Sharks are Misunderstood

Sharks are awesome creatures and are often misunderstood. 

I also feel misunderstood, so I got a shark tattoo on my arm.  However, that is not the point of this blog post, so let get back on track.

Here are some interesting facts about sharks.

  1. Sharks don’t have bones, instead they have cartilage.  That is what makes a shark a shark, it’s not about size, shape, or eating preferences.
  2. Sharks have electroreceptor organs and can sense electromagnetic fields.
  3. Shark skin is made of dermal denticles, which is so rough it could be used as sandpaper.
  4. The whale shark can grow up to 40 feet long, but lives on a diet of plankton.
  5. Bull sharks can live in salt and fresh water.
  6. The dwarf lantern shark is about the size of a goldfish.

The Biology of Belief

Dr Lipton explains how our environment, relationships, and belief system can actually change us on a biological level.

Here are a few interesting points made in the book.

  • Cells teach us about the mechanisms of life, and how to live rich, full lives.
  • Positive thoughts have a profound effect on behavior and genes, but only when they are in harmony with subconscious programming.  Negative thoughts have an equally powerful effect.
  • Single cells are capable of learning through environmental experiences and are able to create cellular memories, which they pass on to their offspring.

You don’t have to be a science major to understand and benefit from this book.  It’s easy to read and I found it to be uplifting.

What happened to the Neanderthals?

It was originally believed the Neanderthals were killed by humans that migrated out of Africa.  However, recent evidence from genetic studies prove humans and Neanderthals were interbreeding.

Researchers at National Geographic discovered, “the Neanderthal linage disappeared, because it was absorbed into the much larger human population.”  They found Neanderthal DNA in humans, especially in those with a strong European heritage.

Basically, the Neanderthals intermingled with humans until they were breed out of existence.

Opossums are Cool

I think opossums are cool animals and they are often judged to harshly.

Opossums are marsupials, which makes them a unique animal in North America.

They are omnivores and prefer to forge for food, so they make great clean up crews.

They have a powerful immune system.  They are even immune to snake venom.  You have to admit, that’s a seriously strong immune system.

They prefer a solitary lifestyle and are nocturnal, which makes them a bit introverted.  I’m an introvert too, so I can relate.

When a opossum is threatened it goes into a shock like state and actually faints.  This is an involuntary response, which kind of makes me feel sorry for the opossum.  If I fainted every time I got scared, that would be embarrassing.
