Rumsfeld has to be pretty close.

The evolutionary history of penguins is poorly understood, as penguin fossils are rare. The oldest known fossil penguin species are the Waimanu, which lived in the early Paleocene epoch of New Zealand, about 62 million years ago. While they were not as well adapted to aquatic life as modern penguins (which first emerged in the Eocene epoch 40 million years ago), Waimanu were flightless and loon-like, with short wings adapted for deep diving. These fossils prove that prehistoric penguins were already flightless and seagoing, so their origins probably reach as far back as 65 million years ago, before the extinction of the dinosaurs. Penguin ancestry beyond Waimanu is not well known, though some scientists (Mayr, 2005) think the penguin-like plotopterids (usually considered relatives of anhingas and cormorants) may actually be an early sister group of the penguins, and that penguins may have ultimately shared a common ancestor with the Pelecaniformes.

If you want to know about a currently living tree, then this is it.  Ten thousand feet up in California's White Mountains lives the oldest living thing on Earth. It is a bristlecone pine that was around when the Egyptian Pyramids were built. Ironically, after weathering all the droughts, high winds, and lightning strikes that must have struck over the millennia, the nearly 5,000-year-old Methuselah Tree now faces threats from the one force of nature that seemingly can do it harm: people.

The largest is Tokyo, Japan.\n\nDamascus, Syria is the oldest.

Around 600,000 years old. Maybe even older.

Based on fossil, genetic, and molecular evidence, we have a long train of ancestors in our history.  Modern humans and other primates, such as monkeys, have a common ancestor that lived about 25 million years ago, and our ancestor would probably *not* be considered a "monkey."  Before that were early mammals, and before that mammal-like reptiles, the sauropsids. Before that were early reptiles, and amphibians.  And yes, before that, about 440 million years ago, one of our ancestors was a fish.  So you are correct.

4 Billion Years old, the oldest rocks (found in Canada and other places) are 4 billion years old.  Possibly all created when a huge planetoid crashed into the newly made earth.  This caused the whole planet to melt, created the moon, and cause the massive ammounts of iron on the earth to sink, due to its high desity and the melted earth, to the the core and create our magnetic field (the reason we can live).

Hylonomus lyelli and Paleothyris are the oldest-known true egg-laying reptiles. Their fossils have been found in 310,000,000-year-old coal deposits in Joggins, Nova Scotia. They were about 8 inches long in adulthood and looked like modern lizards. \n\nI couldn't pick them out of a lizard lineup, personally.

The oldest horse that ever lived was "Old Billy". He was born in Lancashire in 1760 and lived to the world record age for horses of 62 years!\n\nThe average life span of a horse is only 20. And that is actually quite old. 20horse years, would be like a human living to 100.\n\n-D

There are over two million species alive on earth right now. Which particular path do you want?\n\nFor humans, we know the progression through some crucial stages, but not the whole thing. For example, we have very good fossils for the transition between certain fish and amphibians, between reptiles and mammals, very good evidence for the last couple of million years. The early development of primates is being actively researched with a lot of interesting results.\n\nHere is the basic progression:\nLife started about 3.8 billion years ago\nEucaryotic life (with true nuclei) started about 2 billion years ago.\nMulti-cellular life started about 570 million years ago.\nThe first vertebrates were around 450 million years ago.\nThe developement of sarcopterygian fish was about 400 million years ago.\nDevelopment of labrynthodont amphibians from the sarcopterygian fish was about 360 million years ago. \nFirst reptiles from amphibians was about 320 million years ago.\nA wide variety of mammal-like reptiles developed in the time period between about 300 million years ago and 250 million years ago, with the cynodonts developing later. \nSmall, rodent-like mammsls developed from the cynodonts about 220 million years ago.\nSome very early primates developed around 60 million years ago from smallish rodent-like mammals.\nHomonoidae (apes) developed around 22 million years ago with Proconsul the type species.\nDryopithecus was around 17 million years ago in Africa and was an ancestor to most african apes.\nAustralopithecus developed about 4 million years ago in Eastern africa with Australopithecus afarensis the most likely human ancestor.\nBetween about 2 and 3 million years ago there were several hominid species in eastern and southern africa. The exact human ancestor is controversial since they are so similar.\nHomo habilus appeared about 2 million years ago and was replaced by Homoe erectus about 1.5 million years ago.\nHomo sapiens (modern humans) appeared about 300 thousand years ago in africa. There were other hominid species around at that time and later. For example Homo neanderthalensis was around until about 25 thousand years ago. Whether Neanderthals contributed to modern humans is another controverisal question.\n\nIt should be pointed out that the exact ancestral species may not be known. But it is typical for a variety of closely related species to develop in the fossil record at the same time. Figuring out which one is the actual ancestor for a given later species is not always possible given the fragmentary fossils available and our current knowledge of how structural changes occur in evolution.\nI hope this helps.

the earliest known form of life is cyanobacteria which grew in bluish green pod like colonies approximately 3.4 billion years ago.

It takes a very long time.  The oldest fossils are about 3.5 billion years old, but many are not nearly that old.  The youngest are probably only about 23 million years old or even less.\n\nThese links are helpful.
