"......From this advantageous position, the winning plant has a better ability to spread seeds and reproduce, which gives the species an even bigger footprint in the next generation. This process gets repeated again and again until the plants that are slightly better than the competition dominate the entire forest.
Scientists refer to this effect as “accumulative advantage.” What
begins as a small advantage gets bigger over time. One plant only needs a
slight edge in the beginning to crowd out the competition and take over
the entire forest......
Something similar happens in our lives.
Like plants in the rainforest, humans are often competing for the
same resources. Politicians compete for the same votes. Authors compete
for the same spot at the top of the best-seller list. Athletes compete
for the same gold medal. Companies compete for the same potential
client. Television shows compete for the same hour of your attention....."
