Give typing answer with explanation and conclusion to all parts What evidence shows that the most recent common ancestor of chimpanzees and humans was much more arboreal than modern humans are? We spoke of paleoenvironmental processes that changed the ecological environmental conditions in Africa somewhere around 7 million years in Africa: which are they? How would have these processes might have selected for a less arboreal lifestyle in the human lineage? Why did the same changes not evolve in the chimpanzee lineage?

You have found fossils of a new species of ape that walks upright. After 11 additional years in the field, you discover a fossil of what you think is the common ancestor of the new species of ape and all other gorillas. What types of data would give you the best information on the environment of this ancestral organism? anatomical features of the new species of ape fossils of plants and animals found with the fossilized common ancestor gene sequencing of the new species of ape anatomical features of the fossilized common ancestor behavior of the new species of ape

Eyes are often used in arguments for intelligent design because many consider this organ to be too complex to have evolved by chance alone. However, complex lensed eyes evolved independently both within cephalod mollusks and vertebrates including our own ancestor. In the evolution of these structures the corresponding phylogenies revealed that both:     A) were preceded by the evolution of 'simple' light sensing eyes, thus having adaptive intermediate evolutionary steps.     B) lacked intermediate evolutionary steps involving the evolution of 'simple' eyes.     C) had intermediate evolutionary steps, but ultimately the vertebrate eye had a superior 'design' without any kind of blind spot, relative to the simple invertebrate cephalopod eye.     D) were preceded by vestigial non-functional optic structures.

The presence of tiny hairs, called setae, on the toe pads of some geckos is associated with the ability to adhere to smooth surfaces. This ability allows geckos to climb in areas where many predators cannot. Scientists studying the evolution of setae have identified three closely related species of gecko, only one of which can adhere to smooth surfaces.. A model of the evolutionary relatedness between these species is represented in the figure. G. humeralis 1 Can adhere OG. concinnatus O Cannot adhere O G. antillensis Which of the following statements is an accurate description of the evolutionary relationships shown in the model? G. concinnatus is more closely related to G. antillensis than to G. humeralis. DNA nnd protein segienci in common with G humeralis than with G concionatus

Give typing answer with explanation and conclusion to all parts 1. What are the wings of birds and bees are an example of? 1. a homologous character 2. convergent evolution 3. derived characters 4. mosaic evolution 5. ancestral characters

Some organisms have features that have different functions, but similar structures. One example is the forelimb of humans, dogs, birds, and whales. What term best describes the relationship between these structures? * Embryological Analogous Homologous no answer Vestigial Which of the following is NOT true about creationism? * no answer There is no extinction of organisms because organisms can always survive as long as they try hard enough. The earth was created only 6000 years ago because the evidence of the rocks support that idea. Any great change is due to small but cumulative changes that occur over long periods of time. All organisms are perfect because they are created to be able to survive in their habitat.

Select True or False for each of the following statements: a.If chimpanzees like those studied at Gombe by Jane Goodall are used as a model for early humans, the focus is on females and their offspring, whom they share food with, and this bond is the stable core of the society. b. From the Science article you read, the evidence found at sites on Calvert Island support the Ice Free Corridor hypothesis. c. Analysis of DNA extracted from fossils found at Denisova Cave, Siberia, suggests that Denisovans interbred with Neanderthals, who took some Denisovan DNA with them when they moved into Europe. d. It is possible that the lack of symbolic artifacts in Neanderthal culture is due to the fact that their brains matured more slowly than modern humans’ brains, and they never reached mental adulthood. e. From the video clip "Becoming Human", early bipedal hominins like Australopithecus afarensis were very ape-like from the waist down, and very human-like from the waist up.

A one or two sentence explanation is all that is needed for the mutiple choice question in Picture

Scientists have long believed that the 14 species of finches on the Galapagos Islands evolved from a single species of finch that migrated to the islands one to five million years ago. Recent DNA analyses support the conclusion that all of the Galapagos finches evolved from the mainland warbler finch. Different species live on different islands. One of the major changes in the finches is in their beak sizes and shapes. How would an evolutionary biologist today best answer the following question? How did the different beak types first arise in the Galapagos finches?   A. Changes in the finches' beaks occurred by chance, and when there was a good match between beak structures and available food, those birds had more offspring.   B. The changes in the finches' beaks occurred because the environment induced the desired genetic changes.   C. The finches' beaks changed a little bit in size and shape with each successive generation, some getting larger and some getting…

Some human traits may have arisen by sexual selection. Over thousands of years, women attracted to charming, witty men perhaps prompted the development of human intellect beyond what was necessary for mere survival. Men attracted to women with juvenile features may have shifted the species as a whole to be less hairy and softer featured than any of our simian relatives. Can you think of a way to test this hypotheses?
