A Horse is a Horse, Unless of Course it Isn’t a Horse


Quote:  “No one disputes that Mr. Ed really was a horse but what about the plains zebra, the quagga, or the donkey?  Too bad they can’t tell us.   Are these all horses (equines)? What about the other 15 extinct species, including the quagga, that are also called equines because they are assigned to the same genus?  What about the other 20 or more fossil genera and many more fossil species that have been named that are similar to the modern genus Equus that include the horse, donkey and zebra.  More to the point, when is a horse NOT a horse?   These are questions that drive scientists to critically examine how we define species and how we understand species to have formed over time.   I came across a story this past week about modern equine relationships based on complete mitochondrial genome sequences (for more on these genomes see:  Of Kinds and Common Ancestors: Comparing Mitochondrial Genomes of Animals) that got me to thinking about what makes a horse a horse.

About ExEB

I'm a agnostic/atheist . Interested in learning more about science. I also am an "ex-member" of a group most publicly known within modern times, as the Exclusive Brethren. Whom are an off-shoot of the original Plymouth Brethren group. I'd say it likely my personality could possibly be described as quirky.You know ,as in being , unconventional , unorthodox , unusual, off-centre, strange, bizarre, weird, peculiar, odd, freakish, outlandish, offbeat, out of the ordinary, bohemian, alternative, zany I'm sure iv'e been classed as "crazy" . Many times But then, being born into a group like the exclusive brethren. Doesn't lend itself ? to tend to produce things considered as being "very normal" .Does it I escaped the Exclusive Brethren cult as a 15 year old teenager. Even since that time iv'e been trying to adjust to living life outside the cult. With much of my life being lived within the genre of "wild colonial boy" style. In the general sense of a church-rebel picking and choosing from role models who appeared within-life along the way. But as the exclusive brethren cult had traditionally maintained a general church-rule , of need to shun and totally excommunicate any ex member of their group.Treating such people as if they were dead. Thus this situation developed more to do with my need of following traditionally enforced church-rule , as apposed to it being so much about "life-choices". Certain emotional experiences, and parts of life in general, have led to me adopting a sense of low self esteem. Which is a situation i still deal with from time to time. Through my ongoing interest in science. I find i am able to gather more information to help me better understand my situation. Much about life for me, has often seemed like a massive puzzle.With many missing pieces.
