Several studies have been conducted on human memory and on subjects' propensity to remember erroneously events and details that did not occur. Elizabeth Loftus performed experiments in the mid-seventies demonstrating the effect of a third party's introducing false facts into memory.4 Subjects were shown a slide of a car at an intersection with either a yield sign or a stop sign. Experimenters asked participants questions, falsely introducing the term "stop sign" into the question instead of referring to the yield sign participants had actually seen. Similarly, experimenters falsely substituted the term "yield sign" in questions directed to participants who had actually seen the stop sign slide. The results indicated that subjects remembered seeing the false image. In the initial part of the experiment, subjects also viewed a slide showing a car accident. Some subjects were later asked how fast the cars were traveling when they "hit" each other, others were asked how fast the cars were traveling when they "smashed" into each other. Those subjects questioned using the word "smashed" were more likely to report having seen broken glass in the original slide. The introduction of false cues altered participants' memories.
The reason why the Coyote brush has such large root system is the dry climate in the chaparral. By having large root system the plant is able to get moisture from places that are further away from the plant itself.
If the Coyote brush finds itself in an area where the climate is much wetter, with higher levels of moisture, than it will certainly undergo so changes to adapt to the environment. The biggest probability is that the plant will have smaller root system, but be able to grow more. The reason for that will be that the higher amounts of moisture will enable the plant to get enough water without any problem, so a very large root system will not be needed. Also, because of the higher amounts of moisture the plant will be able to grow bigger as it will not have to restrict itself because of lack of water and nutrients.
