Transgenerational Plasticity Is Sex-Dependent And Persistent In Yellow Moneyflower (Mimulus Guttatus), Kayla Akkerman
Transgenerational Plasticity Is Sex-Dependent And Persistent In Yellow Moneyflower (Mimulus Guttatus), Kayla Akkerman
All Master's Theses
Transgenerational phenotypic plasticity, whereby environmental cues experienced by parents alter the phenotype of their progeny, has now been documented in diverse organisms. Transmission of environmentally determined responses is known to occur through both maternal and paternal gametes, but the underlying mechanisms have rarely been compared. In addition, the persistence of induction over multiple generations appears to vary widely but has been characterized for relatively few systems. Yellow monkeyflower (Mimulus guttatus) is known to exhibit transgenerational induction of increased glandular trichome production in response to simulated insect damage. Here we test for differences between maternal and paternal transmission of …
Some Interactions In The Evolution Of Man And Tools, Gary W. Weston
Some Interactions In The Evolution Of Man And Tools, Gary W. Weston
All Master's Theses
This paper looks at some of the interactions between the development of tools and the evolution of man and his ancestors. It begins with a brief history of life up to the primates as a foundation. Next the use of tools by other animals is examined followed by the coverage of the period of time from Australopithecus to Modern Man showing the interweaving of physical and mental evolution of man and the development and refinement in his physical tools. Lastly, a look at possible future interactions in the physical and mental evolutionary developments in man as influenced by his tools …
