Why are Some People Left Handed

Left Handedness

Being a righty or a lefty could be linked to variations in a network of genes that influence right or left asymmetries in the body and brain. Studies suggest that approximately 10% of the world population is left-handed. Cross-dominance or mixed-handedness is the change of hand preference between tasks.

Left-handed people haven't always been treated well throughout history.
There have been a few theories about where left-handedness comes from over the decades, including an outdated idea that it's something to do with mothers being stressed while pregnant.

But finally It's down to the spinal cord - not the Brain ...

Research since the 1980s has shown that our preference for being left or right-handed is probably determined in the womb before we are born, as early as the eighth week of pregnancy, according to ultrasound scans. From week 13 in the womb, babies tend to suck either their right or their left thumb.

They have a world-wide distribution and are commonly found living in soil, feeding on live and dead organic matter. An earthworm's digestive system runs through the length of its body. It conducts respiration through its skin. Lets learn some interesting facts about Earthworm Earthworms come in a seemly infinite variety—around 6,000 species worldwide.

The largest earthworm ever found was in South Africa and measured 22 feet from its nose to the tip of its tail. Worms tunnel deeply in the soil and bring subsoil closer to the surface mi
