1. Methuselah is the oldest known tree

Methuselah is a bristlecone pine tree

From:  White Mountains of California

Age: A rough estimate of nearly 5,000 years

It is said to be the oldest non-clonal tree in the world.

The exact location of Methuselah is protected by the Forest Service.

2. The Giant Weta is the world’s largest insect!

The Giant Weta is the largest and heaviest insect as large as a small bird or mouse.


3. One Human DNA, if extended, reaches 10 Billion miles!

This is the equivalent of taking a trip to the sun from Earth 100 times or coming back from Pluto.

4. The human brain uses 20% of blood that our bodies produce.

A newer study in Proceedings of the National Academy of Sciences USA is finding that two thirds of the brain’s energy helps neurons or nerve cells “fire” or send signals.

The remaining third, is used for cell-health maintenance. 

 

Who helped with the project? Co-author Wei Chen: radiologist at the University of Minnesota Medical School. 

5. Our DNA, experiences damage in every cell 100 times a day.

Cool repair enzymes go up and down the helix repairing all the mistakes daily that detect the mistakes and repair automatically!

6. Tree rings do not accurately tell the age of a tree

Sometimes trees have false rings and also indistinct rings.

More than one ring may form in a given year.

M.S. Brian Thomas.

7. A rabbit can reverse it’s pregnancy!

During extreme fright or harsh winters, the stress sit not being able to find food causes what is called resorption.

In this process get body completely reabsorbs the growing embryo. This mechanism saves the mothers life so that she can have more babies when conditions are better.

The number of chemical and physical changes required for a rabbit to reverse a pregnancy is mind-boggling. There is no scientific evidence which explains how this remarkable resorption process could have evolved.

8. One large tree can pump 1000 gallons of water from the ground to it’s leaves.

That’s 4 tons of water! Or 8,000 pounds!

On a hot summer day

 

The water comes from the soul through the root system.

Often it must pump 100 feet high into the air!

Water is suctioned through 3 different mechanisms

1 Capillary flow

2 Osmosis

3 Vacuum pressure.

 

The leaves cause a pressure differential. Water evaporates from the leaves creating suction throughout the vessels of the tree.

 

If you cut one of these vessels you would actually hear a hiss of the air rushed back into these vessels; with the right equipment (not with normal hearing)

 

 

9. There are around 30 species of freshwater Pufferfish

There are around 120 different species of Pufferfish altogether.

10. The ears of an elephant can weigh about 100 pounds. 11. Humans have 639 independently controlled muscles. 12. Sound travels at 768 MPH 13. Jupiter’s three larger moons are named Io, Ganymede and Europa. 14. We have to have plants for balance and oxygen levels to live. 15. Leaves function like solar panels.

Leaves absorb the energy from the sun to the plant from the leaves.

16. A dinosaur was found with keratin on horns and raw flesh!

A nodosaur was found in Canada that weighed over 2,000 pounds paleontologist Jakob Vinther said it was like it was walking alive a week ago!

Ankylosaurus features so distinct with such a complete skeleton and skin! Found by a miner.

17. The common fly can zero in on a cricket by hearing.

The Ormia ochracea (common fly) zeroes in on the cricket because it lays it’s eggs on them.

The flies ears are connected to each other and scientists have yet to figure out how the fly can hear and discover the singing cricket.

18. The tallest living land animal is the giraffe.

The giraffe stands about 18 feet off of the ground.

19. The heart of a giraffe is about two foot long to support the blood flow in the ten foot neck! 20. The biggest problem for evolutionary processes is the sudden appearance if fully functional and formed body structures.

No transitional fossil has been found. (An in between evolved creature in the middle of becoming another kind of animal, plant, organism etc)

 

Darwin admitted this problem by saying it would be right to disregard his whole theory if no transitional fossil was found.

21. The human eye is wired backward.

The wiring faces toward the incoming light while the photoreceptors face the back of the retina. When light enters the eye and falls on the retina (back of the eye), it has to go through 10 layers to the very back of the retina for the photocells to be activated.

22. Photocells within our eyes are one of the most active areas in our bodies.

They need to be replenished every 7 days.

23. Only 2% of water is used for photosynthesis in trees. 24. There are over 9,000 species of birds. 25. The Giza pyramid was built with 115,000 casing stones.

These stones consist of polished marble

Weighing from 16-20 tons each!

The joint thickness was a miniscule 0.020 inch!

In the center the cement that was used to bong the stones was of greater strength than the marble itself.

The composition of sych cement is unknown to modern man or methods of today.

The largest blocks measured five feet high and 12 feet long and 8 feet deep with an average of 0.01 inch.

This amazing accuracy of exactness is very very difficult even with modern methods tiday.

 

We estimate that it would take about 100.000 men to construct a pyramid and would need to set a new block every 20 minutes to complete in 20 years.

 

There are over 2,000,000 quarried vlocks in the Grrat Pyramid.

26. The Praying Mantis have a hearing membrane in their thorax (chest area)

Scientists thought for a long time that they had no way of hearing.

 

Dr. David Yager discovered that mantids had this feature and demonstrated that flying mantids can detect the ultrasonic chirps of an approaching bat and advance and attack like a fighter her (pulling up into a stall position and turning sideways as it drops into a fast dive downward)

 

This aerial maneuver usually works to ward off the bat that wants a meal.

 

No other insect possesses the ultra sensitive ear that mantids do, nor are there evolutionary paths to this finished creature.

 

Fossil mantids even show the same features of hearing and they are actually placed in the fossil record before bats we’re to have evolved. 

Why would a mantids evolve something it didn’t need? Why doesn’t it show mantids actually evolving the feature?

Cool stuff. Full formed from fossils onward it makes more sense to believe it was originally designed and that bats existed alongside mantids all along.

27. Humans have around 50 facial muscles, half used for expressions.

Apes only have about 30 facial muscles of which none are used for facial expressions.

Humans are claimed to have been able to make 10,000 various expressions.

Humans have the most accurate ways of expressing emotion without a single word. Of which primates cannot do.

28. Warblers rest on the 7th day during migration!

Myles Willard, a high school science teacher, (also an award winning nature photographer, and bird watcher) documented this 18 years in a row and saw 1,500 individual warblers from over 20 species.

He graphed their migration habits and was very surprised that these birds have an instinct to work hard on the migration for six out of seven days and hold up for one day of rest.

There is no natural explanation for this behavior other than that it confirms the Biblical message to humans to “six days shalt thou labour and do all thy work” There truly is something to patterns in nature that humanity should heed.

29. Penguins have no teeth

How can they hold slippery fish in their mouths if they have no teeth?

Penguins have rearward-pointing, tooth-like barbs on the tongue and roof of their mouths that prevents the fish from sliding out of it’s mouth once caught.

They do not use these small barbs for chewing but rather gripping.

30. The elephant is the world’s heaviest land animal! Weight: Up to 6 short tons (5.4 t), The African elephant measures approximately 24 feet (7.3 m) 31. Scientists tell us that Bioluminescence has evolved at least 40 different times indenpendently.

How is it that bioluminescence evolved 40 separate times independently and is this really true science and have we proof for that?

Not really but if evolution is accurate and true, then different creatures possessing this ‘glowing’ feature would have had to evolve it 40 different times throughout evolutionary history! This is scientifically impossible!

32. The amount of oxygen in the air is 21%

If there were less then the animals would be breathless. If there was too much, fires would burn continually.

33. Carbon Dioxide is paramount for photosynthesis.

Plants convert the carbon dioxide into other carbon compounds.

34. Air acts like a screen preventing the sun’s harmful ultraviolet radiation

Air is a bit like a radiation screen.

35. Air causes the beauty of color in the sky

If we compare to the moon with no air it is a dark sky.

36. Air is odorless. Therefore we are able to smell the fragrances it blows to us from flowers etc.

Although there are difference fragrances air has no ‘scent’ that we can detect or bad smell like sulfur.

What a wonderful thing!

37. Humans can smell about 1 trillion odors!

Researchers laid claim that humans could only smell around 10,000 scents and odors, but neurobiologist Leslie Visshall of Rockefeller University said:

“People have been talked into this idea that humans are bad at detecting smells…So these findings should give the whole human race a confidence boost.”

She helped in the new research of this discovery.

Humans detect scents by breathing in the air that caries the odor molecules.

It’s amazing not only that the receptors inside the nose seems to tell the brain “Hey I smell popcorn” but that no matter how long it may be since we have sensed the scents, we always remember the smell with the object!

It is truly amazing.

Each smell is not simple with one or two odor molecules but many many to create the signature of coffee, chocolate, etc.

And the amazing thing is that we never mistake the smell of sulfur for the smell of apple pie!

38. The largest muscle in the human body is the brain.

Surprising that it is a muscle but it certainly is and just like we exercise our muscles our brain exercises through study.

39. There is no example nor observation of a ‘new star’ turning on or being born in the cosmos.

Surprising! I know! Many say they have spotted baby stars, or saw them in a ‘star’ nursery, but no new stars have been seen as they formed but have already been present when spotted.

There is no evidence to support the ‘baby’ new star turning on in the night sky.

 

 

40. In 2005, Dr. Mary Schweitzer found undecayed tissue, blood vessels, and cells within a fossilized T-Rex bone.

She said it “violates everything we know about the laws of chemistry and physics.”

What it really defied was evolutionary processes. And she didn’t want to go against evolution being the problem but rather the laws of science which we know can never be violated nor altered.

41. Deciduous Trees Means They Lose Their Leaves And Grow Them Each Year 42. Green Tea Fights Cavities

BOTANY: I didn’t know that green tea fights CAVITIES!! A chemical in GREEN TEA helps keep the chemicals that cause cavities from attaching to the surface of our teeth! One scientist, ISAO KUBO, discovered that certain molecules found in abundance in green tea actually KILL THE BACTERIA THAT CAUSES CAVITIES. His work also showed that green tea also helps fight 2 kinds of molds, 3 classes of yeast, and 8 kinds of bacteria! (AND A PARTRIDGE IN A PEAR TREE!!!) hahahahaa……..

And, green tea contains CATECHINS which also have so many health benefits, (helps our DNA, and digestion)!! .PRAISE GOD, THE CREATOR OF ALL PLANTS, ANIMALS, AND CREATION!!

43. Our ‘vestigial organs’ have use afterall. Anatomy: after Darwin proposed his “theory” in the late 1800’s, 180 organs in our bodies were considered useless junk. They were considered to be “left overs” from our evolutionary past…..The Appendix, & the gallbladder were considered useless. By the 1990s, Scientists have been very surprised that now, we have answers for every single organ in our body that they considered useless. Modern science, now knows that the appendix houses “spare” good bacteria. When we suffer with a stomach ailment, the bacteria from the “useless” appendix replace those that were lost. The gallbladder is a pear-shaped organ located just under the liver. The liver makes bile, which is stored in the gallbladder. The bile is used to breakdown fatty foods so they may be digested. Isn’t it amazing how our Designer/Creator God would design organs for our amazing bodies to be used in a wide variety of circumstances?? Praise God, Creator of all appendixes and gall bladders! 44. Non-vascular plants are moss, algae, lichen, and fungi

Non-vascular plants have no serious root structure, and no ability to take in water and store it or deliver it to the area of the plant that needs the water.

45. 369,000 species of plants (94%) are flowering plants. 46. There are about 100 trillion cells in the human body, each nucleus bears 46 chromosomes.
