Fire Ants Fire ants have been in the United States for over sixty years‚ and almost every American that lives in or frequently visits the quarantined states which they inhabit has had an unpleasant run in with these troublesome critters. Inhabitants of the Southeast who have ever stood unwittingly atop a fire ant mound know that the insects are aptly named. When the ants sting it creates a sensation similar to scorching caused by a hot needle touching the skin momentarily (1. Tschinkel 474)

The juvenile individual from Jebel Irhoud (Irhoud 3) is represented by a well preserved mandible that dates from just less than the geological ages of the earliest evidence for early H. sapiens in East Africa (Smith‚ M.

C.elegans Research Project Madison Wall A. C. elegans is an ideal organism to use for studying aging because it is generally small in size and has a rapid lifespan. (http://cmgm.stanford.edu/~kimlab/index_wormaging.html). The organism also shares many essential biological characteristics that cause problems in human biology.(Edgley 2014). Worms can be genetically mutated fairly easily because of their 4-day generation time‚ where it develops from an egg to an adult with a maximum length of 1.5mm

It was no longer man the hunter‚ but man the hunted. In the cave‚ there were dismembered parts of large mammals which were within range of the prey size of many large extant African birds of prey. The mandible was still intact and the skulls were not completely crushed. These features are consistent with the behaviours of birds of prey such as the Black‚ Martial‚ and Crown eagle. Typically‚ hyenas‚ leopards and other mammalian carnivores crush skulls and

of consonants‚ excess and equal stress‚ and irregular articulatory breakdowns. (pg 164) The errors concerned with apraxia are articulation errors‚ limited prosody‚ slowed rate of speech‚ and visible groping behaviors- where the tongue‚ lips‚ and mandible work to find the appropriate positioning needed to effectively produce words. (Pg 133). There are various other deviant speech characteristics that may potentially be present in ataxic dysarthria‚ some of which coincide with characteristics of Apraxia
