Lisa Rose, with the twenty first century understanding of the whole DNA coding within the human genome, it is recognised that we share about 50% of our genes... the bits which determine what living things are ...with herbaceous plants such as bananas, delphiniums and strawberries. (That’s why I use the name Half banana)
What it tells us is that each animal, plant, fish or fungus is not a distinct creation but are variations on a slowly unravelling line of inheritance, a part of a continuum. The degree of difference between species determines their closeness or distance of relatedness. So the strawberry for example shares the same family traits as the rose but is not so closely related to the delphinium so they have different ‘recent’ ancestors. Apes share something like 96 to 98.5% of their genes with humans. The pattern is compared to a family tree or pedigree with new families branching off at intervals over time.
Perhaps surprisingly, most family lines that have ever existed have died off and become extinct leaving only those alive today most suited to their environments. These developments having taken place over literally millions of years. Life in all its many forms has proved to be a death and destruction derby where only the winners get to breed.
In essence the fact that we share 50% of our genes with bananas and strawberries means that Darwin’s idea that life has evolved; is the truthful account of the reason for our existence.
