All the aforementioned issues are marvelously settled by God's word on the origin and nature of human life. This sermon considers Genesis 1-2 and the story of the first man and woman. Numerous other issues are considered: Does Darwinian macro-evolution harmonize with the Biblical record of creation? Does Genesis 1 and 2 contain two separate and contradictory creation stories? Did the Sabbath predate the Law of Moses as a "creation ordinance"? What is God's design for the family? Please listen with a Bible in hand.
Note: after delivering this sermon I was informed that the Biblical classification of "kinds" it is actually larger than the biological classification of "species". Please forgive my ill-informed equation of the two. The argument of the fixity of the species should be worded, "the fixity of kinds" (i.e. one kind of animal, or life form, does not and cannot change into another "kind"). Here is a helpful article on the Kinds/Species issue - https://answersingenesis.org/natural-selection/speciation/species-and-kind/
