Lamarck, the Founder of Evolution: His Life and Work

CHAPTER I. Birth, Family, Youth, and Military Career

BIRTH, FAMILY, YOUTH, AND MILITARY CAREER

The life of Lamarck is the old, old story of a man of genius who lived far in advance of his age, and who died comparatively unappreciated and neglected. But his original and philosophic views, based as they were on broad conceptions of nature, and touching on the burning questions of our day, have, after the lapse of a hundred years, gained fresh interest and appreciation, and give promise of permanent acceptance.

The author of the Flore Française will never be forgotten by his countrymen, who called him the French Linné; and he who wrote the Animaux sans Vertèbres at once took the highest rank as the leading zoölogist of his period. But Lamarck was more than a systematic biologist of the first order. Besides rare experience and judgment in the classification of plants and of animals, he had an unusually active, inquiring, and philosophical mind, with an originality and boldness in speculation, and soundness in reasoning and in dealing with such biological facts as were known in his time, which have caused his views as to the method of organic evolution to again come to the front.

As a zoölogical philosopher no one of his time approached Lamarck. The period, however, in which he lived was not ripe for the hearty and general adoption of the theory of descent. As in the organic world we behold here and there prophetic types, anticipating, in their generalized synthetic nature, the incoming, ages after, of more specialized types, so Lamarck anticipated by more than half a century the principles underlying the present evolutionary theories.

So numerous are now the adherents, in some form, of Lamarck's views, that at the present time evolutionists are divided into Darwinians and Lamarckians or Neolamarckians. The factors of organic evolution as stated by Lamarck, it is now claimed by many, really comprise the primary or foundation principles or initiative causes of the origin of life-forms. Hence not only do many of the leading biologists of his native country, but some of those of Germany, of the United States, and of England, justly regard him as the founder of the theory of organic evolution.

Besides this, Lamarck lived in a transition period. He prepared the way for the scientific renascence in France. Moreover, his simple, unselfish character was a rare one. He led a retired life. His youth was tinged with romance, and during the last decade of his life he was blind. He manfully and patiently bore adverse criticisms, ridicule, forgetfulness, and inappreciation, while, so far from renouncing his theoretical views, he tenaciously clung to them to his dying day.

The biography of such a character is replete with interest, and the memory of his unselfish and fruitful devotion to science should be forever cherished. His life was also notable for the fact that after his fiftieth year he took up and mastered a new science; and at a period when many students of literature and science cease to be productive and rest from their labors, he accomplished the best work of his life--work which has given him lasting fame as a systematist and as a philosophic biologist. Moreover, Lamarckism comprises the fundamental principles of evolution, and will always have to be taken into consideration in accounting for the origin, not only of species, but especially of the higher groups, such as orders, classes, and phyla.

This striking personage in the history of biological science, who has made such an ineffaceable impression on the philosophy of biology, certainly demands more than a brief éloge to keep alive his memory.

Jean-Baptiste-Pierre-Antoine de Monet, Chevalier de Lamarck, was born August 1, 1744, at Bazentin-le-Petit. This little village is situated in Picardy, or what is now the Department of the Somme, in the Arrondissement de Péronne, Canton d'Albert, a little more than four miles from Albert, between this town and Bapaume, and near Longueval, the nearest post-office to Bazentin. The village of Bazentin-le-Grand, composed of a few more houses than its sister hamlet, is seen half a mile to the southeast, shaded by the little forest such as borders nearly every town and village in this region. The two hamlets are pleasantly situated in a richly cultivated country, on the chalk uplands or downs of Picardy, amid broad acres of wheat and barley variegated with poppies and the purple cornflower, and with roadsides shaded by tall poplars.

The peasants to the number of 251 compose the diminishing population. There were 356 in 1880, or about that date. The silence of the single little street, with its one-storied, thatched or tiled cottages, is at infrequent intervals broken by an elderly dame in her sabots, or by a creaking, rickety village cart driven by a farmer-boy in blouse and hob-nailed shoes. The largest inhabited building is the mairie, a modern structure, at one end of which is the village school, where fifteen or twenty urchins enjoy the instructions of the worthy teacher. A stone church, built in 1774, and somewhat larger than the needs of the hamlet at present require, raises its tower over the quiet scene.

Our pilgrimage to Bazentin had for its object the discovery of the birthplace of Lamarck, of which we could obtain no information in Paris. Our guide from Albert took us to the mairie, and it was with no little satisfaction that we learned from the excellent village teacher, M. Duval, that the house in which the great naturalist was born was still standing, and but a few steps away, in the rear of the church and of the mairie. With much kindness he left his duties in the schoolroom, and accompanied us to the ancient structure.

The modest château stands a few rods to the westward of the little village, and was evidently the seat of the leading family of the place. It faces east and is a two-storied house of the shape seen everywhere in France, with its high, incurved roof; the walls, nearly a foot and a half thick, built of brick; the corners and windows of blocks of white limestone. It is about fifty feet long and twenty-five feet wide. Above the roof formerly rose a small tower. There is no porch over the front door. Within, a rather narrow hall passes through the centre, and opens into a large room on each side. What was evidently the drawing-room or salon was a spacious apartment with a low white wainscot and a heavy cornice. Over the large, roomy fireplace is a painting on the wood panel, representing a rural scene, in which a shepherdess and her lover are engaged in other occupations than the care of the flock of sheep visible in the distance. Over the doorway is a smaller but quaint painting of the same description. The house is uninhabited, and perhaps uninhabitable--indeed almost a ruin--and is used as a storeroom for wood and rubbish by the peasants in the adjoining house to the left, on the south.

The ground in front was cultivated with vegetables, not laid down to a lawn, and the land stretched back for perhaps three hundred to four hundred feet between the old garden walls.

Here, amid these rural scenes, even now so beautiful and tranquil, the subject of our sketch was born and lived through his infancy and early boyhood.

If his parents did not possess an ample fortune, they were blessed with a numerous progeny, for Lamarck was the eleventh and youngest child, and seems to have survived all the others. Biographers have differed as to the date of the birth of Lamarck. Happily the exact date had been ascertained through the researches of M. Philippe Salmon; and M. Duval kindly showed us in the thin volume of records, with its tattered and torn leaves, the register of the Acte de Naissance, and made a copy of it, as follows:

Extrait du Registre aux Actes de Baptême de la Commune de Bazentin, pour l'Année 1744.

L'an mil sept cent quarante-quatre, le premier août est né en légitime mariage et le lendemain a été baptisé par moy curé soussigné Jean Baptiste Pierre Antoine, fils de Messire Jacques Philippe de Monet, chevalier de Lamarck, seigneur des Bazentin grand et petit et de haute et puissante Dame Marie Françoise de Fontaine demeurant en leur château de Bazentin le petit, son parrain a été Messire Jean Baptiste de Fossé, prêtre-chanoine de l'église collégiale de St. Farcy de Péronne, y demeurant, sa marraine Dame Antoinette Françoise de Bucy, nièce de Messire Louis Joseph Michelet, chevalier, ancien commissaire de l'artillerie de France demeurante au château de Guillemont, qui ont signé avec mon dit sieur de Bazentin et nous.

Ont signé: De Fossé, De Bucy Michelet, Bazentin. Cozette, curé.

Of Lamarck's parentage and ancestry there are fortunately some traces. In the Registre aux Actes de Baptême pour l'Année 1702, still preserved in the mairie of Bazentin-le-Petit, the record shows that his father was born in February, 1702, at Bazentin. The infant was baptised February 16, 1702, the permission to the curé by Henry, Bishop of Amiens, having been signed February 3, 1702. Lamarck's grandparents were, according to this certificate of baptism, Messire Philippe de Monet de Lamarck, Ecuyer, Seigneur des Bazentin, and Dame Magdeleine de Lyonne.
