This principle not only applies for living things, it also applies for companies, personal relationships and even for logos.
To prove it, here are a few examples:
Back to basics, more than 80 years of history and the logo returned to its original version, well it actually didn’t change much in all these years.
Does anyone know what the figure in the 60’s logo is supposed to be?
Is it me or this logo is boring?
Pepsi evolves, 11 logos in 111 years… not bad at all.
How about the second and third typography. It is like the one used in the Wild West in the “WANTED” signs searching for criminals.
