एक काल्पनिक जैविक घटना जिसके द्वारा जीवित जीवों को नॉनलिविंग मामले से बनाया जाता है

Noun:

जीवोत्पत्ति,

abiogenesis शब्द के हिंदी अर्थ का उदाहरण:

जीवोत्पत्ति के अध्ययन के लिए मुख्यतः तीन तरह की परिस्थितियों का ध्यान रखना पड़ता है: भूभौतिकी, रासायनिक और जीवविज्ञानी।

जीवोत्पत्ति की आदिम अवस्थाओं में पृथ्वी का वातावरण अनिश्चित और भौगोलिक परिवेश आज जैसा नहीं था।

इन नम इलाकों में इस बात पर अनुसन्धान ज़ारी है कि कैसे समुद्रों में अजीवजनन आरंभ हुआ होगा और इस अध्ययन का खगोलिकीय जीवोत्पत्ति को समझने में कैसे इस्तेमाल किया जा सकता है।

साधारण जीवोत्पत्ति दूसरे कल्प में हुई, जिसका नाम आर्किओज़ोइक (Archeozoic) है।

জজজ

जीवोत्पत्ति पृथ्वी पर अनुमानित ३.८ से ४ अरब वर्ष पूर्व हुई थी।

अजीवात् जीवोत्पत्ति (निर्जीव से जीवन की उत्पत्ति ; Abiogenesis) सरल कार्बनिक यौगिक जैसे निर्जीव पदार्थों से जीवन की उत्पत्ति की प्राकृतिक प्रक्रिया को कहते हैं।

abiogenesis's Usage Examples:

Such intermediate stages may have existed in the past, and the modern refutation of abiogenesis has no application to the possibility of these having been formed from inorganic matter at some past time.

The refutation of abiogenesis has no further bearing on this possibility than to make it probable that if protoplasm ultimately be formed in the laboratory, it will be by a series of stages, the earlier steps being the formation of some substance, or substances, now unknown, which are not protoplasm.

From the 17th century onwards it was gradually shown that, at least in the case of all the higher and readily visible organisms, abiogenesis did not occur, but that omne vivum e vivo, every living thing came from a pre-existing living thing.

Under the heading of Abiogenesis is discussed the series of steps by which the modern acceptance of biogenesis and rejection of abiogenesis has been brought about.

Huxley, who took a large share in the process of refuting contemporary abiogenesis, have stated their belief in a primordial archebiosis.

The first step in the scientific refutation of the theory of abiogenesis was taken by the Italian Redi, who, in 1668, proved that no maggots were "bred" in meat on which flies were prevented by wire screens from laying their eggs.

Parker (Elementary Biology) cites a passage from Alexander Ross, who, commenting on Sir Thomas Browne's doubt as to "whether mice may be bred by putrefaction," gives a clear statement of the common opinion on abiogenesis held until about two centuries ago.

van Leeuwenhoek discovered bacteria, and it was soon found that however carefully organic matter might be protected by screens, or by being placed in stoppered receptacles, putrefaction set in, and was invariably accompanied by the appearance of myriads of bacteria and other low organisms. As knowledge of microscopic forms of life increased, so the apparent possibilities of abiogenesis increased, and it became a tempting hypothesis that whilst the higher forms of life arose only by generation from their kind, there was a perpetual abiogenetic fount by which the first steps in the evolution of living organisms continued to arise, under suitable conditions, from inorganic matter.

Pasteur that the occurrence of abiogenesis in the microscopic world was disproved as much as its occurrence in the macroscopic world.

So far the theory of abiogenesis may be taken as disproved.

abiogenesis's Meaning':

a hypothetical organic phenomenon by which living organisms are created from nonliving matter
