Did all species evolve from one common ancestor? Genesis 1 repeats ten times that God created creatures separately according to various “kinds.” Today’s species show the potential variation that God designed within the original kinds, but this variety remains limited—cats are still cats, and dogs are dogs.
A biological kind is any group of organisms that are able to reproduce, either by breeding or some mechanism of self replication, if not for an intervening factor such as geography,habit, diet, sexual preference, environmental adaptation, recessive genetic mutations, damaged dna, or due to dna copying that does not self correct. A kind must have a Clinal correlation in variety in their biology, anatomy, skeletal construction, capability of movement, natural posture, physical potential, natural locomotion and appearance.
A kind must have, unless hindered by genetic mutations, a Clinal correlation in it's variety of intelligence, intellectual capability, and levels of understanding.
