It is not the case that Phylogenetic species concepts define species membership via intrinsic genealogical history, not reproductive relations.

Set your confidence on the premises below to see your aggregate.
Reasons For
1 perspective
Reason for
?
1.
Genealogical boundaries require arbitrary cutoff points in continuous lineages; reproductive isolation provides biological boundaries organisms actually maintain.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
Phylogenetic species concepts multiply species indefinitely as any small genetic divergence marks lineage splitting, making the concept practically useless.
?
How convincing is this?
Think about whether this reason is strong or weak
3.
Species' adaptive coherence and ecological role—central to why species matter—track reproductive isolation better than genealogical branching points.
?
How convincing is this?
Think about whether this reason is strong or weak
Reasons Against
1 perspective
Reason against
?
1.
Genealogical history is empirically traceable through genetic data, whereas reproductive isolation is often unobservable across extinct lineages.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
Asexual, parthenogenetic, and ancient organisms lack reproductive relations but have clear genealogical histories deserving species classification.
?
How convincing is this?
Think about whether this reason is strong or weak
3.
Reproductive concepts fail for geographically isolated populations that could interbreed but never do, yet phylogenetics avoids this arbitrariness.
?
How convincing is this?
Think about whether this reason is strong or weak
