DNA. What is it made of? How does it makes us what we are? How and why do we share the same DNA with animals, plants, fruits, etc. ?
In: Biology
Regarding the sharing DNA with animals and planta and fruits:
If we think of DNA as the building blocks of life; we can actually observe we share many characteristics with many living things.
Moves around with muscles and bones in a general shape of a torso with a back spine, has 2 legs and 2 arms.
Breathes oxygen from air and exhales CO2 through the nose.
Has blood, a heart, veins and arteries.
Has a brain in the head, feeds by the mouth and defecates through the tush, has eyes that adapt to different light conditions, and so on.
As you can see all of those things are shared with MANY species so all of those could be similarities in the gene code.
Even if you said “but giraffes have such a long neck”. Fair, difference. But it’s the length; aside from a few much needed adaptations regarding the operation of such a long neck, it’s “just” a really long beck.
In the end, we are not too different from what sone people refer to as “non-human” animals; and our DNA shows it.
