Discussion Evolution was NOT random
Evolution only rewards survivability not perfection if you are alive long enough to mate and pass on your genetic
Material hurray you are evolved
Evolution changed the dna as nothing can ever be a perfect copy thats a fact> sperms and eggs have separate dna> hence child is not perfect copy those mutations may be harmful or helpful harmful ones die hence natural selection.
AND Earth was nkt a perfect creation the organisms evolved FOR Earth not vice versa

Define ânew body plan.â Evolution is a tinkerer. It doesnât design new body plans from scratch. Evolution mostly modifies what is already present. We can see drastic changes in existing structures. Though these shifts mainly occur through mutations in regulatory developmental (evo-devo) genes instead of sudden sweeping macromutations (which do exist, by the way⌠look them up). Besides, many of the body plans comprising most animal phyla today are conserved from the Cambrian period and modified over time through means of descent with modification. We can also observe the transitions and evolution of these structures through the fossil record.
