Multicellular Organisms Quotes & Sayings

Organs evolve to perform a particular function, but once they exist, they can be adapted for other usages as well. Mouths, for example, appeared because the earliest multicellular organisms needed a way to take nutrients into their bodies. We still use our mouths for that purpose, but we also use them to kiss, speak and, if we are Rambo, to pull the pins out of hand grenades. Are any of these uses unnatural simply because our worm-like ancestors 600 million years ago didn't do those things with their mouths? — Yuval Noah Harari

In nerve-free multicellular organisms, the relationships of the cells to each other can only be of a chemical nature. In multicellular organisms with nerve systems, the nerve cells only represent cells like any others, but they have extensions suited to the purpose which they serve, namely the nerves. — Otto Loewi

Throughout 150 years of the science of bacteriology, there is no evidence that one species of bacteria has changed into another ... Since there is no evidence for species changes between the simplest forms of unicellular life, it is not surprising that there is no evidence for evolution from prokaryotic [i.e., bacterial] to eukaryotic [i.e., plant and animal] cells, let alone throughout the whole array of higher multicellular organisms. — Alan H. Linton

I expected to be shot at any moment and if they had done I would have understood, that they couldn't take risks with someone foolhardy or so unpredictable. — Laurie Lee

Without programmed cell death, the bonds that bind cells in complex multicellular organisms might never have evolved. — Nick Lane

I'd give anything to make things right for you." He caressed my cheek, my hair, my back. Everywhere he touched, the angry fires cooled. I wished he'd touch my heart. "But I can't. I can help, but the hard work is all up to you. If you don't feel real, no one else can do it for you. I promise, though you've always felt real to me. From the moment I saw you jump off the cliff."
"Sometimes I feel like I'm still jumping off the cliff. — Jodi Meadows

We always come back to the same vicious circle - an extreme degree of material or intellectual poverty does away with the means of alleviating it. — Simone De Beauvoir

Yvette had never talked about her marriage - she was a smart girl, and she knew you had no right to complain about someone you got all the way to the altar with. You made that choice, even if you were a child when you did it, and the marriage vow was sacred. — Maile Meloy

As soon as we touch the complex processes that go on in a living thing, be it plant or animal, we are at once forced to use the methods of this science [chemistry]. No longer will the microscope, the kymograph, the scalpel avail for the complete solution of the problem. For the further analysis of these phenomena which are in flux and flow, the investigator must associate himself with those who have labored in fields where molecules and atoms, rather than multicellular tissues or even unicellular organisms, are the units of study. — John Jacob Abel

The snow again. White, white net of beauty, net of dream, trapping the earth, trapping the helpless heart of life ... — Martha Ostenso

Chromosomes. Sex. Grasshoppers. "Pick me up, Mommy."
This is an odd list, except in the eye of evolution. For in the major developments in the history of life, the ability to say, "Pick me up, Mommy" features prominently along with the emergence of genes, sexual reproduction, and multicellular organisms. On a smaller but no less wondrous scale, the ability to speak opens one mind to another. Babies announce their arrival with a loud cry, but it is their first words that launch the journey of a lifetime. — Charles Yang

The secret of health, happiness, and long life: If you simply learn how to accept and express love, you will live longer ... be happier ... grow healthier. For love is a powerful force. — Alfred Armand Montapert

How many abused souls - dogs and humans alike - have remained in an unloving place because staying was far less terrifying than leaving? — Ted Kerasote

If we thus recognise
that the aim is to equip the group with the
attributes of the individual, we shall be reminded
of a valuable remark of Trotter's, to the effect that
the tendency towards the formation of groups is biologically
a continuation of the multicellular character
of all the higher organisms. — Sigmund Freud

Actually, the entire ascent of life can be presented as an adaptive radiation in the time dimension. From the beginning of replicating molecules to the formation of membrane-bounded cells, the formation of chromosomes, the origin of nucleated eukaryotes, the formation of multicellular organisms, the rise of endothermy, and the evolution of a large and highly complex central nervous system, each of these steps permitted the utilization of a different set of environmental resources, that is, the occupation of a different adaptive zone. — Ernst W. Mayr

The superior man is he who develops, in harmonious proportions, his moral, intellectual, and physical nature. — Unknown
