How to use this page well
These pages work best when they behave like tools, not essays. Use the quick structure first, then apply it to the exact journal and manuscript situation.
Question | What to do |
|---|---|
Use this page for | Getting the structure, tone, and decision logic right before you send anything out. |
Most important move | Make the reviewer-facing or editor-facing ask obvious early rather than burying it in prose. |
Common mistake | Turning a practical page into a long explanation instead of a working template or checklist. |
Next step | Use the page as a tool, then adjust it to the exact manuscript and journal situation. |
Quick answer: A Molecular Biology and Evolution cover letter is a one-paragraph significance argument: name the evolutionary discovery or methodological advance, explain why it matters beyond one dataset or clade, confirm author approval, and disclose related work, AI use, and prior-review context where applicable.
The official MBE author guidelines require this letter. Use the MBE submission guide for ScholarOne, files, code/data, and the overall molecular-evolution fit decision, or the MBE journal route for journal context.

What the current MBE guidance requires
Requirement | Letter action |
|---|---|
Cover letter required | Give a concise one-paragraph value argument. |
Significant discovery or methodological advance | State what changes in molecular-evolution understanding or inference. |
Broader impact | Explain why the result travels beyond one species, locus, or descriptive dataset. |
All authors approved | Include an explicit approval assurance. |
Related work disclosure | List and distinguish overlapping preprints, papers, datasets, and reports. |
AI-use disclosure | Keep the letter and Methods/Acknowledgements disclosure consistent. |
Previous reviews | Name the prior journal, reviews, and point-by-point response. |
MBE's cover letter is not the place to reproduce the abstract. It gives the editorial board the short reason a result clears the journal's molecular-evolution bar rather than being a descriptive genomics, general genetics, or tool-only paper.
This page was researched against the live MBE author guidelines on July 15, 2026. Use this page before you submit to test the letter's evolutionary claim, its evidence boundary, and the disclosures that belong with it; use the linked submission guide for the broader upload package.

Dear Molecular Biology and Evolution Editors,
Please consider our manuscript, "{full title}," for Molecular Biology and
Evolution. We report [MBE DISCOVERY OR METHOD ADVANCE], showing that {central
evolutionary result} changes how {evolutionary process, lineage history,
selection, adaptation, population history, or molecular mechanism} is
understood.
The broader impact is {reason the result extends beyond one dataset or clade}.
The evidence is in {key analysis, validation, simulation, figure, data set, or
code repository}; the manuscript is not only descriptive because {causal or
general evolutionary inference}.
All authors have read and approved the final manuscript. This work has not been
published previously and is not under consideration elsewhere. Related work,
preprints, overlapping data, AI use, conflicts, and prior-review context are
disclosed here: {disclosure or none}. For a transfer, we include the prior
journal, reviews, and point-by-point response.
Sincerely,
{corresponding author name, affiliation, email}The MBE-specific opener
Weak: We generated a large comparative genomics dataset for a poorly studied clade.
Stronger: We show that recurrent shifts in mutation spectrum, rather than demographic history alone, explain the accelerated amino-acid substitution rate across three independently evolved high-altitude lineages, supported by phylogenetic models, simulation, and population-genetic controls.
The stronger version identifies the evolutionary claim, comparison basis, inference, and evidence. It does not ask an editor to infer broad value from scale alone.
In our pre-submission review work with MBE-targeted manuscripts
Across our MBE pre-submission reviews, the recurring problem is that a technically strong sequence, phylogenomic, population-genetic, comparative-genomics, molecular-adaptation, or method paper is framed as a data product instead of an evolutionary inference. The cover letter is the quickest place to expose that distinction.
Molecular Biology and Evolution descriptive-dataset pattern
For Molecular Biology and Evolution, an expanded genome panel, tree, alignment, scan, or catalog is not enough by itself. The letter should say what evolutionary mechanism, process, history, rate, selection pressure, or generalizable inference the data resolve, and point to the figure, model, simulation, or control that supports it.
Molecular Biology and Evolution method-without-biological-payoff pattern
An improved algorithm can be valuable but still belong in a methods or bioinformatics venue if the letter never explains what it changes for evolutionary biology. State the benchmark, error mode, data regime, and biological inference the method enables. Do not call a faster pipeline a discovery without an evolutionary consequence.
Related-data boundary is vague
MBE explicitly requires disclosure of similar work and data. Identify preprints, dissertations, companion manuscripts, published analyses, and overlapping datasets, then explain the difference. That clarity is stronger than a generic originality sentence.
AI disclosure is split across the package
If AI helped generate content, images, code, translation, or processing, the MBE guidance requires disclosure in both the cover letter and Methods or Acknowledgements. Use matching wording and retain human responsibility for the scientific claims.
The practical editorial question behind all four patterns is simple: can the stated advance be checked in the manuscript without an editor having to reconstruct the argument? A letter that names an evolutionary process, says which comparison or control rules out the nearest alternative, and points to the relevant analysis helps. A letter that uses only importance language leaves the central route unresolved.
What makes an MBE cover letter fail
Dataset scale is substituted for an evolutionary claim. A new clade, assembly collection, or alignment is introduced as the advance, but the letter never identifies a process, prediction, or inference that changes because the data exist. State the question the data resolve and the evidence that supports the answer.
The method is faster but its practical utility is absent. MBE's Methods route calls for broad interest and a demonstration of robustness and practical utility through simulations or data analysis. A useful letter names the prior failure mode, comparison with current practice, and the molecular-evolution conclusion that becomes more reliable.
Related work is described as different without a boundary. A preprint, dissertation, companion manuscript, or overlapping dataset is acknowledged but not distinguished. State exactly what overlaps and what differs, then supply the requested related material. MBE screens for redundant publication, so a vague originality assertion is not a substitute.
Reviewer suggestions look strategic rather than objective. MBE says authors may suggest reviewers, but selection is not guaranteed. Suggest people with the needed expertise who can provide an objective assessment and who have no financial or interpersonal conflict with any author. The journal says peer review is typically sent to 2 reviewers; do not treat suggested names as a promise about the review panel.
A transfer conceals its review history. When the paper was reviewed elsewhere, MBE asks for the previous journal, reviews, and a point-by-point response in the cover letter. A candid transfer statement makes it easier for an editor to decide whether the revised manuscript should be assessed further or re-reviewed.
Submit if
- the first paragraph identifies an evolutionary discovery or methodological advance
- the broader impact reaches beyond one descriptive dataset
- figures, models, controls, simulations, code, and data support the stated inference
- all authors approved the final manuscript
- related work, AI use, and transfer reviews are disclosed where relevant

Think twice if
- the letter works after replacing MBE with any genomics journal
- novelty means only more sequences, taxa, or compute
- a method benchmark lacks biological or evolutionary consequence
- related datasets or preprints would surprise the editor
Choose the MBE route honestly
If the manuscript's main value is | Cover-letter route | Think twice about MBE when |
|---|---|---|
A molecular-evolution inference | Name the process, general inference, and evidence that separates it from description. | The paper inventories variation without changing an evolutionary explanation. |
A phylogenetic or population-genetic method | Name the known failure mode, benchmark regime, and biological inference enabled. | The method is faster but does not improve an evolutionary conclusion. |
Comparative genomics or adaptation | State the repeated comparison, control, and process-level conclusion. | More genomes or taxa are the only novelty. |
A narrow genomic resource | Explain the evolutionary question it resolves or consider a resource, genomics, or data-focused venue. | The paper has no general molecular-evolution implication. |
The useful route sentence is precise: “This is MBE-shaped because the analysis distinguishes selection from demography across independent lineages under matched controls.” The weak route sentence is merely “This work is important for evolution.” The first tells an editor what can be checked in the methods, results, figures, and code. The second asks the editor to supply the reasoning.
Related work, data overlap, and AI use
MBE's disclosure rule is stricter than a generic statement that the work is original. Before sending the letter, make a short overlap ledger. Include a preprint disclosure, thesis chapter, conference report, previous paper, companion manuscript, reused alignment, subset or superset of samples, shared reference genome, and shared code base when it is materially related. Then write one sentence saying what the submitted paper adds: a new evolutionary question, model, data type, comparison, validation, or inference. Put the full citations and any required files where ScholarOne requests them.
AI disclosure needs the same discipline. If a tool helped draft prose, translate text, write or revise code, process data, create an image, or otherwise contributed to manuscript preparation, the current official guidance calls for disclosure in the letter and the Methods or Acknowledgements. State the actual role, retain human responsibility for the scientific claims, and ensure the two disclosures agree. Do not use the cover letter to imply that an AI tool established an evolutionary inference.
A practical last-pass check
- The title, abstract, one-paragraph letter, first figure, and discussion name the same evolutionary question.
- The letter says what the result changes beyond the immediate species, gene family, genome set, or dataset.
- The model assumptions, controls, simulation, robustness analysis, and code/data record can support the exact claim in the letter.
- Similar work and data are disclosed with a concrete difference statement.
- Every author has read and approved the final manuscript.
- AI use, conflicts, prior reviews, and transfer context are consistent across the letter and submission fields.
For MBE, specificity is more persuasive than superlatives. A compact statement of evolutionary inference, evidence, and disclosure boundary gives the editorial board a reason to send the work forward without disguising a descriptive result as a general discovery.
Frequently asked questions
Yes. Molecular Biology and Evolution's current OUP author guidelines require a cover letter for submission.
Keep it to the one-paragraph significance argument requested by the journal, plus necessary disclosures.
No. Explain evolutionary significance, broader impact, and disclosure context rather than reproducing the abstract.
Yes. MBE says authors may suggest potential reviewers at submission, but it does not guarantee they will be selected. Suggested reviewers should be objective experts without financial or interpersonal conflicts.
State whether the manuscript is a Discovery, Method, Resource, or other eligible type, and use the fit argument appropriate to that type.
Address the Molecular Biology and Evolution Editors unless the journal gives you another instruction. The official guidance describes single-anonymized review, but does not say that the cover letter is shared with reviewers; treat it as an editor-facing document.
Yes. The submitting author must disclose related or similar preprints, dissertations, manuscripts, published papers, and reports using substantially similar content or data, and explain the difference.
Yes. The current MBE guidance says AI use should be disclosed in the cover letter and in the Methods or Acknowledgements section.
Include the prior journal, previous reviews, and a point-by-point response in the cover letter.
