks are aquatic birds. Their feet are webbed and this trait makes them fast swimmers. Biologists believe that ducks evolved from land birds that did not have webbed feet. The amount of webbing on a duck's feet is a heritable trait. Q6.8. While webbed feet were evolving in ancestral ducks, with each generation: Most ducks had about the same amount of webbing on their feet as their parents. Most ducks had more webbing on their feet than their parents. Most ducks had less webbing on their feet than their parents. The amount of webbing on ducks' feet had no relationship with the amount their parents had.

Dolphins and fish have similar body shapes. Is this feature more likely a homologous or analogous trait?
Use 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.
Research shows that Neandertals coexisted with at least three other species, including Homo sapiens. There are some humans today that have Neandertal and Denisovan genes. Generate a hypothesis about how their genes are also a part of our genes.
Which statement is true about the Neanderthals? O A. They originated around the same time period as homo sapiens and coexisted O B. Homo sapiens rapidly killed off all the Neanderthals as they had superior fighting technology like the bow and arrow and spears O C. Neanderthals interbred with Homo sapiens and as a result assimilated with Homo sapiens O D. They were only living in Europe where they had genes allowing them to acclimate to that particular environment. OE. Neaderthals were the likely direct ancestors of the newly discovered pigmy island species of humans, H. floresiensis and H. luzonensis
answer in 5 paragraphs What trait evolved separately three times in the Animal kingdom? Why is this trait favored?
Flight in birds developed over time due to multiple evolutionary steps. The development of feathers, hollow bones, large flight muscles, and efficient gas exchange was vital for flight. Describe the order in which these adaptations likely evolved and explain your reasoning.
Eels have slender bodies that facilitate moving through narrow cracks in rocks when searching for prey. In 2-3 sentences: Provide a scenario describing how and why slender bodies of eels may have evolved, according to the principles of natural selection.
Explain the reason why modern biologists can more easily accept that a mammal can have some reptile- like traits than scientists who were considering this animal in the late 1700s.
Mammals belong to a group of amniotes known as synapsids. Three major lineages of mammals had emerged by the early Cretaceous period. In a tabulated form, compare these three lineages to illustrate their diversity in terms of: a. Embryonic development b. How the young are fed c. Period of gestation
Flight in birds developed over time as a result of multiple evolutionary steps. The development of feathers, hollow bones, large flight muscles, and efficient gas exchange were all vital for flight. Describe the order in which these adaptations likely evolved and explain your reasoning.
ces When Charles Darwin visited the Galapagos Islands, he observed the marine iguana. He later decided that the marine iguana evolved from the terrestrial iguana found on the mainland of South America. The marine iguana differs from the terrestrial iguana in several ways. The marine iguana has a flat tail, long claws and sharp teeth while the terrestrial iguana has a round tail, short claws and flat teeth. The marine iguana became a separate species after being geographically isolated on the Galapagos Islands for several years.
