This picture shows evolution by blending an ape and human face, showing their connection. The way the two faces merge shows how humans share a common ancestor with apes. The fossils below show changes in bones over time, like skulls and hands, proving the progression. These fossils show how features like brain size developed over time. The eye in the middle brings up the shared traits between species. The shading from one face to the other symbolizes the slow, step-by-step process of evolution over millions of years. It reminds us how small changes over time led to the diversity of life we see today.

Prokaryotes are unicellular organisms that lack a nucleus and membrane-bound organelles. They are divided into two domains: Bacteria and Archaea. For Example Escherichia coli (E. coli) is bacteria found in the intestines of humans and animals. While most types are harmless, some, like Shiga toxin-producing E. coli (STEC), can cause serious illness. STEC is often linked to undercooked meat, raw milk, or vegetables contaminated with animal feces. The bacteria mostly come from cattle but can also be found in other animals. People get sick from eating contaminated food, drinking dirty water, or coming into contact with infected animals or people. Symptoms include stomach pain, diarrhea (sometimes bloody), vomiting, and fever. Severe cases, especially in children and the elderly, can lead to kidney failure (HUS), which is life-threatening. To prevent infection, cook meat thoroughly (70°C or 160°F), wash produce, avoid cross-contamination, and wash your hands regularly. The WHO promotes food safety practices and helps manage outbreaks.
