Evolution is a puzzle from the past that is yet to be solved. Its about the changing of organisms on earth from period to period. Questions are asked like ‘do all organisms evolve’ and ‘what are the missing links’. But the question that I’ve always thought about: ‘is evolution still happening right now’. And the answer is yes.
The platypus is among nature’s most unlikely animals. In fact, the first scientists to examine a specimen believed they were the victims of a hoax. The animal is best described as a combination of more familiar species: the duck (bill and webbed feet), beaver (tail), and otter (body and fur).
Males are also venomous. They have sharp stingers on the heels of their rear feet and can use them to deliver a strong toxic blow to any foe.
Females seal themselves inside one of the burrow’s chambers to lay their eggs. A mother typically produces one or two eggs and keeps them warm by holding them between her body and her tail. The eggs hatch in about ten days, but platypus infants are the size of lima beans and totally helpless. Females nurse their young for three to four months until the babies can swim on their own.
Platypus is a combination of species like a duck, otter and a beaver. It has a beak and webbed feet just like the duck and tail from the beaver and body and fur from the otter; but it has toxic poison as a self defense mechanism that the three species, the duck, otter and beaver doesn’t have and its eggs would hatch for just about 10 days. Platypus is one of the most unlikely animals.
Biologists and dolphins have created a new inter-species language
Biologist Denise Herzing has been studying wild spotted dolphins for years in the Bahamas. Like many people who research dolphins, she’s heard the animals communicating with each other but hasn’t figured out how to understand what they’re saying. And yet dolphins have learned our languages: Many studies have shown that dolphins can understand human vocabulary and syntax. The problem is that dolphins can’t respond in kind: They simply aren’t able to make the sounds required to speak our languages. Herzing wanted to change that. So she set out to construct a shared language with dolphins, using a synthesizer to create a vocabulary both species could pronounce. And it worked better than she’d ever hoped.
According to Wired:
Herzing created an open-ended framework for communication, using sounds, symbols and props to interact with the dolphins. The goal was to create a shared, primitive language that would allow dolphins and humans to ask for props, such as balls or scarves.
Divers demonstrated the system by pressing keys on a large submerged keyboard. Other humans would throw them the corresponding prop. In addition to being labeled with a symbol, each key was paired with a whistle that dolphins could mimic. A dolphin could ask for a toy either by pushing the key with her nose, or whistling … Herzing’s team found that six dolphins, all young females, were interested in the game, and would come to play when the game was on …
So now Herzing and the dolphins are able to ask each other for specific objects. Our two species have a shared vocabulary. It’s actually a little weird that nobody thought to do this with dolphins before, given that scientists have used sign language to hold conversations with chimps and gorillas.
Herzing says her study has implications for communicating with extraterrestrials. Far more intriguingly, it means that we are able to have two-way conversations with dolphins for the first time. Biologists just need to construct a more complicated human-dolphin language so that we can talk about things other than balls and scarves. What are the cetaceans going to tell us when we finally understand them?
Although horseshoe crabs have remained relatively unchanged for over 250 million years this living fossil of a creature now provides modern science with a substance crucial for saving thousands of lives. This is the miracle blue blood of the horseshoe crabs. Unlike the red blood of other animals which contains iron, the horseshoe crab’s blood has copper in it which is what makes their blood blue in color. But it is not the color of the horseshoe crab’s blood that makes it remarkable. It is the fact that this blood will quickly clot when it comes into contact with even the minutest impurities.
Their blood contains amebocytes, which play a role similar to white blood cells for vertebrates in defending the organism against pathogens. Amebocytes from the blood of the crasb are used to make Limulus amebocyte lysate or LAL, which is used for the detection of bacterial endotoxins. This is what makes the horseshoe crab’s blood truly miraculous since it is the only substance known which can so effectively detect impurities.
Despite the fact that the horseshoe crab’s blood is so vital to medical science, much of the horseshoe crab’s population is being depleted due to over-harvesting. Fishermen have found that horseshoe crabs make excellent bait for conch and eels. Most of the horseshoe crabs are found in the North Atlantic, with the bulk of them in the Delaware Bay area. As a result, states in that region have reduced by 25 percent the numbers of horseshoe crabs that can be harvested. As to the horseshoe crabs that are used for medical purposes, needles are used to draw their blood out of them. When approximately one-third of their blood is withdrawn, the horseshoe crabs are returned to the water. They will then survive to perhaps one day supply yet more of their precious blue blood to medine.
Liquid water may survive on free-floating planets that have no star to warm them. If they also support life, they could act as stepping stones to spread life around the galaxy. Gravitational tussles with other planets or passing stars can eject planets from their solar systems. But even in the cold of space, these wayward worlds could stay warm, thanks to the decay of radioactive elements in their rocky cores.
In 2007, South Korean scientists altered a cat’s DNA to make it glow in the dark and then took that DNA and cloned other cats from it creating a set of fluffy, fluorescent felines.
Here is how they did it: The researchers took skin cells from Turkish Angora female cats and used a virus to insert genetic instructions for making red fluorescent protein. Then they put the gene-altered nuclei into the eggs for cloning, and the cloned embryos were implanted back into the donor cats making the cats the surrogate mothers for their own clones.
What is the point of creating a pet that doubles as a nightlight? Scientists say the ability to engineer animals with fluorescent proteins will enable them to artificially create animals with human genetic diseases.

Electricity from potatoes? Wow! With just some potatoes, zinc and copper, you can have a home made battery! Imagine that! And guess what, you can even make it more powerful! Scientists say that boiled potatoes are 10 times more powerful than a raw one.
I didn’t know that!
- Rabbits and parrots can see behind themselves without even moving their heads!
- Butterflies taste food by standing on top of it! Their taste receptors are in their feet unlike humans who have most on their tongue.
- Most of the dust in your home is actually dead skin! Yuck!
- Although the Stegosaurus dinosaur was over 9 metres long, its brain was only the size of a walnut.
- Humans get a little taller in space because there is no gravity pulling down on them.
- Because of the unusual shape of their legs, kangaroos and emus struggle to walk backwards.
- A hippopotamus may seem huge but it can still run faster than a man.
- Even if an analog clock is broken, at least it shows the correct time twice a day.
- Sneezing with your eyes open is impossible.
- The trickiest tongue twister in the English language is apparently “Sixth sick sheik’s sixth sheep’s sick”. Give it a try and see for yourself.
