Jargon used in Issues in Evolution Readings[]

I'm just going to admit it I have no clue...[]

It turns out that either the evolutionary ecology class I took was not the great or it has been so long that new developments have changed the way it was taught, regardless of the reason, when I first started doing research for this class. I had no clue what was being discussed. So, I decided to make a list of the words that I had to look up. Hopefully, this will help future students understand the reading more quickly than I did.

Jargon Defined []

These words may not be "science" words, but, lack of my knowledge of their definitions truly slowed the learning process for me. Autochthnous (Merriam-Webster.com) - indigenous, native; formed or originating in the place where found  Consanguinity (Concise Encyclopedia) Kinship characterized by the sharing of common ancestors (derived from the Latin consanguineous, meaning “of common blood”). Kin are of two basic kinds: consanguineous (sharing common ancestors) and affinal (related by marriage). Today consanguinity is a genetic concept that influences the probabilities of specific combinations of characteristics, called genotypes. The probability that two consanguineous individuals will share the same traits depends upon the mode of inheritance (dominant or recessive) and the degree of penetrance or expressivity of the causative gene. Higher rates of mortality and rare diseases and disorders are more common in the offspring of consanguineous unions. While consanguineous marriages of various degrees have been practiced, all societies have incest taboos prohibiting marriage or sexual relations between certain kin.  M.a. time scale- means millions of years from the present; a term geologists use

Extant- (Merriam-Webster.com)-still in existence

Orthograde clambering behavior-(Journal of Anatomy)  – walking with the body upright in an awkward way (Orangutans do this)

Parsimony (UCMP Glossary) - Refers to a rule used to choose among possible cladograms, which states that the cladogram implying the least number of changes in character states is the best.

Microevolution(Evolution 101) "is evolution on a small scale — within a single population. That means narrowing our focus to one branch of the tree of life."

Macroevolution (Evolution 101)-"is evolution on a grand scale — what we see when we look at the over-arching history of life: stability, change, lineages arising, and extinction."

Also, for all your basics on Evolution, check out this website. It is great and truly explains the basics in an easy to understand way. I used it numerous times during "Issues in Evolution"
