Speed of Evolution
Description
Researchers studied the development of a fly (Drosophila subobscura)
that had been accidentally introduced from the Old World into North
America around 1980.
Usage
ex0918
Format
A data frame with 21 observations on the following 8 variables.
- Continent
a factor with levels "NA" and
"EU"
- Latitude
latitude (degrees)
- Females
average wing size (10^3\timeslog
mm) of female flies on log scale
- SE_Females
standard error of wing size (10^3\timeslog mm) of female flies on log scale
- Males
average wing size (10^3\timeslog
mm) of male flies on log scale
- SE_Males
standard error of wing size (10^3\timeslog mm) of male flies on log scale
- Ratio
average basal length to wing size ratios of
female flies
- SE_Ratio
standard error of average basal length to wing
size ratio of female flies
