Evidence From Botany – January 4
On a hot summer day, one large tree can pump over a thousand gallons—that’s four ton—of water from the ground to it leaves. The water is collected from the soil through the roots. But the real work of pumping four tons of water, often 100 feet in the air, occurs at the top of the tree. The water is suctioned toward the treetop by three remarkably efficient mechanisms—capillary flow, osmosis and vacuum pressure. Osmosis and capillary action act in concert to move the water partway to the top of the tree, but the real driving force is a pressure differential created by the leaves within the vessels of the tree. The pressure differential is a result of water evaporating from the leaves of the tree, creating a suction throughout the vessels. This suction (measured as low as 1/20 of atmospheric pressure) helps to draw water from the roots all the way to the top of the tree. If you were to cut one of these vessels, you could actually hear a hissing sound as air rushed back in.

The engineering excellence of this silent pumping system which efficiently delivers moisture to the very top of trees, is a not-so-silent witness against the idea that chance evolutionary processes (such as mutations) could have developed it.
Do you not know? Have you not heard? The LORD is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and His understanding no one can fathom. Isaiah 40:28

Evidence From Botany – August 16
The skunk cabbage is a uniquely designed plant. It generates enough heat to melt the snow around itself so that it can begin to grow and flower. Even if the air temperature drops as low as 10oF, the skunk cabbage produces the heat it needs to maintain a temperature of between 72°F and 74°F. However, if the temperature stays extremely low for more than 24 hours, the hooded blower exhausts its heating ability and the flower dies. The skunk cabbage then prepares more flowers and repeats the process.
Western Skunk Cabbage from Wikipedia
This amazing plant also has a built-in thermostat. If the flower becomes too cold more heat is summoned. If the flower becomes too warm, the heat is withdrawn. Because of its amazing abilities, the skunk cabbage is one of the first plants to break through the snow in early spring. Normally, honeybees are unable to fly in temperatures below 65°F. However, when the skunk cabbages are in bloom, honeybees can fly when temperatures drop as low as 45°F. Inside the flower’s hood, the bees warm up enough to travel to the next cabbage flower. In cold weather the bees fly from one skunk cabbage to another, warming themselves as they travel back to their hive. Could this intricately designed flower be the result of random-chance mutational changes?

I will ponder all your work, and meditate on your mighty deeds. Your way, O God, is holy. What god is great like our God? (Psalms 77:12-13 ESV)
