Bowler, Peter J. Both Wallace and Darwin saw the history of life like a family treewith each fork in the tree's limbs being a common ancestor. Charles Darwin simply brought something new to the old philosophy -- a plausible mechanism called "natural selection. Because of the morphological similarities present in embryos of different species during development, it was once assumed that organisms re-enact their evolutionary history as an embryo. Philosophie Zoologique. A common example of a population bottleneck is the Northern elephant seal.

The instructions spelled out by this DNA alphabet can be changed, however, by mutations, and this may alter the instructions carried within the genes.

    In this case, closely related species may regularly interbreed, but hybrids will be selected against and the species will remain distinct.
