Darwin's theory of natural selection has long been a guiding light for explaining changes in species over time. These changes happen for a number of reasons and are usually based on selective pressure.Which of the following examples is NOT an instance of natural selection?Elimination ToolSelect one answerAA group of giraffes stretching their necks in order to reach more leaves to eat.BA shift in the coloring of beetles over time to blend in with the leaves.CMore nocturnal mice in an area over time due to the presence of daytime predators.DA group of gophers getting smaller over time because they can hide in caves from predators.

Learning goal 3: Determine which of the following are examples of evolution.White fur becomes common in a population of wolves over thousands of yearsA tadpole turns into a frogA population of turtles develops longer necks over many generationsA dog learns to sit and stay after weeks of training

MULTIPLE CHOICEWhich of the following lines of evidence supports the concept of natural selection?A the strong similarities in the features and traits of organisms found on different continents and isolated islandsB the random occurrence of new traits in a populationC the absence of similarities in DNA sequences among closely related speciesD the existence of transitional fossils shows gradual changes between different species

Which statement gives the best example of natural selection?A A frog has a random gene mutation that changes its color.B A bird makes a loud call to attract a mate.C A lizard sits under shade in a hot desert.D A strain of bacteria has become resistant to antibiotics.
