Hi,

I am trying to do a graph for biology 1102, the problem it has been years
since I had the first half. if someone would please lead me in the right
direction for this data.

date frequency of L ( large wing size) frequency of l ( small wing size)

1949 0.3 0.7
1959 0.3 0.7
1969 0.4 0.6
1979 0.2 0.8
1989 0.3 0.7
1999 0.8 0.2

I need to see if the population is evolving? why or Why not?

Please help me

I am lost.
