Around 500-million-years ago, all macroscopic life was still living underwater. Animals were still relatively young, and plants still had tens of millions of years to evolve and claim the land. You have probably heard about this time: the Cambrian period. The Cambrian is probably one most popular paleontological eras without dinosaurs (in fact, almost 300…

Ancient languages and ancient forests, how diversity hints history
This summer I had the chance to make two trips that inspired me to write this new post, a post that mixes history, evolution and biogeography. These trips unite both culture and evolutionary concepts, and exemplify how small, even minute outliers in our surroundings can carry the weight of thousands of years, to a time…
Our croaky Gods: frogs across creational myths
Frogs and toads, the Anurans. When Homo sapiens took their first steps across Eastern Africa, and later spread across the globe, anurans were already present in almost every corner of the world. Currently, the relation between humans and anurans is complicated. While we know more about them than we have ever known, our presence and…
Are viruses even alive? 2-Viruses and the definition of life
It is not clear whether viruses are alive or not. All life in this planet follows a series of rules that separate them from non-living beings., but viruses do not seem to follow them, exactly. We reviewed how viruses works and what constitutes life in Are viruses even alive? 1- What is life? Here, we go…
Are viruses even alive? 1- What is life?
Virus literally translates to slime or poison in latin, a sufficient word to define these organisms. It is but a highly simplistic depiction of a much more complex entity. The current coronavirus pandemic is defining everyone’s life. There are thousands of articles and videos talking about coronaviruses, and we encourage anyone to get informed only…
Strangers in the animal tree (FINALE)
It has been a long while since the latest post in Onelephantsandbacteria, but we wanted to complete the series of Strangers in the Animal tree. That may represent a new renaissance on the blog, or at least, another small step to keep it alive. Animals are fascinating examples of life on Earth and their evolutionary…
Prof. Hawking, I respectfully disagree………….about aliens
Prof. Stephen Hawking, who sadly passed away last month, was an example both as a person and a researcher. His work on black holes was praised and respected in the scientific community, and through his constant appearances in shows and documentaries he also became a prominent figure in pop culture of the last 50 years….
The plants of Proxima Centaury
The Blue Planet, the “Pale Blue Dot”, as Carl Sagan put it. That’s our planet, Earth. But not everything is blue on the surface, there is also green, tons of it, a living green. Life may seem complicated at a first glance, but its basic requisites are, in fact, only energy and matter. And organisms have…
The scientific imaginary creatures (III): Snouters and the lost world of Hyi-yi-yi
An undiscovered island… After several days aimlessly wandering in a boat through the Pacific Ocean, Einar Pettersson-Skamtvist, a Swede soldier, finally set foot on an island. His escape from the Japanese prisoner’s camp had been a success. But luck is ephemeral and found himself drifting on a malfunctioning boat. On the verge of starvation and…
The scientific imaginary creatures (II): Floaters and other life in Jupiter
It’s 1980. The decade of the 70’s has come to an end, and with it, a time when space travel seemed to be achievable just in a few decades. Fueled by Apolo’s XI landing in 1969, science fiction had just experimented a sudden rise that had even been promoted to the mainstream media…
