Will humans ever be able to fly with wings?
Sadly, science is against this dream. According an article in Yale Scientific, “it is mathematically impossible for humans to fly like birds.” For one, the wings — both span and strength — are in balance with a bird's body size.
Did humans ever fly?
For many centuries, humans have tried to fly just like the birds. Wings made of feathers or light weight wood have been attached to arms to test their ability to fly. The results were often disastrous as the muscles of the human arms are not like a birds and can not move with the strength of a bird.
Can humans be immortal?
Cryonics holds out the hope that the dead can be revived in the future, following sufficient medical advancements. While, as shown with creatures such as hydra and Planarian worms, it is indeed possible for a creature to be biologically immortal, it is not known if it will be possible for humans in the near-future.

It would be similar to having a finger broken. Tails would be sexualized. Tail length and girth would become a major factor in how males were perceived and “tail envy” would be ubiquitous. There would be fierce, violent debate over whether it is proper for females to expose their tails in public.

How long will the earth last?
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.
Will humans go extinct?
Scientists estimate modern humans have been around about 200,000 years, so that should give us at least another 800,000 years. Other scientists believe we could be here another two million years…or even millions of years longer. On the other hand, some scientists believe we could be gone in the next 100 years.
What if humans had gills?
In short, the presence of gills would lead to speciation into aquatic and terrestrial humans. Alternately, if the terrestrial humans weren't as well suited to life on land as the neanderthals were, humans would stick to coastal regions and neanderthals would be the dominant terrestrial hominid.
Did humans have gills?
As it happens, early human embryos do have slits in their necks that look like gills. This is almost certainly because humans and fish share some DNA and a common ancestor, not because we go though a “fish stage” when in our mothers' wombs as part of our development towards biological perfection.
Can cats fly?
Carry-On Pets Small dogs, cats and household birds can travel in the cabin for a one-way fee, collected at check-in. They must be able to fit in a small, ventilated pet carrier that fits under the seat in front of you.

Can a fish survive in milk?
Fish have evolved over many millions of years to survive in water with a certain amount of dissolved oxygen, acidity, and other trace molecules. So, though skim milk is nine-tenths water, it still would be entirely insufficient to support a fish for long.

Human tails are a rare entity. The birth of a baby with a tail can cause tremendous psychological disturbance to the parents. They are usually classified as true and pseudo tails. (1) Tails are usually associated with occult spinal dysraphism.
Do we hiccup because we used to be fish?
Our brain stems, inherited from amphibian ancestors, still spurt out odd signals producing hiccups that are, according to Shubin, essentially the same phenomenon as gill breathing. This is atavism, or evolutionary throwback activity, at work.
What if my cat meows on a plane?
Pet your cat through the carrier. If he falls asleep, don't disturb him. Offering one or two treats or a finger wet with water can help calm your cat down during the flight, according to PetTravel.com.

By 2050, about 75% of the world population will be living in cities. Then there will be buildings touching the sky and cities will be settled from the ground up. Roads will be built up to several floors. And to move around, the buildings will be connected to the skywalk.
Can a fish get drunk?
That's right—fish get drunk, too! Working with Zebrafish—a common fish used in lab studies—researchers at NYU exposed fish to various environments of EtOH, technical-speak for alcohol.
Can a fish drown?
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don't technically drown, because they don't inhale the water, but they do die from a lack of oxygen. Fishing equipment, such as some types of hooks, can damage the gills.
