根据下面的新闻材料，拟写一条一句话新闻。（不超过35字）

　　本报讯（记者姜澎）河南安阳发现的到底是不是真正的曹操墓？生性多疑的曹操真有七十二疑冢？面对各界持续不休的争论，生命科学家决定不再袖手旁观——复旦大学现代人类学教育部重点实验室近日宣布，向全国征集曹姓男性参与Y染色体检测，以期通过检测这些男性的Y染色体类型并进行归类，然后借助序列比对的方式，推测曹操应有的Y染色体特征，用DNA技术来解答曹操墓真伪之问。实验室有关负责人表示，目前数据库里的曹姓男子Y染色体数量十分有限，因此实验室希望能够征集到大量的曹姓男子Y染色体类型，进行测序分类，然后推断曹操应有的特征标记，并检测发掘出的曹操墓遗骨的Y染色体是否具有这些标记，再结合曹氏家族的分布和迁移情况，应该可以得到一个科学的结论。
