The principal aim of life history theory, a branch of evolutionary ecology, is to explain the remarkable diversity in life histories among species. But there is another, more compelling reason for why life history evolution is important: adaptation by natural selection is based on variation in Dar...
Beginning with its roots in conventional breeding and working right up to the cutting edge fields of optogenetics, gene editing, and synthetic biology, the book is accessible to those with some undergraduate-level genetics, or secondary school biology and a keen interest in the subject. This audie...

Evolution, theory in biology postulating that the various types of living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations. The theory of evolution is

Examples of Natural Selection Darwin’s Finches are an example of natural selection in action. They are an excellent example of the way species’ gene pools have adapted in order for long term survival via their offspring. See this tutorial for more elaborate info on natural selection as exempli...
The meaning of EVOLUTION is descent with modification from preexisting species : cumulative inherited change in a population of organisms through time leading to the appearance of new forms : the process by which new species or populations of living thin
We use this isomorphic lesson and a pre-post study design administered in a split-section introductory biology classroom to isolate the importance of the species context. Results For two of the four measurements of interest, the effect of using human examples could not be understood without ...
[145,146]. The evolution of novel functions and pathways can be hardly observed in a laboratory evolution experiment, even with microbial cells and their fast growth rates. Nevertheless, there are a few examples that highlight that a novel trait can emerge rapidly on a laboratory time scale. ...
