One of the ways to create a major mountain range is a process called subduction. Here, heavy oceanic rock sinks beneath the lighter continental rock. The result--coastal mountain ranges like th...
In marine mammals, there are two different body types for two different niches: A long, strong tail for all-marine whales... ...and all four legs modified into flippers for pinnipeds that fee...
In recent years, the search for the origins of life is becoming complex. It turns out that oxygen is NOT a requirement for multicellular life to thrive. As stated in this BBC article, poriferans ...
This famous tapestry shows all the "modernized" traits of a unicorn--basically just a pale-colored horse with a single horn on its head. Of course, single-horned animals do and did exist: ...
So, in this alternate Europe, there are some obvious differences. First off, the Baltic Sea is no longer a sea, but now the Baltic Plain. Also, the Low Countries are absent entirely. There are...
In relation to a recent question of mine, this alternate Earth still has its core consisting of 84% iron, but the other 16% contains the greatest concentrations of all known species of heavy metals...
Today, dinosaurs, alligators, crocodiles, gharials and caimen are all that remains of a special group of reptiles called the archosaurs. Recently, it has been accepted by the public that birds did...
This scenario is based on the kea, the world's only alpine parrot. Even though it eats plants like other parrots, it also eats meat, and therefore could be New Zealand's answer to the smaller d...
252 million years ago, the worst event in the history of life on Earth occurred. 70% of all terrestrial species and 96% of all marine species became extinct through, according to geological record...
What is a flower or shrub back home is a tree in an alternate Earth, and vice versa. That is something worth exploring. For example, Taraxacum officinale can grow from stems typically up to 5...
Lately, there has been speculation of what would happen if all the untapped oil, by the handwaving powers of the gods of television and money, disappear overnight. It has been explained, in varyin...
As it turns out, conifers are not the only trees to grow in boreal forests, or taiga. At the southernmost ends, the evergreens are mixed with such deciduous trees as: Birch Alder Willow Poplar M...
A volcanic eruption is measured in two constants--gas and viscosity. For clearance, low viscosity is like squirting water off a nozzle, whereas high viscosity is like squirting caramel off a nozzl...
To clarify on the title, K-type main-sequence stars--shortened as "orange dwarves"--are subjects of excitement for astronomers and astrobiologists. Why? They emit enough radiation to provide a...
It turns out that a single strand of human hair measures 17 to 181 millionths of a meter wide. But anyone who creates or reinvents a fictional species of humanoid has the freedom to change the dim...
I'll confess that I have a real issue with iron--it rusts quickly. In fact, the History Channel program Life After People constantly states that, left to its own devices, the iron that makes up a ...
Let me clarify on the title, because this is important. In recent years, people have been feeling less comfortable calling the only natural satellite orbiting Earth a moon. It may not be the larg...
There seems to be a connection between orbital revolution (one year) and distance from the star the body orbits. For example, Earth orbits the sun at a distance of 93 million miles and completes o...
Believability of a fantasy creature can go so far. Case in point--the title feature. I have first seen it on a Ringwraith's winged mount... ...then on Smaug... ...and finally on the dragons...
In the History Channel program Clash of the Gods, some of the highlit characters have been given some interesting physical liberties. The episode "Minotaur" features King Minos with a meerkat-like...
Let me clarify on that title, because this question focuses specifically on vegetables that have not been cultivated for their fruits--like tomatoes, eggplants, peppers, cucumbers and pumpkins--or ...
Back home, the Tibetan Plateau averages 4,950 meters above sea level with its highest point being Mount Everest, 8,848 meters--29,029 feet--above sea level. At such heights, problems are resulted ...
In a hibernating speculative evolution project called The Speculative Dinosaur Project, the "speccers" feature a species of shark called Jasconius pelaganax, the Gigamouth, which is basically a meg...
It's common knowledge that the atmosphere of Venus is too inhospitable for a proper landing. The most concerning problem with that is pressure. Venus's atmospheric pressure is said to be 92 times...
