Yes, everyone's, even yours, is amazing! I thought that the basic sciences, particularly first semester, would be very boring. However, even though learning it is a ton of work and not always the first thing I want to do, it is extremely interesting. I think everyone knows that the human body is really pretty incredible, but most people probably have no idea of the extent. I certainly do not have the time (or the knowledge, yet), to get into everything that our body must do all the time to keep us alive and healthy, but it's extraordinary. Just as a small example...the DNA in every single cell of our body is actually 2 meters long if you were to stretch it out. However, it is compacted in such a way that it can fit into a small part of a microscopic cell. Despite being so compacted, there are a ton of enzymes, proteins, steroids, and other various things which all work as tiny little machines to unwind this structure, piece by piece, duplicate it, and make functional proteins off of it. And even more tiny machines are involved in deciding just when and where your DNA should be transcribed. And they do it FAST! They rarely make mistakes, but when they do, they can even proofread and fix them, on the fly! Of course, various failures of these mechanisms are causes of tons of diseases. Just in the little over a month I've been here, I've learned enough that I could easily spend all day convincing you how nearly impossible it is to imagine that we came to be. Fortunately, we have had billions and billions of years to evolve to the point that we are at now.
On that note...the block exam is looming nearby, so I should get back to studying! Today will mostly be devoted to molecular and cellular bio (MCB) and histology, with probably a little anatomy thrown in for good measure.

I can't wait to speak to you about how the body works. I don't want to take your time from studying now but I look forward to speaking with you later. GOOD LUCK on your exams.
I know you will do well,
Your biggest fan
well since we havent been around for billions and billions of years this sounds like a pretty good argument for intelligent design.
There is not a single valid argument for intelligent design. There is no question, life certainly did not come to be by intelligent design. Actually, as amazing as human life is, it is far from perfect. Any god that would make so many mistakes doesn't impress me much.
Let me clarify...life has been around for billions of years (about 4 billion). This is not my opinion, but fact. To say that the earth is only a few thousand years old is absolutely false and ridiculous. The reason people don't understand evolution though is because it is excruciatingly slow. If it were true (which it is certainly not) that the earth was only a few thousand years old, it would not be possible. However, the time from the emergence of life on earth to the first organisms with cellular walls was about 100 million years, meaning billions of generations of trial and error. The first rudimentary animals arrived about 600 million years ago.
Evidence for evolution is everywhere in the DNA. There are sequences in our DNA (some of the most important) that we share with single celled life, that have remained the same through millions of years. We can compare our DNA to our ancestral DNA and see similarities all over the place.
For anyone to believe that we did not evolve, that we were jut put here on earth by some [not terribly intelligent] god, shows both a gross lack of education and reason.
Reading your blogs is like being a "fly on the wall". You are a very fine writer, strong and clear.
Your photography is outstanding!
