<ul>
<li>Peppered moth evolution in response to industrial pollution
<ul>
<li>Light-colored moths became less common due to increased visibility to predators</li>
<li>Dark-colored moths became more common as they were better camouflaged on polluted trees</li>
</ul>
</li>
<li>Darwin’s finches in the Galapagos Islands
<ul>
<li>Different species of finches evolved from a common ancestor due to adaptations to different food sources on different islands</li>
</ul>
</li>
<li>Antibiotic resistance in bacteria
<ul>
<li>Overuse and misuse of antibiotics led to natural selection favoring bacteria with resistance genes</li>
<li>Examples include MRSA (methicillin-resistant Staphylococcus aureus) and antibiotic-resistant tuberculosis</li>

<ul>
<li>Lamarck’s theory of inheritance of acquired characteristics
<ul>
<li>Organisms can pass on traits acquired during their lifetime to their offspring</li>
<li>Example: Giraffes stretching their necks to reach leaves and passing on longer necks to their offspring</li>
</ul>
</li>
<li>Darwin’s theory of natural selection
<ul>
<li>Individuals with advantageous traits are more likely to survive and reproduce</li>
<li>Their offspring will inherit these traits, leading to the accumulation of beneficial adaptations over time</li>
</ul>
</li>
<li>Modern synthesis of evolutionary theory
<ul>
<li>Combines Darwin’s theory of natural selection with Mendelian genetics and modern understanding of DNA</li>
<li>Emphasizes the role of genetic variations and mutations in evolution</li>
