Guinnea pigs are great. I had one named Rosaland when I was a child.


I find it  sickening that some humans don't think that animals have feelings and intellegence.

One of my arguments against a "god'  is that a humane  'god' wouldn't make animals carniverous.

We are learning that even grass comunicates to warn of danger.

None the less there are too many humans on the planet such that it is no longer sustainable.

So very interesting.

I also saw a PBS program showing crows using tools as well.

Chimpanzees and monkeys have entered the Stone Age  AUG 26

Up until very recently, humans were thought to be the only animals who made and used stone tools, an era in human development that began roughly 3.3 million years ago. But according to this piece at the BBC, some chimpanzees and monkeys in various places around the globe have been using primitive stone tools for hundreds or even thousands of years.

Boesch and his colleagues had previously studied modern chimpanzee stone tool culture in the region. This research revealed that the chimpanzees have an idiosyncratic way of choosing and using their tools.

For instance, chimpanzees will often deliberately opt for particularly large and heavy stone hammers, between 1kg and 9kg, while humans prefer to use stones that weigh 1kg or less. Many of the 4300-year-old stone tools weighed more than 1kg, suggesting they were used by chimpanzees.

Chimpanzees also use their stone tools to crack open certain types of nuts that humans don't eat. Starch residues on some of the ancient tools came from these nuts.

Together, these findings led to an obvious conclusion: chimpanzees have been using stone tools in the rainforests of Ivory Coast for at least 4300 years.

Should be a more than loud ''A-HA' moment, I'd say.

See what can happen when you rely on science and not religion.

So the only sibling I have is an adopted brother who they immediately expected me to look after when I didn't have to be in school.

You win, cant compete with that.

Mother had 9 miscarriages after I was born, & I spent many years wishing I had been one of them.

Comment by Stephen Brodie on July 20, 2015 at 7:26pm

We sound like those old Yorkshire men from the Monty Python sketch competing for who had the worst childhood. I'm not usually this curmudgeon.  

Comment by Mrs.B on July 20, 2015 at 6:52pm

I was always picked last for anything requiring a team, so I was a loner right from the beginning. It took decades for me to realize I preferred it that way.

I found out long after I was married that many of my husband's relatives said my ''parents'' acted like they couldn't wait to get rid of me, & were handing me over on a silver platter. Nice huh?

I then made it my business to stretch the pay cheques as far as possible & raised 3 kids on one wage. I sewed, knitted, cooked from scratch, & our entertainment was a deck of cards for many years.
