Life originated in the early seas less than a billion years after the Earth was formed. Yet another three billions years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.

What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on megafossils - relatively large specimens of essential whole plants and animals. Vascular plants, related to modern seed plants and ferns, left the first comprehensive megafossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of 10 modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by the animals that preyed on the plant-eaters. Moreover, the megafossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago.

Recently, however, paleontologists have been taking a closer look at sediments below this Silurian- Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rock in an acid bath. The technique has uncovered new evidence from sediments that were deposited near the shores of the ancient oceans - plant microfossils and microscopic pieces of small animals. In many instances, the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of the fossils consist of the organic remains of the organism.

These discovered fossils have not only revealed the existence ofpreviously unknown organisms, but have also pushed back these dates for the invasion of land by multicellular organisms. Our view about the nature of the early plants and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms

According to the theory that the author calls "the traditional view", what was the first form of life to appear on land?

A. Bacteria

B. Meat-eating animals

C. Plant-eating animals

D. Vascular plants

Bài dịch

Sự sống khởi ngổn ở các vùng biển cổ khoảng một tỷ năm sau khi trái đất được hình thành. Tuy nhiên, phải ba tỷ năm sau đó thì thực vật và động vật đầu tiên mới xuất hiện trên thềm lục địa. Quá trình thay đổi từ cuộc sống dưới nước lên trên mặt đất có lẽ là một thách thức lớn của sự tiến hóa, giống như sự bắt đầu của sự sống vậy.

Sinh vật sống nào mà có thể tạo nên một bước ngoặt mạnh mẽ như vậy? Quan niệm truyền thống về các sinh vật trên cạn đầu tiên dựa trên megafossils - mẫu hóa thạch khá lớn của những loài cây và động vật quan trọng. Thực vật có mạch, liên quan đến những giống cây hiện đại và dương xỉ, là mẫu hóa thạch khổng lồ toàn diện đầu tiên được ghi lại. Chính vì lí do này, người ta cho rằng kết quả của việc di chuyển lên cạn đã phản ánh sự tiến hóa của 10 hệ sinh thái hiện đại trên cạn. Theo quan điểm này, thực vật có mạch nguyên thủy là nhóm đầu tiên lên bờ, theo sau là động vật ăn cỏ, và cuối cùng của động vật ăn thịt. Hơn nữa, các hóa thạch lớn này cũng cho biết rằng sự sống trên cạn xuất hiện và phát triển đa dạng mạnh mẽ vào khoảng giữa kỉ Silua và kỉ Devon, hơn 400 triệu năm trước một chút.

Tuy nhiên gần đây, các nhà khảo cổ đã nghiên cứu sâu hơn về lớp trầm tích dưới vùng ranh giới địa chất Silurian- Devon này. Hóa ra là một số hóa thạch có thể được tạo ra từ trầm tích bằng việc cho đá vào trong axit. Kỹ thuật này đã tìm ra bằng chứng mới về trầm tích lắng đọng gần bờ biển của các đại dương cổ đại- vì có thực vật và những phần nhỏ xíu của động vật. Trong nhiều trường hợp, các mẫu vật có đường kính còn bé hơn một phần mười của milimet. Mặc dù chúng bị chôn vùi trong các hòn đá hàng trăm triệu năm, rất nhiều các hóa thạch vẫn còn chứa đựng các bộ phận hữu cơ của sinh vật.

Những hóa thạch được phát hiện không chỉ tiết lộ về sự tồn tại của những loài sinh vật chưa từng được biết đến mà còn đẩy lùi trở lại ngày mà sinh vật đa bào xâm chiếm lục địa. Quan điểm của chúng ta về bản chất của những cộng đồng động thực vật đang được xem xét lại. Và với những nghiên cứu đó, chác chắn sẽ tiêp tục nảy sinh những suy đoán mới về sinh vật sống trên cạn đầu tiên
