<ul>
<li><strong>Mutation</strong>:</li>
<li>Introduces new alleles into a population</li>
<li>Can be harmful, beneficial, or neutral</li>
<li>Mutation rate is influenced by various factors</li>
<li><strong>Gene Flow</strong>:</li>
<li>Transfer of genes between populations due to migration and interbreeding</li>
<li>Enhances genetic diversity within a population</li>
<li><strong>Genetic Drift</strong>:</li>
<li>Random changes in allele frequencies due to chance events</li>
<li>More significant in small populations</li>
<li>Founder effect and bottleneck effect</li>

<hr>
<main>
<ul>
<li><strong>Allopatric Speciation</strong>:</li>
<li>Geographic isolation leads to the formation of new species</li>
<li><strong>Example</strong>: Islands or physical barriers separating populations</li>
<li><strong>Sympatric Speciation</strong>:</li>
<li>Speciation occurs within the same geographic area</li>
<li>Due to factors like polyploidy, habitat differentiation, or sexual selection</li>
<li><strong>Parapatric Speciation</strong>:</li>
<li>Occurs when populations are separated by an extreme change in habitat</li>
<li>Limited gene flow between populations</li>

<ul>
<li><strong>Convergent Evolution</strong>:</li>
<li>Unrelated organisms evolve similar traits due to similar selective pressures</li>
<li><strong>Example</strong>: Wings of bats and birds for flying</li>
<li><strong>Divergent Evolution</strong>:</li>
<li>Related species evolve different traits due to different selective pressures</li>
<li>Leads to the formation of new species</li>
<li><strong>Example</strong>: Ancestral mammals diversifying into various groups</li>
