Instead, it favors attributes which are effective (which is, help an organism endure and reproduce extra efficiently than its friends) in a particular ecosystem. Characteristics which have been beneficial in a single natural environment may essentially be dangerous in One more.
Random mutations which might be passed on to offspring normally take place inside the germline, or sperm and egg cell lineage, of organisms. Sexual replica "mixes and matches" gene variants for making additional variation.
