Those stats are about the 1% to 2% not the 98%. Our DNA with all life is mostly the same. The differences between looks in those stats you talk about are the face cards that make each card look different. The back of the DECK of cards is still the same for all life.
Yes we are talking about the coding sequences of DNA not the so called junk portion. So technically it is incorrect to say we share 60% of our DNA with a banana. After that though I think you have it wrong. For example the human genome has about 3 billion base pairs. Paris japonica, a rare flower found in Japan, has the largest genome known with about 149 billion base pairs. The smallest known genome belongs to the parasite Encephalitozoon intestinalis with only 2.25 million base pairs. The Paris japonica genome is about 50 times larger than the human genome. The human genome is about 13 times larger than the Encephalitozoon intestinalis genome. The Paris japonica genome is about 660 times larger than the Encephalitozoon intestinalis genome. That being said it kind of makes it hard to say that the genomes of all known life are mostly the same.
I get what you are saying.
Laypeople should not think of a strand of DNA as always being the same size. Just like you can buy different size rubber bands at Staples. My point is the base is the same, no matter how many links get added or subtracted to make the species DNA strand smaller or larger over time.
Yes, just like a shirt size, you have boys small, large and extra large. You have girls size small, large and extra large. And you also have adult men's small, large and extra large. You also have adult female small, large and extra large.
Strands between species do add and subtract base pairs. My point is the back of the deck is still the base of the tree regardless of how small or big the branches that stem from it become.
