This Spiral Timeline Shows the History of Life on Earth
The Earth has evolved throughout billions of years to become the ground we walk on today. Since the earliest start of organic material 3 billion years ago, this spiral timeline, created by the United States Geological Survey (USGS), charts how life has evolved through different periods of time.

The Precambrian period is known by scientists as the earliest part of Earth’s history. During this time, continents began to form and an atmosphere that could harbor life. Early multi-celled creatures developed like worms and jellyfish. You can see in the visualization how life began to really start to flourish from the Precambrian into the Cambrian period which lasted about 55.6 million years. It is also the first time that the first vertebrates, fish, appeared in fossils.
Next came the Ordovician period. This period lasted for about 45 million years and saw modern sea life start to form. Next came one of the shortest periods in terms of evolution, the Silurian Period which only lasted about 28 million years. During this time a warm climate and high sea level allowed coral reefs and sponges to thrive. This spiral graph shows the next periods of life from the Devonian period, Mississippian period, Pennsylvanian period, Permian period, Triassic period, and Jurassic period. This may be one of the most familiar periods because everyone knows and loves the dinosaurs. What you may not know is that dinosaurs actually made a comeback during this period after they nearly went extinct at the end of the Triassic period. The Jurassic period also saw the development of oysters, crabs, lobsters, crocodiles, sharks, and bony fish. This graphic brings us all the way up to the Holocene Epoch period which is the most current period in Earth’s history.

Exploring Science Fiction Technology That Became a Reality
Science fiction often features futuristic technology that once seemed unimaginable. Yet, many sci-fi stories have accurately predicted innovations that eventually became real. Throughout history, countless fictional inventions have transitioned from mere ideas to actual advancements. This fascinating work from AI PRM illustrates the time gap between when these imaginative concepts first appeared in fiction and when they were finally brought to life.

Their research examined sci-fi technology that exists today in these categories:
- Space Exploration
- Communication
- Robotics and AI
- Health and Biotechnology
- Weapons and Defense
When the 1927 film Metropolis became a hit, it was difficult to imagine that the video calls in the movie would ever become a reality, but today, this is a commonplace technology we rely on. The team shows us that the first real-world video phone was created by AT&T in 1964. In 2003, Skype made video calls widely accessible.
As for artificial intelligence in our lives, E.M. Forster’s The Machine Stops depicted a world where people had automated phones that could respond to their commands and help them manage their lives. This became a common trope in science fiction, but today, with the rise of devices like Alexa and Google Home, this technology doesn’t seem unusual at all. Believe it or not, when Jules Verne’s Twenty Thousand Leagues Under the Sea was released in 1870, submarines seemed like a feat of imagination to the reading public. But the Nautilus was inspired by a French sub prototype. The first submarine was launched just a few years later by Isaac Peral in 1888. Explore more technology once thought impossible throughout the team’s article.

Timeline Charts the Development of Communications Technology
Humans are unique because of our sophisticated ability to communicate with one another. What we’re doing right now is a perfect example. Chartistry is showing you the timeline created by the Ooma team who used data from universities and libraries to create a visual representation of changing communications technology. They communicate it to us through pictures and words expressed through pixels, brought to us all by the connective power of the Internet, allowing you to learn something new in a matter of minutes. That alone is an impressive feat of communication! So, how did such a complex system of communication become commonplace? Well, this timeline shows us. A series of pivotal inventions and developments brought us from the first cave paintings to the 5g phone in your pocket.

The timeline starts in 100,000 BC and takes us all the way to present day, highlighting the most important communications technology with an image of each development, a description of why it made an impact, and the date it emerged. Along this long, winding path, we find inventions like the printing press. This creation allowed the written word to spread further and inspired more humans to learn to read. The telegram emerged centuries later inspiring the revolutionary first telephone in 1876.
After the telephone, radio waves opened all new avenues of communication by ushering in the age of radio broadcast and television, allowing humans to keep up with news all over the world. This concept was, of course, perfected by the Internet connecting humans on a global scale. This timeline highlights how deeply humans are driven to connect with each other.

The Evolution of Baby Names: A Century of Trends
Even though approximately 10,000 babies are born each day, the act of naming holds significance. Some parents want a unique name for their child, while others want to follow tradition. Names serve as a window into the cultural zeitgeist, reflecting societal values, historical events, and pop culture influences of their time.
This chart from Kremp shows us that over the past century, we’ve witnessed a fascinating metamorphosis in naming preferences. In the 1920s, traditional monikers like John, William, and Mary dominated the charts, often inspired by religious figures or historical figures. Fast forward to 2023, and we see a shift towards more diverse options such as Liam, Noah, Olivia, and Emma.

This evolution could reflect broader societal changes. The decline of once-ubiquitous names like John and Mary might indicate a move away from strict religious influences while the rise of names like Mateo and Luna suggests an increasing embrace of multiculturalism.
Interestingly, some names have displayed remarkable staying power. James, for instance, has maintained its popularity across generations, briefly falling out of favor only to resurge in recent years.
The world of girl names has seen even more dramatic shifts. The top names of 2023 are notably different to those of a century ago. As we examine the trends Kremp showed us on their colorful and fun chart, remember that names show us what parents valued when gifting their child with their name. Whether drawing inspiration from beloved fictional characters, honoring family traditions, or simply choosing a name that resonates, naming continues to be a deeply personal and meaningful act.
