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:
BMW
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.
g
KODAK
Does anyone know what the figure in the 60’s logo is supposed to be?
og
MICROSOFT
Is it me or this logo is boring?
og
PEPSI
Pepsi evolves, 11 logos in 111 years… not bad at all.
g
WAL-MART
How about the second and third typography. It is like the one used in the Wild West in the “WANTED” signs searching for criminals.
