1Maya and Daniel met their tutor on Tuesday to discuss their project on natural selection.
2They had originally planned to study finches, but the tutor suggested focusing on urban pigeons instead.
3Daniel admitted he had assumed evolution always made creatures bigger, which the tutor gently corrected.
4The tutor explained that selection simply favours whatever traits improve survival in a particular environment.
5Maya proposed collecting data in spring, though the field trip was eventually arranged for early autumn.
6It was not the equipment but the weather that worried the two students most.
7They agreed to photograph the birds rather than trap them, partly for ethical reasons.
8The tutor reminded them that a hypothesis must be testable, not merely interesting.
9Daniel initially wanted twenty sample sites, but time limits reduced the number to eight.
10Before leaving, they booked the laboratory for Friday to enter and check their measurements.
11Both students left the meeting feeling far more confident about the direction of their research.
