What are the noteworthy differences between the two? a) Yes, all individuals can change a little and pass those changes on to their offspring. Is it possible for two different genes to imply different phylogenetic relationships among a group of species? There is similar variety for wings and head color, creating an almost mix-and-match effect when the species are viewed side by side.

Why is our DNA so similar to all other living organisms? or nec facilisis. Olfspring must be similar to their parents due to shared genes. And yet, at the genetic level they are up to 99.97% identical. In evolutionary biology, reciprocal altruism is a behaviour whereby an organism acts in a manner that temporarily reduces its fitness while increasing another organism's fitness, with the expectation that the other organism will act in a similar manner at a later time..
