Have you ever thought what actually is the very first animal on earth? Could it be the creepy crawly creatures and insects? Well if we take the bible as reference it says in Genesis 1:20, then we will learn that “There was evening and there was morning, a fourth day. Then God said,’Let the waters teem with swarms of living creatures'”
Surprisingly, science concurs with this!
When you think of “let the waters teem with swarms of living creatures”, what animal can you think of? Do you envision fishes only? Or maybe it is a plankton?
Nope, sorry the title of “first animal on earth” does not go to Plankton
While the planktons are a close candidate, due to their variability as a phytoplankton (plant planktons) and zooplanktons (animal planktons), they are not considered entirely to be “animals”. And thus, the title of the very first animal on Earth goes to a sea sponge called the “Comb Jelly”!

Previously, the comb jellies were thought to appear 450 million years ago. In retrospect, the dinosaurs are tagged to roam the earth at around 230 million years ago. However, a researched published by MIT biologists shared evidence that the comb jelly actually existed as far back as 650 million years ago! And the even more amazing feat is – the comb jelly is alive until today.

The evidence that the MIT biologists obtained were traces of a unique sea sponge biomarker, 24-isopropylcholestane detected in rocks under the sea. These were then dated to detect their time of appearance and thus the estimate of around 650 million years ago was formulated.
Due to this discovery, interest on the survival mechanism of these sea sponges are piqued. Imagine this multi-cellular animal even without organs, muscles and nerves, being able to live through 650 million years until today!
Now if we follow the evolutionary theory, did all humans, animals and all other life came from… a sea sponge? Amazing isn’t it?
Finland to Become First Country in the World to Get Rid of All School Subjects
Finland’s progressive teaching method takes on an integrated approach to learning, and it’s nothing like the method that’s been used for centuries.
For centuries, the formal educational system has been roughly the same. Topics are divided into subjects, and those subjects are taught independently of each other. There are subjects like Math, Science, Language, and Physical Education that are taught by different teachers at different times.
In Finland, a country known for its progressive views on teaching, this method of teaching will now replaced by a new and possibly more effective method. Finnish officials want to remove school subjects from their curriculum.
According to the head of the Department of Education in Helsinki, Marjo Kyllonen,
A Recent Study Explained Why Human Males Don’t Have A Penile Bone
Ever wondered why it’s all meat and no bone?
It is an established scientific fact that human males do not have the baculum, which is also known as the penis bone or penile bone. This anatomical truth has baffled people for years. Recently, however, a group of researchers from University College London decided to find out why human males are missing that one bone.
A study published recently in the journal 'Proceedings of the Royal Society B' explored the concept of baculum evolvement, along with the theory that humans lost it during the course of evolution as a result of monogamous sexual relationships.
The researchers propose that sometime between 95 to 145 million years ago, the penile bone evolved to provide mammals structural support during copulation and to allow them to have sexual intercourse for extended periods, as lasting longer in sex allows the animals to keep up with the increased sexual competition among male rivals. Hence, being able to last longer favors the males as it hinders other male animals from having sex with and impregnating their chosen female.
Virus Evolution May Cause More Severe Infections in Men than in Women
Men beware! The man flu is real!
Men may be more predisposed to more severe infections as compared to women.
In a recent study published in the journal Nature Communications, it was found that pathogens tend to evolve in a sex-specific pattern, thus causing weaker symptoms in women and making them more likely to spread the infection. This means that such microorganisms may be evolving in such a way that will allow it to cause more serious infections in men than in women.
The theory suggests that it is possible for viruses to infect a woman, but not necessarily cause them significant harm, as there is a greater likelihood for women to transmit the infection to others, that is from a mother to a child, either through breastfeeding or giving birth. Men, on the other hand, are not involved in vertical transmission, hence there is a lesser likelihood of transmitting infections to others. This means that viruses can let it all out and wreak havoc on a male host's system, thus causing more severe symptoms.
