What were the first animals? The fierce sponge-jelly battle that just won't end

Which animals came first? For more than a century, most evidence suggested that sponges, immobile filter-feeders that lack muscles, neurons and other specialized tissues, were the first animal lineages to emerge. Then, in 2008, a genomic study pointed to a head-scratching rival: dazzling, translucent predators called comb jellies, or ctenophores, with nerves, muscles and other sophisticated features. That single study ignited a debate that has raged for nearly 20 years, sparking fierce arguments about how complexity evolved in animals.

Why You Need To Snip Off Just One Corner Of Your Kitchen Sponge - Tasting Table

When your sponge becomes so dirty and full of bacteria that it's potentially dangerous, consider repurposing it by cutting off a corner. This helps you distinguish an everyday utility sponge from one used for dishes. Store your clipped sponges away from the kitchen sink, separate from the sponge you use to wash dishes. That way you won't be tempted to grab it by accident, nor will anyone else.
