Natural selection trends
WebConclusions. Many ecologists primarily interested in population dynamics have been sceptical of the relevance of genetics and natural selection in their research. Historically, this view stems from the belief that selection is invariably density dependent or soft, with negligible reciprocal effects on density itself. WebDarwin's seminal book, On the Origin of Species, set forth his ideas about evolution and natural selection.These ideas were largely based on direct observations from Darwin's …
