Or run in a family? I just found out that quite a few people in my (immediate) family have O Negative blood. My dad and his father, me and my son and my sister too. I only found out that she’s the same type when she asked me if I had to get a Rhogam shot when I was pregnant. Is it just me or does there seem to be a lot of O Negative is in my family?

Hmm... so you can prove mokeys were really becomming man over billions of years but we don't have a single real fossle of it. And for some reason we all have the same body parts EVEN THOUGH it was all chance. Somehow chance figured out a way to bend light and invent the eye ball... Some how chance figured out how to manipulate sound and create an ear.

This website makes a lot of sence to any one who doesn't think evolution is the answer.

Ants and aphids appear to have mutualistic relationsips. Ant's stroke aphids with forelegs and antennae to get them to secrete droplets of parly digested plant sap. It is thougth that the aphids lose nothing because the sap is high in sugars and low in amino acids so the aphids ingest more sugar then they need. In retun for the sugar, the ants protect the aphids form their enemeites such as wasps and beetles. Resluts show that in some circumstances it is mutual while in others the relationsship is commensal with only the ant recieving a benefit.

So what situation would make this situation commensal?
