The discovery of the oldest known fossil of a singing cicada, Eoplatypleura messelensis, in Germany has significantly expanded our understanding of these ancient insects. The fossil, dating back approximately 47.2 million years to the Eocene epoch, reveals that cicadas were producing music long before humans even existed on Earth. This finding pushes back the timeline for when cicadas began to sing by about 17 million years and offers valuable insights into the evolution of insect communication.
The fossil, which had been in the collection of the Senckenberg Museum since 1986, was initially identified as a cicada fossil in 1988. However, it wasn’t until Hui Jiang, a specialist in singing cicadas, joined the museum that the team decided to study the collection of cicadas. Using digital tools like ZBrush, Maya, and Photoshop, Jiang and her colleagues were able to create a 3D model of the cicada’s shape based on the fossil evidence. The striking color patterns of the ancient cicada likely helped camouflage them on tree trunks.
Surprisingly, Jiang discovered not just one, but two singing cicada fossils from the Eocene. Both adult female specimens were preserved in oil shale, which helped retain delicate details. The fossils, found at the Messel Pit near Darmstadt, Germany, measured about 26.5 millimeters in length with a wingspan of 68.2 millimeters. Analysis of their wing vein patterns revealed that they belonged to the Platypleurini tribe, a group of modern singing cicadas that previously had no fossil record.
Cicadas are known for producing some of the loudest sounds among all insects, with only male cicadas typically singing. The discovery of the two fossilized Platypleurini females from the Eocene offers valuable insights into the history of these insects’ songs. Earlier fossils from different cicada groups had suggested that cicadas began singing around 30 million years ago.
The significance of finding these ancient cicada fossils in Germany lies in the fact that scientists had previously believed cicadas only spread into Eurasia after the collision of Africa and Eurasia’s tectonic plates around 30 to 25 million years ago. However, the discovery of these fossils in Germany indicates that cicadas were present in the region much earlier than previously thought. The estimated past climates of the Messel area, which averaged around 22 °C (71.6 °F), suggest that it provided a suitable habitat for cicadas 47 million years ago. Platypleurini cicadas that exist today thrive in similar temperatures in tropical and subtropical regions of Africa and Asia.
Daniel Pauvik, an insect ecologist at Bowling Green State University in Ohio, emphasized the importance of this discovery, noting that the cicada family is poorly represented in the fossil record. The finding of these ancient cicada fossils provides crucial information about the evolutionary history of these fascinating insects and sheds light on their early communication methods. The Eocene epoch is a crucial period in Earth’s history that marks the beginning of many different groups of animals that are still present today. According to paleontologist, Pauvik, this era is significant as it saw the emergence of various insects, birds, and even reptiles.
One fascinating discovery from the Eocene epoch is the Platypleurini cicada fossil. This particular finding sheds light on the early origins of the entire group of cicadas in that specific region of the world. Pauvik suggests that this discovery may provide insights into the origins of cicadas on a global scale.
The Eocene epoch was a time of great change and evolution in the natural world. It was during this period that many modern animal groups began to take shape and diversify. Insects, birds, and reptiles all started to emerge and establish themselves as dominant species on Earth.
The Platypleurini cicada fossil is just one example of the many incredible discoveries that have been made from the Eocene epoch. This finding not only provides valuable information about the early origins of cicadas but also offers a glimpse into the broader evolutionary history of insects as a whole.
Overall, the Eocene epoch is a critical time in Earth’s history that laid the foundation for many of the animal groups that we see today. By studying fossils from this period, scientists can gain a better understanding of how these groups evolved and diversified over time. The Platypleurini cicada fossil is just one piece of the puzzle, but it is a significant one that helps to illuminate the early origins of these fascinating insects. The global pandemic caused by the spread of COVID-19 has changed the way we live our lives in many ways. From wearing masks in public to practicing social distancing, the virus has forced us to adapt to a new normal. However, one of the most significant changes that has occurred as a result of the pandemic is the shift towards remote work.
Remote work, also known as telecommuting, has become increasingly popular as companies have had to adjust to stay-at-home orders and social distancing guidelines. Many businesses have transitioned their employees to remote work in order to keep them safe and prevent the spread of the virus. This has led to a major shift in the way we think about work and the workplace.
One of the biggest benefits of remote work is the flexibility it offers. Employees no longer have to commute to the office, saving them time and money. This has led to a better work-life balance for many workers, as they are able to spend more time with their families and pursue personal interests. Additionally, remote work allows employees to work from anywhere, giving them the freedom to live in locations that suit their lifestyle.
Another advantage of remote work is increased productivity. Without the distractions of a busy office, employees are often able to focus more on their work and get more done in less time. This has been a major benefit for many companies, as they have seen an increase in productivity since transitioning to remote work.
However, remote work does come with its challenges. One of the biggest challenges is communication. Without the ability to have face-to-face interactions, it can be difficult to collaborate with colleagues and stay connected as a team. Many companies have had to invest in new technology and tools to facilitate communication and collaboration among remote workers.
Another challenge of remote work is maintaining a sense of company culture. Without the camaraderie of an office environment, it can be challenging to foster a sense of community among remote employees. Many companies have had to find creative ways to keep their employees engaged and connected, such as virtual team-building activities and online social events.
Overall, the shift towards remote work has been a major change brought about by the COVID-19 pandemic. While there are challenges to overcome, the benefits of remote work are clear. As we continue to navigate the uncertainty of the pandemic, remote work is likely to become a more permanent fixture in the way we work. This shift towards remote work has the potential to revolutionize the way we think about work and the workplace, making it more flexible, productive, and inclusive for all. The world of technology is constantly evolving, with new innovations and advancements being made every day. One of the most exciting developments in recent years is the rise of artificial intelligence (AI). AI is a branch of computer science that aims to create machines that can perform tasks that typically require human intelligence, such as learning, reasoning, and problem-solving.

In healthcare, AI is being used to diagnose diseases, develop personalized treatment plans, and improve patient outcomes. In finance, AI is being used to detect fraud, make investment decisions, and automate customer service. In transportation, AI is being used to optimize traffic flow, improve safety, and develop self-driving cars.
One of the most promising applications of AI is in the field of robotics. Robots powered by AI have the potential to revolutionize many aspects of our lives, from manufacturing to household chores to healthcare. In manufacturing, AI-powered robots can work faster and more efficiently than human workers, leading to increased productivity and lower costs. In household chores, AI-powered robots can clean, cook, and even provide companionship for the elderly or disabled. In healthcare, AI-powered robots can assist doctors in surgeries, monitor patients, and provide emotional support.
However, the rise of AI also raises ethical and social concerns. One major concern is the potential impact of AI on jobs. As AI becomes more advanced, there is a fear that robots will replace human workers, leading to mass unemployment. Another concern is the issue of bias in AI algorithms. Since AI learns from data, it can perpetuate existing biases and discrimination. For example, AI-powered hiring systems may discriminate against certain groups of people based on race or gender.
Despite these concerns, the potential benefits of AI are too great to ignore. With the right regulations and safeguards in place, AI has the potential to improve our lives in countless ways. From improving healthcare outcomes to increasing productivity to enhancing our quality of life, AI has the power to transform our world for the better. As we continue to push the boundaries of what is possible with AI, it is important to keep in mind the ethical implications and ensure that AI is used responsibly and ethically.
