DToL Project's Biodiversity Goal

The Darwin Tree of Life (DToL) project is a major international initiative focused on biodiversity. It aims to sequence the genomes of life forms across the planet.

Primary Aim of DToL

The primary goal of the Darwin Tree of Life project, particularly in its initial phases, is stated as:

• To sequence the genomes of all eukaryotic species in Britain and Ireland.

This objective forms a significant part of the project's contribution to global biodiversity cataloguing.

Reasoning for Primary Aim

Option C Analysis:

• Focus on Sequencing: The DToL project centres on DNA sequencing to create a comprehensive genetic reference library.
• Eukaryotic Species: It targets eukaryotes, which include animals, plants, fungi, and protists – the vast majority of complex life.
• Geographical Scope (Initial Phase): The sequencing of species within Britain and Ireland represents a major, foundational phase of the DToL initiative. This detailed regional focus enables the development of methods and standards applicable to a global scale.
• Biodiversity Initiative: This aligns directly with the project's role as an international biodiversity initiative, contributing foundational data for understanding and conserving life.

Why Other Options Are Incorrect

• Option 1: Relates to human genetics and rare diseases, not the broad biodiversity focus of DToL.
• Option 2: Concerns crop engineering, a specific application rather than the primary aim of comprehensive species genome sequencing.
• Option 4: Deals with paleo-genetics and human migration, which is distinct from DToL's focus on current biodiversity.
