Evidence for Evolution Worksheet Directions: Read each passage. Based on the reading, answer the questions using complete sentences. Scientists and crime solvers have something in common They can both figure out what happened, even if no one was there to see it They look for clues. The more clues that were left behind the more likely they are to figure it out. If all of the clues point to the same conclusion, then they know what happened Scientists have been gathering evidence for evolution for many years by looking at many different areas of science Below ve five meas of science that are discussed Paleontology shows us that organisms have changed gradually over time as reflected in the fossil record Biogeography shows us how new species anse near the location of very similar species. Similar species share a common time and place. Developmental biology shows us that an organism builds on ancestral features as it develops from a single cell or embryo Morphology shows us how organisms adapt ancestral features to new uses even when there are more efficient solutions elsewhere in natur Genetics shows us that we can group related species by the similanty of genes present in their genomes 1. How are scientists like crime solvers? 2. What are the five areas of science mentioned that have evidence for evolution?

Defend or refute the argument that the government has too large a presence in the agriculture industry.

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.
