The biological pattern generation systems which produce stripes and spots have very little difference between them. As a result, sometimes the system shifts over to spots instead of stripes (or vice versa).

If you see a baby bear acting like this, the very best thing you can do for it is to scare the living bejeezus out of it.
It will grow up to be a large adult who is not afraid of people. It will get angry & hurt someone when it doesn't get what it wants. It will then be killed.

Two wide angle eyes (black), two telephoto eyes (orange), and then three more (blue).
The black are for getting around. The orange are for finding the ladies. I've no idea what the blue do, but they've got a more complex retina like ours. Most lenses have only a simple receptor.

If you find you can't understand people when they're wearing a mask, it's a sign you've been unconsciously lip-reading.
If you haven't had your hearing examined by a professional, it might be a good idea to do so. Some forms of hearing loss are progressive, but can be treated.
When I speak to people in public places, many will see my mask and automatically ask me to repeat myself before I even finish speaking.

So far the flowers have been underwhelming.
They do seem to have the delphinidin pigment responsible for the blue seed color, but color in petals is strongly impacted by pH because the petals are living tissue. The result is the best color so far is a reddish-purple.

Most of my space dedicated to beans this year is for an F2 population from a hybrid between my blue bush common bean (P. vulgaris) and a runner bean (P. coccineus).

Raising honeybees to save the bees is like raising chickens to save the birds.
I don't remember where I first came upon this comparison, but it has stuck in my head ever since.
How many times has it got to be said - honeybees are NOT in danger of extinction and keeping bees does NOT help the wild bees that ARE threatened! Honeybee hives have increased globally year on year and their presence in some areas threatens to bring diseases to wild bees.

Did you know that this is a misleading and often false statement? Green peppers will ripen to another color if they're mature enough at harvest. Different varieties will ripen to yellow, orange, red, or brown. One that turns fully yellow will not later turn orange or red.

Did you know that different colored peppers are just the same pepper in different stages of ripeness?
Red peppers are the most ripe and take much longer to harvest which is why they're more expensive than the other peppers!
