What does the illistration below represent in the context of evolution? $ K five different species sorted from the least evolved one (left) to the most evolved one (right) a sequence of evolutionary steps, from chimps to humans, showing possible intermediate forms five different species, some extant and some extinct, each one descendant from a different ancestor five different species, some extant and some extinct, all likely descendants from a common ancestor

How are transitional fossils evidence to support the process of natural selection? They show that most species have not changed over long periods of time. They show plants and animals that once existed but do not exist now. They show intermediate steps in the evolution process. They show that every species of animals developed separately.

Which of the following does NOT provide evidence for the theory of evolution?     the existence of homologous and vestigial structures     structural and chemical homologies     recorded observations of an individual organism in a population     fossils     presence of DNA in all organisms

30. The theory of evolution is supported by multiple sour and by a variety of fields of study. True or False Refer to the figure shown here. Which of the following would have been a selective agent or pressure that could lead to the reduction in hindlimbs through time? Present 10 MYA 20 MYA 30 MYA 40 MYA 50 MYA 60 MYA False p Modern toothed whales The reduced hind limbs of Rodhocetus kasrani could not have alded it in walking or swimming. Rodhocetus swam with an up-and-down motion, as do modern whales. Hypothetical mesonychid skeleton www M Ambulocetus natans probably walked on land (as do modern sea lions) and swam by flexing its backbone and paddling with its hind limbs (as do modern otters).

We are sure that our closest living relatives are chimpanzees. There is a saying that that humans evolved from chimpanzees. Explain why this is not an accurate view of human evolution. In your answer: • be sure to indicate what misconceptions about evolution this view illustrates, and explain why there are physical similarities and differences between humans and chimpanzees (do NOT list the differences, just explain why/how they exist).

Using examples, explain how FIVE of the following support the modern theory of evolution. (i) homologous structures (ii) analogous structures (iii) vestigal structures (iv) fossil record (v) biogeography (vi) embryology (vii) molecular biology

Vestigial structures are: structures that were helpful to our ancestors but do not serve any useful purpose under current conditions structures that are only helpful when there is competition for survival structures that are harmful relics of our evolution structures that appear to contradict our understanding of how evolution works O000

The American flying squirrel and the flying phalanger of Australia live in similar environments and look very similar. However, they are not closely related. What type of evidence of evolution this refers to? *       Temporal isolation Sexual selection Divergent Convergent evolution No answer

54 in an ELI5 format to answer the question "How does evolution work?" the following topics must be included in your explanation: • Types of selection (directional, stabilizing, disruptive, sexual) • Evolutionary change without selection (Genetic drift, gene flow, genetic bottlenecks, founder effect) ● Human effects on evolution (1 example) • Speciation isolation mechanisms (prezygotic, postzygotic) Speciation (allopatric, sympatric)Patterns of evolution (Adaptive radiation, divergent, convergent, coevolution) .
