	Purpose of New Cells

	<ul>
		<li>Growth: Just like how you grew taller since last year!</li>
		<li>Maintenance: Like fixing a broken toy, cells replace old, worn-out ones.</li>
		<li>Reproduction: Passing on traits to the next generation.</li>
	</ul>
	</li>
	<li>
	Fun Fact: The cell that divides is the &quot;mother cell&quot; and the resulting cells? They&#39;re called &quot;daughter cells&quot;. The twist? The mother cell doesn&#39;t stay around like human parents do. Instead, it morphs into two new cells!
	</li>
</ul>

<ul>
	<li>
	Core Concept: New cells come ONLY from existing cells dividing. Think of it as a cake that was split to make two smaller cakes 🍰➡️🧁🧁.
	</li>
	<li>
	Evidence: Scientific studies and observations support this.
	</li>
	<li>
	Mind-blowing Implication:

	<ul>
		<li>All cells in our body trace back to one cell, called the zygote. It&rsquo;s like the starting point in a massive relay race.</li>
		<li>This zygote is formed by the fusion of a sperm (from Dad) and an egg (from Mom). Think of it as the ultimate collaboration project!</li>
	</ul>
	</li>
</ul>

<ul>
	<li>Your Origin Story
	<ul>
		<li>Your cells &rarr; Your zygote &rarr; Your parents&#39; sperm and egg cells (from their cell division) &rarr; Your parents&#39; zygote &rarr; their parents &rarr; and so on.</li>
	</ul>
	</li>
	<li>Historical Twist: If we embrace the idea of evolution, it means that:
	<ul>
		<li>Human cells trace back to our ancestors&#39; cells.</li>
		<li>This journey doesn&#39;t stop there. Our cell lineage goes back hundreds of millions of years to the very first cells on Earth!</li>
	</ul>
	</li>
	<li>Real World Example: Imagine a family tree. Except, instead of grandparents and great-grandparents, you have previous cell generations branching out. So, the tree of life starts from the root (the earliest cells) and leads up to you, one of its many leaves!</li>
</ul>

Every cell in your body is a part of an epic saga that spans billions of years. From the dawn of life on Earth, through every ancestor you&rsquo;ve ever had, right to you reading these notes. You&#39;re not just a drop in the ocean; you&#39;re a continuation of the most ancient lineage! So, the next time you look at your hand, remember, the cells in it have a history that&#39;s older than the dinosaurs! 🦖🌍.
