Why do humans have earlobes ??

 WE DON'T KNOW THE REASON    !!!!

Earlobes are one of those body parts that don't have a single, obvious job  !!!

Earlobes vary a lot across people. 

Other primates have much smaller or no distinct lobes.

Removing them surgically won't affect hearing or to maintain balance.

Earlobes are made up of skin and fat, no cartilage or muscle. They are just structural left overs.

Some theory states that earlobes might help dissipate heat since they are fatty and have a good blood supply.

There is no bones in earlobes so it doesn't affect hearing.

But researchers  say earlobes are an evolutionary byproduct with no critical function  !!!!

What does herding the cat mean ??

  Herding cats is an idiom used to describe a task that is extremely difficult, chaotic and nearly impossible to manage.

It refers to the challenge of trying to organise or control a group of  individuals who are uncooperative.

We can keep a cow or sheep together. They naturally stay together in a herd.

But not cats   !!!!

Cats are solitary and headstrong.

If we try to push them in one direction, they are likely to scatter around or hide.

Or they just simply ignore us    !!!!

To describe an impossible task to do ,  this idiom is used.

Why Titan is weird ??

 Titan is Saturn's biggest moon. 

Titan is weird because it is the only world besides Earth, with stable liquids on surface, an Earth like cycle and complex organic chemistry.

Everything is made up of ice and gasoline instead of water  !!!

Titan has rivers, lakes and seas.  But not of water !!!

They are made of liquid methane and ethane.

Rain falls, cloud forms and there are seasonal storms too. Titan is the only place besides Earth with full weather cycle !!!

Titan has dense atmosphere. Atmosphere mainly comprised of Nitrogen just like Earth  !!!

Titan is Earth like, but super cool. Cold enough that water ice is as hard as rock  !!!
