The Four Criteria For Life

Posted by on March 15, 2011

So I’m doing biology.  It could certainly be more interesting.  But hey!  I could be doing chemistry, right?  So I’ve started my Apologia text book so very many times and every time I get a few modules into it, something happens that I have to take a bit of time off of it, and then when I get back to it I have forgotten every bit!!  So I start over.  It’s not funny.  Really, it’s not.  So here is my next effort- I’m gonna read about “biological stuff” and blog about what I’m learning.  Hopefully that will keep me on track.

Let’s start with the basics.  What are the criteria for life?

To be considered alive, there are four criteria for an object to meet.

1.  All life forms must contain Deoxyribonucleic Acid (commonly called DNA).

2. All life forms must have means of extracting energy from their surroundings and converting that into energy that sustains said life form.

3. All life forms must be able to sense changes in their surroundings and respond appropriately to those changes.

4. All life forms must be able to reproduce.

Simple enough, right?  I think that is a list that both Creationists and Evolutionists can agree on (I am staunchly of the former category).

I’m using the internet and Biology for Dummies (I have no problem placing myself in that category in this subject) until I get home next month where my text book is.  So if I get my information screwed up or wrong or if I make grammatical or scientific mistakes, please forgive me and tell me how I can improve my information.
