***** Your Knowledge Cases

In the first case, 200 guppies were moved from the base of a 20foot w*****terfall. Over a period of time, I would im*****gine that the guppies would have evolved slightly in order to survive ********** new habitat. Whereas they were dealing with a pred*****tor that fed on adult guppies, in their new home, ***** new predator feeds ***** the young.

***** order to survive ***** sexual maturity, *****se guppies must have adapted by being able to reach ***** faster. Evolution works at vari***** tempos (Rates ***** Change 7) and considering the small population of *****, in this case, ********** evolution process ***** ***** been very rapid- a form of Adaptive Radiation (R*****om Model 26).

The number ***** offspring must have also increased to allow for more favorable odds in maturing guppies. Young ***** living in this ***** ***** were also probably slightly bigger as ***** confuse the killifish ********** thinking it was an adult (R*****dom ***** 18-22).

In the second case, where the nematode parasite was found in some male jungle fowl, this is an example of 'natural selection' (Darwin Published ***** Origin of Species 1859). The parasite affects the eye *****d comb of the male fowl ***** makes it unattractive to females. Gradually these male ********** will disappear as they are not reproducing enough (or at all) and with them the gene that ***** their resistance to the parasite weaker. Eventually, ***** nematode parasite could find itself becoming extinct because only those resistant to it would be reproducing ***** surviving.

It is also possible that the nema*****de parasite may adapt to it's changing surroundings and ***** other ways to break the resistance of the male ***** fowls that are not currently affected *****
