DNA, or deoxyribonucleic acid, determines whether our eyes are blue or brown, how tall we will be, and even our preference for certain types of behavior. We share around 60% of our DNA with bananas. 75 per cent of genes that cause diseases in humans are also found in the fruit fly. Bizarre mutations in fruit flies led to the discovery of genes that guide development. But what does this kind of statement really entail, and how do we really know how similar one creature’s DNA is to another?

How much DNA do we share with bananas? Once we start to think about the kind of world we are leaving to future generations, we look at things differently; we realize that the world is a gift which we have freely received and must share with others. When DNA and genes in different species look very similar, this is usually taken as evidence of them sharing ancestors. They are instructed not to eat the fruit of the latter tree, but they do so anyway and are subsequently cursed and expelled from the garden. We can no longer speak of sustainable development apart from intergenerational solidarity. It cannot become a special interest group debate. The common fruit fly, Drosophila melanogaster, is a well studied and highly tractable genetic model organism for understanding molecular mechanisms of human diseases.Many basic biological, physiological, and neurological properties are conserved between mammals and D. melanogaster, and nearly 75% of human disease-causing genes are believed to have a … Share on Pinterest The complete set of chromosomes in a human male. We also share a shocking amount of DNA with plants and insects. However, because we share many of the same essential needs to sustain life, such as the need for oxygen, these similarities are reflected in our genetics. A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors.
