All Life on Earth Today Descended from a Single Cell. Meet LUCA
- Veliladon 2y agoDo they live on the second floor?

- hulitu 2y ago> All Life on Earth Today Descended from a Single Cell. Meet LUCA I thought it was Adam. /d
- 01HNNWZ0MV43FF 2y agoLuca would be including non-human life
- andrewstuart 2y agoSo weird to think we share a ancestor with mushrooms, trees and jellyfish.
- lancesells 2y agoI was thinking about this the other day. Like how all of these different types of things splintered off and evolved in different ways. Trees are these creatures that grow their limbs into the earth and the sky rendering them immobile but they have the same ancestor as us.
- tonyedgecombe 2y agoThere is some speculation that the last common ancestor between us and fruit flies preceded the evolution of brains. If correct this means brains have evolved independently at least twice.
- sixothree 2y agoMultiple genesis events seems even weirder to me.
- Ekaros 2y agoOn other had think of DNA and start wondering would same mechanism appear multiple times independently.
- biomcgary 2y agoSo many assumptions are necessary for this type of research, particularly for the timing. Inferring such an early age depends on a "clock" that varies based on the stringency of purifying selection. I.e., it is only clock-like to the degree that competition and the level of biological systems integration were essentially static through time.
- Woodi 2y agoLUCA have 2600 genes ? How such thing can be even remotely called "first" ??
- zktruth 2y agoDid you skip breakfast or something? Where did you get "first" from "last"?
- fbarred 2y agoFrom the article: “It’s not the first cell, it’s not the first microbe, it’s not the first anything, really,” said Greg Fournier, an evolutionary biologist at the Massachusetts Institute of Technology.
- Woodi 2y agoArticle also says: "LUCA is the furthest point in evolutionary history that we can glimpse by working backward from what’s alive today." Which translates to: first in time, IMO But my point was: LUCA described here is realy complicated so why it makes some new quality ? Maybe some milestone, yes.
