Alfred Russel Wallace Notes 28. Wallace's 'Change Of Mind', Revisited, Charles H. Smith
Alfred Russel Wallace Notes 28. Wallace's 'Change Of Mind', Revisited, Charles H. Smith
Faculty/Staff Personal Papers
Alfred Russel Wallace (1823−1913) is best known for his work on the theory of evolution by natural selection, and studies on biogeography. This fame has not, however, prevented appraisals of his work that sometimes depart from rational interpretations of his actual words. In this study, the frequently-offered notion that his adoption of spiritualism in late 1866 caused him to reverse himself on the universality of natural selection is taken to task, with arguments linked to his own words on the subject.

Faculty/Staff Personal Papers
The year 1866 was the first year Alfred Russel Wallace showed definite signs of breaking with Darwin over the limits of natural selection. Attention is drawn to a July 1866 exchange of letters between the two, and how this foreshadowed what followed.

Alfred Russel Wallace is well-known for his co-discovery of the principle of natural selection. Natural selection is usually considered a process, but it is not clear that Wallace regarded it in exactly these terms. In fact he more likely thought of the relationships involved as representing what we would now term a “state space,” a negative feedback loop wherein populations are maintained at healthy levels through elimination of the unfit. Both before and after the advent of natural selection Wallace clung to the idea that “more recondite forces” were shaping the nature and direction of evolution; this is especially evident …

Factors Influencing Predation On Juvenile Ungulates And Natural Selection Implications, S. M. Barber-Meyer, L. D. Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Juvenile ungulates are generally more vulnerable to predation than are adult ungulates other than senescent individuals, not only because of their relative youth, fragility, and inexperience, but also because of congenital factors. Linnell et al.’s (Wildl. Biol. 1: 209-223) extensive review of predation on juvenile ungulates concluded that research was needed to determine the predisposition of these juveniles to predation. Since then, various characteristics that potentially predispose juvenile ungulates have emerged including blood characteristics, morphometric and other condition factors, and other factors such as birth period, the mother’s experience, and spatial and habitat aspects. To the extent that any of …
