  Anagenesis
When the population of an entire species changes on a genetic level without a split, it is called anagenesis, phyletic evolution, or simply evolution.
The opposite of anagenesis, cladogenesis, is when a species splits into two genetically-distinct populations adapted to different ecosystems or survival strategies.
Taxonomists, when determining whether a species has indeed drifted enough from the ancestral population through anagenesis to be considered a new species, may look for differences in both behavior and structure of an organism, especially on a genetic level.

 Anagenesis Summary
Evolutionary taxonomists such as Simpson use both cladogenesis and anagenesis in their classifications, arguing that taxonomic groups should be based on the branching points in evolution and the degree of difference between groups.
Anagenesis also know as "Phyletic change" is the progressive evolution of species involving a change in gene frequency in an entire population rather than a cladogenetic branching event.

 Macroevolution: Its definition, Philosophy and History
Creationists often assert that "macroevolution" is not proven, even if "microevolution" is, and by this they seem to mean that whatever evolution is observed is microevolution, but the rest is macroevolution.
In this example, species A anagenetically changes over time to become species B, while species B cladogenetically changes over time by splitting into species C and D, neither of which are very different from B or each other.
Anagenesis is not regarded by most scientists as "real" speciation, although it is indistinguishable in the fossil record from a cladogenetic event.

 The Clovis First/ Pre-Clovis Problem: 2004 Revisit
Anagenesis is "directional evolution of a character, combination of characters, or a species within a lineage without diversification, or branching, of the lineage" (O'Brien and Lyman 2000:397).
Yes, I am aware that anagenesis and cladogenesis are biological concepts and projectiles do not breed.
Still, in this webpage I have chosen to apply these concepts to projectile type change through time.

  Cladistics - EvoWiki   (Site not responding. Last check: )
A perfect example would be Deinonychosauria and Avialae, or humans, and chimps.
Anagenesis is a comparatively simple process whereby one taxon is the phyletic progenitor of another: a linear progression from one form to another without divergence between lineages.
Due to this bias of cladistics, the term grade, introduced above, has also been applied to taxa, which display anagenetic change over time, and lack a branching component in their phylogeny.

Thus gaps in the hominid fossil record, if filled, would tend to show a phyletic continuum between related taxa (see also anagenesis and Evolutionary Synthesis; contrast to Punctuated Equilibrium).
Replacement Theory: Specific theory based on mtDNA evidence that all modern humans are descended from an African population, who replaced all other Homo populations after 200,000 BP.
Related to general theory that speciation results from adaptive radiation and cladogenesis, frequently with rapid replacement of one species by another (see also Punctuated Equilibrium; contrast to anagenesis).
