What is the oldest lifeform (with a heart) on the planet earth? (not including plantlife and trees obviously)?

Question

C'mon, i need information to back up the answers.

Answer 1

Galapagos Toirtoises - One was recorded to have lived to 188 years old, and many live to 150 years old.

But someday, scientists will probably record that Sturgeons or similar fish can live as long or longer.

Answer 2

If you are considering animials which are long lived, go with Tu'i Malila, a radiated tortise, found by Captain Cook and was aboard the HMS Endeavor in 1777, she died in 1965.

This is contested however with Adwaita who was a Aldabra giant tortoise who may have been 250+ years old when he died in March of 2006..

If want celebrity go with Harriet, the Great Tortise who just died last June, she was found and collected by Charles Darwin himself in 1835.

If however, you're talking about the oldest lineage of organisms with a heart, probably you want to consider the lowly worm.

Worms evolved from simple filter feeders but eventually had to develop a circulatory system, the first occurance of that would have been in the worm, since they demonstrate (at the least) Bilateral symetry. Ironically bilateral symetry works because it allows organisms to become "damage resistant" loosing a leg is not necessarily fatal, but the Heart and Brain while both demonstrate bilateral qualities never evolved to be truly bilateral organs because damage to these organs was and is ususally invariably fatal.

While the modern acorn worm is probably the "oldest" possible candidate based on it's anatomy it's certainly one of the simplest and hence representative from the group of that probably was the oldest organism with a heart.

To respond properly to some other observations, other organisms like certain simple insects could be good candidates as well, horseshoe crabs are in a way like sharks and have evolved but kind of hit an "evolutionary" wall early on, because they are good at what they "have" to be good at - having other baby horseshoe crabs.

Sharks similarly have hit an evolutionary wall, in that their shape and muscloskeletal layout is darn near optimal for doing what they do. Which is a two step to success being a shark, killing other fish for food and having baby sharks.

Answer 3

that is rather possible in the immensity of the universe there are billions of earth-like planets until now existence won going. The evolution of existence is extremely understood apart from that preliminary spark whilst existence switched on. The earliest existence varieties we've fossil information for are far extra problematic than the traditional easiest living entities. So on the single hand, we'd have a statistical specific wager of planets very akin to the Earth, and on the different hand we with out subject don't be attentive to the probability of existence getting started, that are astronomically low. The manufactured from those 2 possibilities is uncertainty. So enable us to assume the spark of existence happens throughout circumstances are amiable, and there are billions of existence bearing earth-like planets with evolution in finished swing. i might say the prospect of any existence style such as people is extremely not likely even with the shown fact that achieveable. The human style has stepped forward by technique of way of standard determination over 3.5 billion years, and each and each adaption has been thoroughly unintended consistent with mutations and changing environments, so, the quantity of unique available outcomes might rival the quantity of stars in the universe. If smart existence has stepped forward in diverse places, that is maximum in all probability fully unique to humanoid style, purely as certainly one of those super variety of creatures right here in the international are. certainly, such extraterrestrial beings might properly have fullyyt diverse DNA, and to our eyes take place stranger than the oddest looking creature interior the international.

Answer 4

Horseshoe crab. A 450-million-year-old horseshoe crab is no different to specimens alive today. It has possessed the same complex features and equipment for the last half billion years or so. Clearly, at a time when—according to Darwinists—living things should have been evolving, no evolution actually took place.

Answer 5

probably a giant galapagos turtle. they live forever.

here is what wikipedia says:
They are commonly known as the world's longest living animals, with an average lifespan of 177 years.

Answer 6

Probably Crocodiles!

Answer 7

I assume you mean how old do individuals get to be?

It's a tie between man and whales.

Whales would surpass us easily if they had the kind of medical care, shelter, and nutrition that we do.

Answer 8

i believe its some kind of fish with armour like plating that lives deep in the ocean

Answer 9

I would imagine it being a parrot.... but I remember watching a man on TV who was about 114 recently.

Answer 10

Fish. They were around before the dinosaurs.
