我们报告的结果举行了一个研讨会，讨论进化生物学，古生物学和古生态学的问题，可以解决的科学钻探项目在坦噶尼喀湖，最大的，最深的和最古老的非洲裂谷湖。坦噶尼喀湖对进化生物学家来说具有特殊意义，因为它拥有地球上最壮观的地方性动物群之一，其中有数百种独特的鱼类、软体动物、甲壳动物和其他生物，它们在湖泊悠久的历史中进化而来。这些生物群中的大多数都是从湖中的短岩心化石中发现的，这增加了从长岩心中恢复身体化石和古代DNA记录的可能性。该湖的沉积记录还可以提供自中新世晚期以来非洲陆地生态系统历史的记录。这次为期3天的研讨会汇集了有关坦噶尼喀湖及其周边地区的生物和地质专家，以确定最终可纳入坦噶尼喀湖总体钻探计划的古生物学、生态学和微生物目标的优先次序，并考虑如何将生物目标有效地纳入先前研讨会已考虑过的坦噶尼喀湖钻探项目的古气候和构造目标。
We report on the outcomes of a workshop held to discuss evolutionary biology, paleobiology and paleoecology questions that could be addressed by a scientific drilling project at Lake Tanganyika, the largest, deepest and oldest of the African Rift Valley lakes. Lake Tanganyika is of special significance to evolutionary biologists as it harbors one of the most spectacular endemic faunas of any lake on earth, with hundreds of unique species of fish, molluscs, crustaceans and other organisms that have evolved over the lake's long history. Most of these groups of organisms are known from fossils in short cores from the lake, raising the possibility that both body fossil and ancient DNA records might be recovered from long drill cores. The lake's sedimentary record could also provide a record of African terrestrial ecosystem history since the late Miocene. This 3-day workshop brought together biological and geological specialists on the lake and its surroundings to prioritize paleobiological, ecological and microbiological objectives that could ultimately be incorporated into an overall drilling plan for Lake Tanganyika and to consider how biological objectives can effectively be integrated into the paleoclimate and tectonics objectives of a Lake Tanganyika drilling project already considered in prior workshops.
