Nothing says summer like a juicy, cold slice of watermelon. It's the fruit we crave during hot days, offering a perfect balance of sweetness and refreshment. But what if we told you that the watermelon we know today looks vastly different from the original version? According to Australian chemist James Kennedy, watermelon may very well be the most unnatural fruit in the world due to how drastically it has been changed by humans.

1. What Is A Watermelon?

Watermelon (Citrullus lanatus) belongs to the Cucurbitaceae family, which also includes cucumbers, melons, and pumpkins. Today, watermelon is a refreshing treat, known for its high water content (around 90%) and its vibrant, red flesh filled with black seeds, though seedless varietiesare becoming more common.

Nutritional Value Of Watermelon

In addition to its water content, watermelon provides vitamins A and C, antioxidants like lycopene, and dietary fiber, making it both a nutritious and hydrating option. But watermelon wasn’t always the sweet, juicy fruit that we know and love today.

Its transformation into the watermelon we buy at the grocery store is the result of centuries of cultivation and selective breeding, driven by both necessity and human desire for a better-tasting fruit.

2. The Origins Of Watermelon

Watermelon’s journey began in Africa, where its wild ancestor, Citrullus lanatus var. citroides, grew in arid climates. These early watermelons were small, bitter, and packed with seeds, which made them far less palatable than modern varieties.

Despite the bitterness, they were valuable for their hydrating properties. In places where fresh water was scarce, these wild watermelons served as a natural water reservoir.The first evidence of watermelon cultivation dates back over 4,000 years, with early use recorded in ancient Egypt.

Archaeological finds, including watermelon seeds in King Tut’s tomb, show that the fruit was important not only for hydration but also for its perceived spiritual and cultural significance. Early Egyptians likely cultivated watermelon for its ability to store water over long periods, rather than for its sweetness.

The Spread Of Watermelon

As watermelon spread through Africa and into Europe and Asia, it was gradually selected for different traits, such as size and taste. It wasn’t until the 17th century that watermelon started to gain popularity outside of its native regions, especially once farmers began selecting for sweeter, more edible varieties.

3. How Humans Have Shaped Watermelon

Through centuries of selective breeding, humans transformed watermelon from a small, bitter, seed-filled fruit into the sweet, juicy variety we consume today. Early farmers focused on selecting watermelon plants that produced larger, sweeter, and more easily accessible fruit. This process of cultivating plants for specific traits has drastically reshaped watermelon’s physical characteristics.

The Increase In Size

The watermelon’s size is one of the most dramatic changes. Wild watermelons were often just a few inches in diameter, but over time, they grew to massive proportions. Today, a typical watermelon can weigh anywhere from 4 to 18 pounds, though some record-breaking varieties have reached well over 350 pounds.

In fact, the Guinness World Record for the largest watermelon stands at 350.5 pounds, a testament to the immense size achieved through human breeding efforts.

The Shift In Color And Taste

Watermelon’s color has also changed significantly. Early watermelons were pale and yellowish, but as farmers selected for sweetness, the fruit gradually turned the deep red we associate with modern varieties.

This color change is linked to lycopene, an antioxidant found in watermelon. Today, watermelon contains more lycopene than almost any other fruit, including tomatoes. Research suggests that lycopene may help reduce the risk of heart disease, certain cancers, and even age-related eye disorders.

4. Watermelon’s Genetic Blueprint

While watermelon’s transformation into the fruit we know today is fascinating, the development of seedless watermelon is one of the most significant milestones in its genetic evolution.

The Birth Of Seedless Watermelon

Creating seedless watermelon is no small feat. Watermelon plants normally have 22 chromosomes. However, through a process called chromosome doubling, scientists have been able to create watermelons that have 44 chromosomes.

When these tetraploid plants (with four sets of chromosomes) fertilize normal diploid plants (with two sets of chromosomes), they produce triploid watermelons (with three sets of chromosomes), which are sterile and cannot produce seeds. These seedless varieties are popular for their convenience, as they eliminate the need to remove seeds before eating.

However, this manipulation has raised concerns about the genetic diversity of modern watermelon crops. By focusing on creating larger, sweeter, and seedless varieties, breeders have reduced the genetic pool of watermelon plants, potentially making them more vulnerable to diseases and pests.

5. Natural Vs. Man-Made: The Debate

So, is watermelon natural or man-made? Technically, watermelon began as a naturally occurring fruit. However, its journey through thousands of years of cultivation and breeding has transformed it into a fruit that bears little resemblance to its wild ancestors.

While watermelon’s origins are firmly rooted in nature, its modern form is largely the product of human manipulation. Through selective breeding and the development of genetic techniques like chromosome doubling, watermelon has been transformed into the large, sweet, and seedless fruit we know today.

6. Health Benefits Of Watermelon

Watermelon isn’t just delicious it’s also packed with nutritional value. Beyond being hydrating, watermelon offers numerous health benefits that make it a great addition to a balanced diet.

Key Health Benefits:

• High in Water: Watermelon’s 90% water content makes it an excellent hydrating fruit, especially during hot weather.
• Rich in Vitamins: Watermelon contains vitamin A and vitamin C, both of which play a role in supporting the immune system and promoting healthy skin.
• Lycopene: This powerful antioxidant may help reduce the risk of heart disease and certain cancers. In fact, watermelon has more lycopene per ounce than tomatoes.
• Citrulline: This amino acid, found in watermelon’s flesh and rind, is believed to help lower blood pressure and improve cardiovascular health.

Including watermelon in your diet can also support digestive health due to its high fiber content.

7. The Debate Over Seedless Watermelons

While seedless watermelons are highly convenient, there’s some debate over whether seedless varieties are the best choice for both nutritional and environmental reasons.

Pros Of Seedless Watermelons:

• Convenience: Seedless watermelon is easier to eat, as there’s no need to remove seeds.
• Consistency: Seedless watermelons tend to be more uniform in size and flavor, which is why they are popular in supermarkets.

Nutritional Concerns:

Despite the benefits, some nutritionists argue that watermelon seeds contain essential nutrients, including protein, magnesium, and healthy fats, which contribute to heart health. Eating watermelon seeds, especially when they are sprouted, can add significant nutritional value to your diet.

Environmental And Agricultural Impact:

The heavy reliance on seedless watermelon has led to a reduction in genetic diversity in watermelon crops, which can make them more susceptible to diseases and pests.
