Evolution Test Day

We started by addressing some mistakes in how people were thinking about isolating mechanisms between species.  A reminder that these are ways in which successful reproduction is PREVENTED between members of different species.

I then gave the Evolution Test.  It is 28 multiple-choice questions.  If you were absent you must see me to schedule to take this test as soon as you return to school!

I also distributed a list of vocabulary prefixes, suffixes and root words.  Each TUESDAY you will be given a quiz on scientific terms containing words from this list.  The quizzes are 20 matching questions.  The first quiz will be next Tuesday, March 22nd.  In case you have misplaced your list, I have included it below.

PREFIXES, SUFFIXES, AND STEMS

The following list gives the meaning of prefixes, suffixes, and stem that are commonly used to form scientific terms. Whenever you encounter a new term in your study of biology, break it apart and try to find the parts in this list. Such a habit will greatly simplify your mastery of biological vocabulary.

As an example, you might take the word nephrology. The stem nephro‑ is derived from the Greek word nephros, meaning kidney, while the stem log‑ is derived from the Greek word Logos, meaning thought or study of. You might later encounter the word nephrolith, and you would then only have to determine the meaning of the suffix ‑lith since you would already know the meaning of the first part of the word. Or when you ran across such words as bacteriology and zoology, you would probable have a good idea of what they mean. After some practice, you will be surprised how many new words you can define without looking them up.

It has often been necessary to add a vowel to combining forms for pleasing pronunciation. For example, bacteri‑ + ‑logy becomes bacteriology. For the same reason it has been necessary, at times, to drop or change a vowel in a prefix, suffix, or stem. For example, gastro‑ becomes gastric, the adjective pertaining to the stomach.

Most scientific terms are derived from either the ancient Greek or the Latin because neither of these languages is in used now so that they are unchanging, and also they are studied universally. As a result, you will find that Latin noun endings are often used in biology. As a help in determining the plural of words with Latin endings, you might memorize the following:
